AD8293G80/AD8293G160 is a low-cost, zero-drift in-amp with filter and fixed gain from Analog Devices. The device features a small 8-lead SOT-23 package, low offset voltage, low offset drift, high CMR, low noise and single-supply operation. AD8293G80/AD8293G160 is suitable for applications such as current sensing, strain gauges, laser diode control loops, portable medical instruments and thermocouple amplifiers.
The AD8293G80/AD8293G160 are small, low‑cost precision instrumentation amplifiers that integrate gain‑setting and filter resistors, reducing external component count. They operate from a single supply of 1.8 V to 5.5 V and provide rail‑to‑rail output, making them suitable for current sensing, strain‑gauge, laser‑diode control, portable medical instruments, and thermocouple amplification.
Key specifications include a typical voltage noise of 0.7 µV p‑p (0.01 Hz‑10 Hz), common‑mode rejection of 140 dB, power‑supply rejection of up to 120 dB, and a temperature range of –40 °C to +85 °C. The device is offered in an 8‑lead SOT‑23 package and is RoHS‑compliant.
