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.
