AD8222:  仪表放大器LFCSP-16封装

The AD8222 is the first dual instrumentation amplifier in the small 4 mm × 4 mm LFCSP. It requires the same board area as a typical single instrumentation amplifier. The smaller package allows a 2× increase in channel density and a lower cost per channel, all with no compromise in performance.The AD8222 can also be configured as a single-channel, differential output instrumentation amplifier. Differential outputs provide high noise immunity, which can be useful when the output signal must travel through a noise environment, such as with remote sensors. The configuration can also be used to drive differential input ADCs.

The AD8222 maintains a minimum CMRR of 80 dB to 4 kHz for all grades at G = 1. High CMRR over frequency allows the AD8222 to reject wideband interference and line harmonics, greatly simplifying filter requirements. The AD8222 also has a typical CMRR drift over temperature of just 0.07 µV/V/°C at G = 1.The AD8222 operates on both single and dual supplies and only requires 2.2 mA maximum supply current for both amplifiers. It is specified over the industrial temperature range of -40°C to +85°C and is fully RoHS compliant.For a single-channel version, see the AD8221.
