GENERAL DESCRIPTION  
to alleviate this problem, the AD8224 can operate on a 18 ꢀ  
dual supply, as well as on a single +5 ꢀ supply. The device’s 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 ꢀ supply eliminates the need for higher  
voltage, dual supplies. The AD8224 draws 750 μA of quiescent  
current per amplifier, making it ideal for battery powered  
devices.  
The AD8224 is the first single-supply, JFET input instrumentation  
amplifier available in the space-saving 16-lead, 4 mm × 4 mm  
LFCSP. It requires the same board area as a typical single  
instrumentation amplifier yet doubles the channel density  
and offers a lower cost per channel without compromising  
performance.  
Designed to meet the needs of high performance, portable  
instrumentation, the AD8224 has a minimum common-mode  
rejection ratio (CMRR) of 86 dB at dc and a minimum CMRR  
of 80 dB at 10 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  
AD8224 typically has a noise corner of only 10 Hz.  
In addition, the AD8224 can 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 noisy environment, such  
as with remote sensors. The configuration can also be used to  
drive differential input ADCs. For a single-channel version, use  
the AD8220.  
With the proliferation of mixed-signal processing, the number  
of power supplies required in each system has grown. Designed
