The ISL28133A is a single micropower, chopper-stabilized operational amplifier designed for precision and efficiency in compact spaces. With a quiescent current of just 22µA and rail-to-rail input/output, it delivers exceptional performance across a wide supply range of 1.8V to 5.5V. Its ultra-low input offset voltage (10µV max) and minimal noise make it ideal for high-accuracy applications like medical instrumentation, temperature sensing, and electronic weight scales. The device operates across the temperature range of -40°C to +125°C and is available in both an SOT23-5 and SC70-5 packages.
