The INA122 is a precision instrumentation amplifier designed for low-noise differential signal acquisition, suitable for applications in portable electronics, field transmitters, and medical devices such as electrocardiograms. It operates on a single supply voltage ranging from 2.2V to 36V and features a low quiescent current of 60OºA, making it ideal for battery-powered applications. The amplifier provides a rail-to-rail output swing and has a maximum offset voltage of 250OºV with a drift of 3OºV/¬8C, ensuring high accuracy. Gain can be set from 5V/V to 10000V/V using a single external resistor. The INA122 is available in both 8-pin PDIP and SOIC packages, with a specified operating temperature range of -40¬8C to +85¬8C.
