Key Differentiators

- True 10-bit accuracy with no missing codes (vs ADC0804LCWM)
- Bipolar input range capability (vs ADC0804LCWM)
Design Notes
The AD571SD/883B requires dual supplies: +5 V and -12 V or -15 V. Ensure that the negative supply is stable and well-filtered, as it affects the analog input range and conversion accuracy. Use 0.1 µF ceramic capacitors close to the V+ and V- pins to decouple high-frequency noise.
For optimal performance, separate analog and digital ground planes and connect them at a single point near the ADC. Keep the analog input trace short and shielded to minimize noise pickup. Place the ADC close to the signal source to reduce parasitic capacitance and inductance.
Do not exceed the absolute maximum ratings for the analog input voltage, which are typically -0.5 V to V+ +0.5 V. Also, ensure that the digital output pins are not loaded beyond the specified drive capability. When using the external clock option, ensure it is stable and within the specified frequency range.
