Description
The TS187x (single, dual and quad) 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 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
