AD623ARM General Description

The AD623 is an integrated, single- or dual-supply instrumentationamplifier that delivers rail-to-rail output swing using supplyvoltages from 3 V to 12 V. The AD623 offers superior userflexibility by allowing single gain set resistor programming and byconforming to the 8-lead industry standard pinout configuration.With no external resistor, the AD623 is configured for unitygain (G = 1), and with an external resistor, the AD623 can beprogrammed for gains of up to 1000.

The superior accuracy of the AD623 is the result of increasingac common-mode rejection ratio (CMRR) coincident withincreasing gain; line noise harmonics are rejected due toconstant CMRR up to 200 Hz. The AD623 has a wide inputcommon-mode range and amplifies signals with commonmodevoltages as low as 150 mV below ground. The AD623maintains superior performance with dual and single polaritypower supplies.

Key Features

The features of AD623ARM include easy to use
higher performance than discrete design
single-supply and dual-supply operation
rail-to-rail output swing
input voltage range extending 150 mV below ground (single supply)
low power consumption with a maximum supply current of 550 μA
gain set with one external resistor
and a gain range of 1

Application

The AD623ARM is commonly used in applications where common-mode rejection and precise amplification of differential signals are required
such as thermocouple amplifiers and instrumentation systems
