Overview

The OPA928 evaluation module (EVM) provides a platform to test the performance of the OPA928 femptoampere input-bias-current operational amplifier. OPA928EVM uses advanced guarding and shielding techniques to ensure femtoampere-level printed-circuit-board (PCB) layout performance. Both high-impedance (Hi-Z) buffer and transimpedance-amplifier (TIA) configurations are featured to evaluate the OPA928 in common application circuits.

Features
  • Low-leakage design for femtoampere input-bias performance
  • Advanced guarding and shielding techniques
  • High-impedance amplifier
  • Transimpedance amplifier (TIA)
  • Low-leakage T-switch
  • Guarded diode limiter
