Overview
The TS1874AIYDT is a quad operational amplifier from STMicroelectronics, part of the TS187x family. This device is designed to operate with supply voltages as low as 1.8 V and features both input and output rail-to-rail capabilities. It is particularly suited for low-power, battery-supplied, and portable applications due to its low supply current and high output drive capability.
