Key Differentiators
- Pin-for-pin compatible with 18-bit AD7982 (vs AD7982BRMZ)
- Low power consumption of 7 mW at 1 MSPS (vs AD7983BRMZ)
- Available in both MSOP and LFCSP packages (vs AD7980BCPZ-RL7)
Design Notes
The AD7980ARMZRL7 operates from a single 2.5V supply. Ensure that the supply is clean and well-decoupled with a 0.1uF ceramic capacitor placed close to the VDD pin. The reference voltage (REF) should also be decoupled with a 10uF capacitor to maintain stability and accuracy.
For optimal performance, place the AD7980ARMZRL7 close to the signal source to minimize trace length and reduce noise pickup. Use a solid ground plane and avoid routing digital signals near the analog input. The SPI lines should be kept short and shielded if necessary to prevent crosstalk.
The analog input must be driven by a low-impedance source to avoid sampling errors. Use an op-amp buffer if the source impedance is high. Also, ensure that the reference voltage is stable and within the specified range, as it directly affects conversion accuracy. Avoid exceeding the absolute maximum ratings on any pin.
