Low input bias current op amps are required whenever the difference of currents or voltage is small and needs to be measured accurately. These op amps are used so that the signal is not loaded down by the input of the op amps. Low input bias current op amps are critical for interfacing sensors in applications from photodiodes, pH meters, or other electrometer related functions to downstream electronics. Analog Devices has many precision op amps that fit the definition and range of these applications.

PI-41701 - Pulse Instruments

The PI-41701 is a dual channel bipolar DC Bias supply that can provide an output current up to 100 mA per channel. The output voltage ranges from –8 V to +8 V and features programmable current limits with LED indicators and software interrupt to show/alert the user if the channel is in current limit. This card has special filter circuitry to reduce the output noise for those applications that require a low noise bias output.
