The JFET input stage architecture offers the advantages of low input bias current, high bandwidth, high gain, low noise, and no phase reversal when the applied input signal exceeds the common voltage range. The output stage is rail to rail with high drive characteristics and low dropout voltage for both sinking and sourcing currents. ADA4610-2 amplifiers are unconditionally stable for all gain configurations, even with capacitive loads well in excess of 1nF.
The devices are designed with internal protective circuitry that allows voltages as high as 0.3V beyond the supplies to be applied at the input of either terminal without causing damage. The ADA4610-2 B grades achieve less than 0.4mV of offset and 4μV/°C of offset drift, which are characteristics that are usually associated with very high precision bipolar input amplifiers.
The low power consumption characteristic of the ADA4610-2 family minimizes the die temperature, which warrants low input bias currents even at elevated ambient temperatures, making the amplifiers ideal for applications that require low leakage specifications without active cooling.
Fully specified with supply voltages from ±5V to ±15V over the extended industrial temperature range of −40°C to +125°C, ADA4610-2 Amplifiers are ideal for instrumentation, medical instruments, multipole filters, precision current measurement, photodiode amplifiers, audio, and sensors.
