Key Differentiators
- Higher sampling rate than AD7983 (vs AD7983BRMZ)
- Lower power than AD7982 (vs AD7982BRMZ)
- Pin-compatible with 18-bit AD7982 (vs AD7982BRMZ)
Design Notes
The AD7980ARMZRL7 operates from a 2.5 V supply and consumes 7 mW at 1 MSPS. Power scales linearly with throughput, so reduce the sampling rate to save power in battery-powered designs. Use a low-noise LDO to supply VDD and decouple with 0.1 Β΅F and 10 Β΅F capacitors close to the pin.
Place the ADC close to the signal source to minimize trace length and noise pickup. Use a solid ground plane and separate analog and digital grounds, connecting them at a single point. Keep the SPI bus traces short and avoid routing them near high-speed digital signals.
Ensure the reference voltage is stable and well-decoupled, as it directly affects conversion accuracy. The analog input should be driven by a low-impedance source to avoid sampling errors. Do not exceed the absolute maximum ratings for VDD and input pins, and ensure proper power-up sequencing.
