General Description
The COS9001 (single), COS9002 (dual) and
COS9004 (quad) are micro-power, rail-to-rail
input and output amplifiers operated on 1.8V to
7.0V supplies. Despite their low quiescent
current, the COS900x family provides excellent
overall performance and versatility. They have
both rail-to-rail input and output range. The
output voltage swing extends to within 10mV of
each rail, providing the maximum output
dynamic range with excellent overdrive
recovery.
COS900x family is unity gain stable and has a
gain bandwidth product of 1.5MHz (typical).
They provide high CMRR and PRSS
performance and can operate from a single
supply voltage as low as 1.8V.
The COS900xS devices include a shutdown
mode (COS9001S, and COS9002S) that allow
the amplifiers to switch off into standby mode
with typical current consumption less than 5 µA.
These features make the COS900x family well
suited for single-supply, battery-powered
applications. They can be used as plus-in
replacements for many commercially available
op-amps to reduce power and improve
input/output range and performance.

1. Pin Configuration and Functions
Pin Functions
Name
Description
Note
+Vs
Positive power supply
A bypass capacitor of 0.1μF as close to the part as
possible should be placed between power supply pins
or between supply pins and ground.
-Vs
Negative power supply
or ground
If it is not connected to ground, bypass it with a
capacitor of 0.1μF as close to the part as possible.
-IN
Negative input
Inverting input of the amplifier. Voltage range of this
pin can go from -Vs -0.3V to +Vs + 0.3V.
+IN
Positive input
Non-inverting input of the amplifier. This pin has the
same voltage range as –IN.
OUT
Output
The output voltage range extends to within millivolts
of each supply rail.
Shutdown
High: enable op-amp; Low: disable op-amp
