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
