Description
The TS185x (single, dual and quad) can operate
with voltages as low as 1.8 V. They feature both
input and output rail-to-rail (1.71 at V
CC
= 1.8 V,
R
L
=2kΩ), 120 μA current consumption and
530 kHz gain bandwidth product.
With this low consumption and a sufficient GBP
for many applications, these operational
amplifiers are well-suited to all kinds of battery
supplied and portable applications.
The TS1851 is housed in the space-saving 5-pin
SOT23-5 package, which simplifies board design
(outside dimensions are 2.8 mm x 2.9 mm).
