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
R
=2kΩ), 120 μA current consumption and
L
530 kHz gain bandwidth product.
With this low consumption and a sufficient GBP

1. All voltage values, except differential voltages, are with respect to network terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. If
> ±1 V, the maximum input current must not exceed ±1 mA. When Vid > ±1 V, add an input series
V
id
resistor to limit the input current.
3. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-
circuits on all amplifiers.
4. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
5. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins are floating.
6. Charged device model: all pins and package are charged together to the specified voltage and then
discharged directly to ground through only one pin. This is done for all pins.
7. Short-circuits from the output to V
approximately 48 mA, independent of the magnitude of V
