The low offset and drift ensure accurate control loop performance. The amplifier's robustness over -40°C to +85°C makes it suitable for harsh environments. Its low power consumption reduces heat generation in control cabinets. The 8-SOIC package is easy to integrate into existing designs.

🎧

Audio Signal Processing

Although the OP90GSZ-REEL7 has a limited bandwidth of 20 kHz, it can be used in low-power audio applications such as hearing aids and portable audio players. Its low supply current is critical for battery life in wearable audio devices. The amplifier's low noise and distortion contribute to clean audio reproduction. The rail-to-rail output maximizes dynamic range in single-supply designs. Its small package allows compact audio circuit designs.

What is the supply voltage range of OP90GSZ-REEL7?
The OP90GSZ-REEL7 operates from a single supply of 1.6V to 36V or dual supplies of ±0.8V to ±18V. According to the Analog Devices OP90 datasheet, this wide range allows use in both battery-powered and industrial applications. The low minimum voltage of 1.6V makes it suitable for 2-cell alkaline or single-cell lithium-ion systems.
What is the supply current of OP90GSZ-REEL7?
The OP90GSZ-REEL7 has a maximum supply current of 20 µA. This micropower consumption is a key feature for battery-powered devices, as it extends battery life significantly. For example, a 200 mAh battery could power the amplifier for over 10,000 hours (over a year) in continuous operation, assuming no other loads.
What is the gain bandwidth product of OP90GSZ-REEL7?
The OP90GSZ-REEL7 has a gain bandwidth product of 20 kHz. This low bandwidth is typical for micropower precision amplifiers, prioritizing low power consumption over speed. It is suitable for DC and low-frequency AC signals, such as sensor outputs and audio frequencies up to 20 kHz, but not for high-speed video or RF applications.
What is the slew rate of OP90GSZ-REEL7?
The OP90GSZ-REEL7 has a slew rate of 0.012 V/µs. This slow slew rate limits the amplifier's ability to track fast-changing signals, making it unsuitable for high-frequency applications. It is designed for precision DC and low-frequency signals where accuracy is more important than speed.
Can OP90GSZ-REEL7 operate from a single supply?
Yes, the OP90GSZ-REEL7 is designed for true single-supply operation. Its input voltage range includes ground, allowing it to process signals down to 0V. This makes it ideal for battery-powered systems where a negative supply is not available. The output can also swing close to ground, maximizing dynamic range.
What is the input offset voltage of OP90GSZ-REEL7?
The OP90GSZ-REEL7 has a typical input offset voltage of 150 µV. This low offset is important for precision applications, as it directly affects DC accuracy. For example, in a sensor interface with a gain of 100, a 150 µV offset would result in a 15 mV output error, which may be acceptable in many applications.
What is the input bias current of OP90GSZ-REEL7?
The OP90GSZ-REEL7 has an input bias current of 4 nA. This low bias current minimizes errors when driving high-impedance sources, such as pH sensors or photodiodes. It also reduces the need for input bias current compensation resistors, simplifying circuit design.
What is the output drive capability of OP90GSZ-REEL7?
The OP90GSZ-REEL7 can source or sink a minimum of 5 mA of output current. This allows it to drive moderate loads, such as LEDs, small relays, or the input of an ADC. For higher current loads, an external buffer or transistor stage may be required.
Is OP90GSZ-REEL7 suitable for battery-powered applications?
Yes, the OP90GSZ-REEL7 is specifically designed for battery-powered applications. Its low supply current of 20 µA max and operation down to 1.6V make it ideal for portable devices, remote sensors, and wearable electronics. The low power consumption ensures minimal drain on the battery, extending operational life.
What is the difference between OP90GSZ-REEL7 and OP90GSZ-REEL?
The OP90GSZ-REEL7 and OP90GSZ-REEL are functionally identical, differing only in packaging and reel size. The REEL7 suffix indicates a 7-inch reel, while REEL indicates a 13-inch reel. Both are 8-pin SOIC, tape and reel, and have the same electrical specifications. The choice depends on assembly line requirements.
What is the best drop-in replacement for OP90GSZ-REEL7?
The best drop-in replacement for OP90GSZ-REEL7 is the OP90GSZ-REEL (same die, same package, same pinout, 100% compatible). Other pin-compatible alternatives include the OP90GS-REEL (same package, but may have different temperature grade) and the OP90GP (DIP package, not drop-in). For cross-brand, the LM358 is not pin-compatible, so verify before use.

Selection Guide

Choose the OP90GSZ-REEL7 when you need a micropower precision op amp for battery-powered or low-power applications. Its 20 µA supply current and 1.6V minimum supply voltage make it ideal for portable devices. If you do not need the 7-inch reel, the OP90GSZ-REEL (13-inch reel) is a drop-in alternative. For through-hole designs, the OP90GP is available but requires a different footprint. The LM358 is a lower-cost alternative but has higher power consumption and lower precision, so it is only suitable for non-critical applications. For automotive or high-temperature environments, verify the temperature grade of the specific variant.

Key Differentiators

  • Ultra-low supply current of 20 µA max (vs LM358)
  • Wide supply voltage range down to 1.6V (vs LM358)
  • Precision input offset voltage of 150 µV (vs LM358)

Design Notes

The OP90GSZ-REEL7 operates from 1.6V to 36V single supply. For battery-powered designs, ensure the supply voltage does not drop below 1.6V during discharge. Use a low-dropout regulator if needed to maintain voltage. Decouple the supply pins with 0.1µF ceramic capacitors close to the device to prevent instability.

For optimal performance, place the OP90GSZ-REEL7 on a PCB with a solid ground plane. Keep input traces short and shielded to minimize noise pickup. Use surface-mount components to reduce parasitic inductance. The SOIC package has a thermal pad; connect it to the ground plane for better heat dissipation, though power dissipation is low.

Do not exceed the absolute maximum supply voltage of 36V. The input common-mode range includes ground, but do not apply voltages beyond the supply rails. The output can swing close to the rails but not exactly to them; account for this in your design. Avoid using this amplifier for high-frequency signals due to its low bandwidth.
