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 @ V_CC= 1.8V,
R_L= 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).
