SBOS504B –FEBRUARY 2010–REVISED JANUARY 2011

5MHz, Low-Noise,

Single, Dual, Quad CMOS Operational Amplifiers

Check for Samples: OPA377, OPA2377, OPA4377

FEATURES

DESCRIPTION

•

GAIN BANDWIDTH PRODUCT: 5.5MHz

LOW NOISE: 7.5nV/√Hz at 1kHz

OFFSET VOLTAGE: 1mV (max)

INPUT BIAS CURRENT: 0.2pA

RAIL-TO-RAIL OUTPUT

The OPA377 family of operational amplifiers are

wide-bandwidth CMOS amplifiers that provide very

low noise, low input bias current, and low offset

voltage while operating on a low quiescent current of

0.76mA (typ).

The OPA377 op amps are optimized for low-voltage,

UNITY-GAIN STABLE

single-supply

applications.

The

exceptional

combination of ac and dc performance make them

ideal for a wide range of applications, including small

signal conditioning, audio, and active filters. In

addition, these parts have a wide supply range with

excellent PSRR, making them attractive for

applications that run directly from batteries without

regulation.

EMI INPUT FILTERING

QUIESCENT CURRENT: 0.76mA/ch

SUPPLY VOLTAGE: 2.2V to 5.5V

SMALL PACKAGES:

SC70, SOT23, and MSOP

APPLICATIONS

The OPA377 is available in the SC70-5, SOT23-5,

and SO-8 packages. The dual OPA2377 is offered in

the SO-8 and MSOP-8, and the quad OPA4377 in the

TSSOP-14 packages. All versions are specified for

operation from –40°C to +125°C.
