Key Features
- Ultralow maximum input bias current of 270 pA at 25°C enables precision measurement with high-impedance sources such as ion-selective electrodes, strain gauges, and thermocouple bridges
- Exceptional common-mode rejection ratio with 98 dB minimum and 128 dB nominal CMRR provides outstanding differential signal accuracy in the presence of common-mode noise and ground potential differences
- Quad matched bipolar op-amp channel configuration in a 16-pin SOIC package ensures tight channel-to-channel offset and gain matching for multi-channel precision instrumentation designs
- Voltage-feedback architecture supports a wide range of closed-loop gain configurations and standard compensation networks, simplifying design for precision DC and low-frequency AC amplifier stages
Applications
The AD704AR-16-REEL is used in precision data acquisition systems, medical instrumentation, and scientific measurement equipment where four matched low-bias-current amplifiers are needed for accurate multi-channel sensor signal conditioning. It is particularly well-suited for electrochemical sensor interfaces, bridge amplifiers, and thermocouple signal chains that require the extremely low 270 pA bias current and 128 dB nominal CMRR to preserve measurement accuracy. Its 16-pin SOIC tape-and-reel format supports high-volume automated PCB assembly for professional analytical instruments.
