OPA2378

SBOS417–JANUARY 2008

Low Noise, 900kHz, 50µV, Rail-to-Rail Input/Output

Precision OPERATIONAL AMPLIFIER

Zerø-Drift Series

FEATURES

DESCRIPTION

•

LOW NOISE 0.1Hz to 10Hz: 0.4µV_PP

LOW OFFSET VOLTAGE: 15µV (typ)

QUIESCENT CURRENT: 100µA (typ)

OFFSET DRIFT: 0.1µV/°C (typ)

•

The OPA378 and OPA2378 represent

a new

generation of micropower operational amplifiers.

Rail-to-rail input, low input offset voltage (50µV max),

low quiescent current (125µA max), and 900kHz

bandwidth make this part very attractive for

low-power precision applications. In addition, this part

has excellent PSRR, making it an outstanding choice

for applications that run directly from batteries without

regulation.

SINGLE-SUPPLY OPERATION

SUPPLY VOLTAGE: 1.8V to 5.5V

microSIZE PACKAGES: SC70 and SOT23

APPLICATIONS

The OPA378 (single version) is available in a

microSIZE SC70-5 and SOT23-5. The OPA2378

(dual version) is offered in s SOT23-8 package. All

versions are specified for operation from –40°C to

+125°C.
