7.1 Application Information

The OPA928 offers femtoampere level input bias current, and excellent dc precision and ac performance. This device provides 2.5MHz bandwidth and very low noise, 15nV/√Hz and 0.07fA/√Hz. The OPA928 can operate with a 36V supply and provides a wider linear output voltage swing than comparable op amps. The ultra-low input bias, low noise and wide output voltage swing capability make this device an excellent choice for high impedance buffer and transimpedance amplifier applications.
