Key Differentiators
- Ultra-low offset voltage of ±4 µV (vs ADA4522-1ARZ)
- Lower input noise (88 nV p-p vs 100 nV p-p) (vs OPA189IDR)
- Compact LFCSP package (vs ADA4523-1BRMZ)
Design Notes
The ADA4523-1BCPZ operates from 4.5 V to 36 V. Ensure the supply voltage is within this range and properly decoupled with 0.1 µF ceramic capacitors placed close to the V+ and V- pins. For high-frequency noise, add a 10 µF tantalum capacitor in parallel. The wide supply range allows use in both low-voltage and high-voltage systems, but verify that the input common-mode voltage does not exceed the supply rails.
For optimal performance, place the ADA4523-1BCPZ on a PCB with a solid ground plane. Keep the input traces short and shielded to minimize noise pickup. The exposed pad on the LFCSP package should be soldered to the PCB ground to improve thermal performance. Use a 4-layer stackup with dedicated power and ground planes to reduce EMI.
Avoid exceeding the absolute maximum supply voltage of 36 V, as this can damage the device. Also, ensure that the input voltage does not exceed the supply rails, as this can cause latch-up. The zero-drift architecture requires a settling time after power-up; allow at least 100 µs for the self-calibration to complete before taking measurements. Additionally, the output can swing rail-to-rail, but driving capacitive loads directly may cause instability; use a series resistor if necessary.
