Description
The TS187x (single, dual and quad) device can
operate with voltages as low as 1.8 V. They
feature both input and output rail-to-rail.
The common mode input voltage extends 200 mV
beyond the supply voltages at 25 °C, while the
output voltage swing is within 100 mV of each rail
with a 600
Ω
load resistor. The devices consume
typically 400 µA per channel while offering
1.6 MHz of gain bandwidth product. The
amplifiers provide a high output drive capability at
typically 65 mA loads.
These features make the TS187x family ideal for
sensor interface, battery supplied and portable
applications.

1. All voltage values, except differential voltage, are with respect to network terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
If V
id
> ±1 V, the maximum input current must not exceed ±1 mA. When V
id
> ±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
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 k
Ω
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
CC
can cause excessive heating. The maximum output current is
approximately 80 mA, independent of the magnitude of V
CC
. Destructive dissipation can result from
simultaneous short-circuits on all amplifiers.
