AD8293G80BRJZ-R7

AD8293G80BRJZ-R7 is a low-cost, zero-drift in-amp with filter and fixed gain. It is a small, precision instrumentation amplifier that has low noise and rail-to-rail outputs. It incorporates the gain setting resistors and filter resistors, reducing the number of ancillary components. For example, only two external capacitors are needed to implement a 2-pole filter. It also features low offset voltage, offset drift, and gain drift coupled with high common mode rejection. It is capable of operating on a supply of 1.8V to 5.5V. Precision instrumentation, position and pressure sensors, medical instrumentation, and strain gauge amplifiers benefit from the low noise, low input bias current, and high common mode rejection. The small footprint and low cost are ideal for high-volume applications. It is used in applications such as current sensing, strain gauges, laser diode control loops, portable medical instruments, and thermocouple amplifiers.
