AD8220ARMZ-R7

JFET输入仪表放大器具有轨到轨输出，采用MSOP封装 JFET Input Instrumentation Amplifier with Rail-to-Rail Output in MSOP Package

GENERAL DESCRIPTION

The AD8220 is the first single-supply JFET input instrumentation amplifier available in an MSOP package. Designed to meet the needs of high performance, portable instrumentation, the AD8220 has a minimum common-mode rejection ratio CMRR of 86 dB at dc and a minimum CMRR of 80 dB at 5 kHz for G = 1. Maximum input bias current is 10 pA and typically remains below 300 pA over the entire industrial temperature range. Despite the JFET inputs, the AD8220 typically has a noise corner of only 10 Hz.
