The AD623 is an integrated single supply instrumentation amplifier that delivers rail-to-rail output swing on a single supply +3 V to +12 V supplies; The AD623 offers superior user flexibility by allowing single gain set resistor programming, and 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 up to 1.000; The 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 200Hz; The AD623 has a wide input common-mode range and can amplify signals that have a common-mode voltage 150mV below ground; The AD623 still provides superior performance when operated from a dual voltage supply °À2.5 V to °À6.0 V; Low power consumption 1.5mW at 3 V, wide supply voltage range, and rail-to-rail output swing make the AD623 ideal for battery powered applications;
The rail-to-rail output stage maximizes the dynamic range when operating from low supply voltages; The AD623 replaces discrete instrumentation amplifier designs and offers superior linearity, temperature stability and reliability in a minimum of space; Applications:low power medical instrumentation, transducer interface, thermocouple amplifier, industrial process controls, difference amplifier, low power data acquisition.
