EL8171, EL8172 Micropower, Single Supply, Rail-to-Rail Input-Output Instrumentation Amplifiers
The EL8171 and EL8172 are micropower instrumentation amplifiers optimized for single‑supply operation from +2.4 V to +5.5 V. They feature rail‑to‑rail inputs and outputs, PMOS input devices with sub‑nA bias currents, and a feedback divider that sets gain.
The devices are supplied in an 8‑lead SOIC package, are RoHS‑compliant, and include specifications for supply current, offset voltage, bias current, bandwidth, and various performance curves across temperature and gain settings.
