The ISL28130FHZ-T7A is a single, low drift, RRIO operational amplifier in 5 pin SOT-23 package. This amplifier is optimized for single and dual supply operation from 1.8V to 5.5V and ±0.9V to ±2.75V. It's low supply current of 20µA and rail to rail input/output enable the IC to be an excellent general purpose op-amp for a range of applications. It is ideal for handheld devices that operate off 2AA or single Li-ion batteries. It is used in bi-directional current sense, temperature measurement, electronic weigh scales, precision/strain gauge sensor, precision regulation, low ohmic current sense and high gain analogue front ends.
