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