Analog Devices AD8278/AD8279 Datasheet
The AD8278 and AD8279 are low‑power, wide‑supply‑range difference amplifiers designed for precision signal‑conditioning in power‑critical applications. They offer high common‑mode rejection, low offset drift, and rugged over‑voltage protection, making them suitable for voltage and current monitoring, instrumentation amplifiers, and portable battery‑powered equipment.
The datasheet details electrical specifications such as supply current (200 pA for AD8278, 300 pA typical for AD8279), bandwidth (1 MHz at G=4, 550 kHz at G=2), slew rate (up to 1.4 V/ps), input voltage range, and temperature range (‑40 °C to +85 °C). Pin configurations for MSOP, SOIC and 14‑lead SOIC packages are included, along with absolute maximum ratings, thermal resistance, and ESD precautions.
