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.
With the proliferation of mixed-signal processing,the number of power supplies required in each system has grown.The AD8220 is designed to alleviate this problem.The AD8220 can operate on a ±18 V dual supply,as well as on a single +5 V supply.Its rail-to-rail output stage maximizes dynamic range on the low voltage supplies common in portable applications.Its ability to run on a single 5 V supply eliminates the need to use higher voltage,dual supplies.The AD8220 draws a maximum of 750 μA of quiescent current,making it ideal for battery-powered devices.
Gain is set from 1 to 1000 with a single resistor.Increasing the gain increases the common-mode rejection.Measurements that need higher CMRR when reading small signals benefit when the AD8220 is set for large gains.
A reference pin allows the user to offset the output voltage.This feature is useful when interfacing with analog-to-digital converters.
The AD8220 is available in an MSOP that takes roughly half the board area of an SOIC.Performance is specified over the industrial temperature range of 40°C to +85°C.（请准确翻译）
