Description

The TS185x (single, dual and quad) are

operational amplifiers able to operate with

voltages as low as 1.8V. They feature both input

and output rail-to-rail (1.71 @ VCC= 1.8V,

RL=2kΩ), 120μA current consumption and

480kHz gain bandwidth product.

With such a low consumption and a sufficient

GBP for many applications, this op-amp is very

well-suited for all kinds of battery-supplied and

portable equipment applications.

The TS1851 is housed in the space-saving 5-pin

SOT23-5 package which simplifies the board

design (outside dimensions are 2.8mm x 2.9mm).
