ADA4528-1ARMZ-R7

ADA4528-1 is an ultralow noise, zero-drift operational amplifier featuring rail-to-rail input and output swing. It has a wide operating supply range of 2.2V to 5.5V, high gain, and excellent CMRR, PSRR specifications, which make it ideal for applications that require precision amplification of low level signals, such as position and pressure sensors, strain gauges, and medical instrumentation. This amplifier is widely used in application such as thermocouple/thermopile, load cell and bridge transducers, precision instrumentation, electronic scales, handheld test equipment etc.
