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. Maxi-
mum 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 for the A and B grade is
specified over the industrial temperature range of 40°C to +85°C,
and the W grade is specified over the automotive temperature
range of 40°C to +125°C.
