The AD8273 is a low distortion, dual-channel amplifier with internal gain setting resistors. With no external components, it can be configured as a high performance difference amplifier (G = ½ or 2), inverting amplifier (G = ½ or 2), or unity gain amplifier (G = 1).
The AD8273 dual‑channel amplifier offers two gain settings (gain of 2) with a maximum gain error of 0.05 % and a gain drift of 10 ppm/°C. It operates from a 2.5 V to 18 V supply, drawing only 2.5 mA per channel, and provides a 20 MHz bandwidth, 20 V/µs slew rate, and 77 dB minimum CMRR.
Designed for high‑performance audio and instrumentation applications, the device works over an industrial temperature range of –40 °C to +85 °C, includes short‑circuit protection limiting output current to about 100 mA, and complies with RoHS requirements.
