AD623
GENERAL DESCRIPTION
The
AD623
is an integrated, single- or dual-supply instrumentation
amplifier that delivers rail-to-rail output swing using supply
voltages from 3 V to 12 V. The
AD623
offers superior user
flexibility by allowing single gain set resistor programming and by
conforming to the 8-lead industry standard pinout configuration.
With no external resistor, the
AD623
is configured for unity
gain (G = 1), and with an external resistor, the
AD623
can be
programmed for gains of up to 1000.
The superior accuracy of the
AD623
is the result of increasing
ac common-mode rejection ratio (CMRR) coincident with
increasing gain; line noise harmonics are rejected due to
constant CMRR up to 200 Hz. The
AD623
has a wide input
common-mode range and amplifies signals with common-
mode voltages as low as 150 mV below ground. The
AD623
maintains superior performance with dual and single polarity
power supplies.
