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.
