The AD8250 is an instrumentation amplifier with digitally programmable gains that has GΩ input impedance, low output noise, and high CMRR. It is suitable for applications such as data acquisition, biomedical analysis, and test and measurement.
The AD8250 is a programmable‑gain instrumentation amplifier offered by Analog Devices. It provides gains of 1, 2, 5, and 10, a wide supply range of +5 V to +15 V, and a small 10‑lead MSOP package, making it suitable for data‑acquisition and biomedical applications.
The device features a 10 MHz bandwidth, low distortion (‑110 dB THD), fast settling (615 ns to 0.001 %), and low noise (18 nV/√Hz at G=10). Detailed specifications, pin configurations, timing diagrams, and absolute maximum ratings are provided for designers.
