Key Differentiators
- Higher sampling rate than AD7690 (vs AD7690BRMZ)
- Pin-compatible with 18-bit AD7982 (vs AD7982BCPZ-RL7)
- Lower power than many competitors (vs MAX11166)
Design Notes
The AD7980ACPZ-RL7 operates from a single 2.5V supply. Use a low-noise LDO to generate VDD and place a 10uF ceramic capacitor close to the VDD pin. The reference voltage (REF) should be decoupled with a 10uF capacitor to ground to ensure stable operation.
For optimal performance, keep analog input traces short and shielded from digital signals. Use a solid ground plane and separate analog and digital ground areas if necessary. Place the ADC close to the signal source to minimize noise pickup.
Ensure the CNV pin is triggered with a clean, fast-rising edge to avoid false conversions. The BUSY signal should be monitored to prevent reading data before conversion is complete. Also, verify that the reference voltage is within the specified range and stable, as it directly affects accuracy.
Compliance Information
RoHS compliant per Analog Devices product page. AEC-Q100 not applicable for this commercial-grade ADC.
