DESCRIPTION
The TS185x (Single, Dual & Quad) is operational
amplifier able to operate with voltages as low as
1.8V and features both Input and Output Rail to
Rail (1.71 @ V
CC
= 1.8V, R
L
= 2k
), 120
A con-
sumption current and 480kHz Gain Bandwidth
Product.
With a such low consumption and a sufficient GBP
for many applications, this Op-Amp is very
well-suited for any kind of battery-supplied and
portable equipment applications.
The TS1851 is housed in the space-saving 5 pin
SOT23-5 package which simplifies the board de-
sign (outside dimensions are 2.8mm x 2.9mm).

1. All voltages values, except differential voltage are with respect to network terminal.
2. Differential voltages are non-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of input and output voltages must never exceed V
CC
+0.3V.
4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all amplifiers
