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 VCC = 1.8 V,
RL = 2 kΩ), 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).

See note
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
Vid > ±1 V, the maximum input current must not exceed ±1 mA. When Vid > ±1 V, add an input series
resistor to limit the input current.
3. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuits 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 VCC can cause excessive heating. The maximum output current is
approximately 48 mA, independent of the magnitude of VCC. Destructive dissipation can result from
simultaneous short-circuits on all amplifiers.
