Overview
The TS1851ILT is a single operational amplifier from STMicroelectronics, part of the TS185x family. This device is designed to operate with supply voltages as low as 1.8V and features both input and output rail-to-rail capabilities. It is particularly suited for battery-supplied and portable equipment due to its low power consumption and sufficient gain bandwidth product (GBP) for many applications. The TS1851ILT is housed in a space-saving 5-pin SOT23-5 package, which simplifies board design with outside dimensions of 2.8mm x 2.9mm.
