Description
1.8V, Input/ouput Rail to Rail Low Power Op-amps
Manufacturer

DESCRIPTION
The TS187x (Single, Dual & Quad) is an opera-
tional amplifier family able to operate with voltage
as low as 1.8V and features both I/O Rail to Rail.
The common mode input voltage extends 200mV
at 25°C beyond the supply voltages while the out-
put voltage swing is within 100mV of each Rail
with 600 Ohm 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 performances make the TS187X family ide-
al for sensor interface, battery-supplied and porta-
ble applications.
