This document describes the features and characteristics of the AD8253 iCMOS programmable gain instrumentation amplifier, including small package, programmable gain setting, wide supply range, excellent DC and AC performance.
The AD8253 is a programmable‑gain instrumentation amplifier offered in a 10‑lead MSOP package. It provides selectable gains of 1, 10, 100, and 1000, a wide supply range of +5 V to +15 V, and low noise and distortion performance suitable for data‑acquisition and biomedical applications.
The document includes a functional block diagram, detailed electrical specifications (CMRR, bandwidth, slew rate, settling time, power consumption), pin descriptions, timing diagrams, absolute maximum ratings, and ordering information. Typical performance graphs and statistical distributions illustrate the device’s CMRR, offset voltage, and noise characteristics.
