PRODUCT DE SCRIPT ION
T he AD623 is an integrated single supply instrumentation am-
plifier that delivers rail-to-rail output swing on a single supply
(+3 V to +12 V supplies). T he AD623 offers superior user flex-
ibility by allowing single gain set resistor programming, and
conforming to the 8-lead industry standard pinout configura-
tion. 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 up to 1,000.
T he AD623 holds errors to a minimum by providing superior
AC CMRR that increases with increasing gain. Line noise, as
well as line harmonics, will be rejected since the CMRR remains
constant up to 200 Hz. T he AD623 has a wide input common-
mode range and can amplify signals that have a common-mode
voltage 150 mV below ground. Although the design of the AD623
has been optimized to operate from a single supply, the AD623
still provides superior performance when operated from a dual
voltage supply (
±
2.5 V to
±
6.0 V).
Low power consumption (1.5 mW at 3 V), wide supply voltage
range, and rail-to-rail output swing make the AD623 ideal for
battery powered applications. T he rail-to-rail output stage maxi-
mizes the dynamic range when operating from low supply volt-
ages. T he AD623 replaces discrete instrumentation amplifier
designs and offers superior linearity, temperature stability and
reliability in a minimum of space. Until the AD623, this level of
instrumentation amplifier performance has not been achieved.
