Description

A difference amplifier with a single source, the AD8210YRZ is perfect for boosting small differential voltages when there are high common-mode voltages present. Between -2 V and +65 V is the operating input common-mode voltage range. 5 V is the usual supply voltage.

Offerings for the AD8210YRZ include a SOIC package. -40°C to +125°C is the operational temperature range.

Outstanding ac and dc performance across temperatures minimizes measurement loop error. Gain drift and offset drift are guaranteed to be no more than 20 ppm/°C and 8 μV/°C, respectively.

Using the VREF1 and VREF2 pins, the output offset can be changed from 0.05 V to 4.9 V with a 5 V supply. The output is set to half-scale by connecting the VREF1 pin to the V+ pin and the VREF2 pin to the GND pin. The output becomes unipolar and begins to rise above ground when both VREF1 and VREF2 are connected to GND. The output becomes unipolar when VREF1 and VREF2 are connected to V+ and begin close to V+. By giving VREF1 and VREF2 an external voltage, further offsets can be produced.
