FEATURES
DESCRIPTION
2
• GAIN BANDWIDTH PRODUCT: 5.5MHz
The OPA377 family of operational amplifiers are
wide-bandwidth CMOS amplifiers that provide very
• LOW NOISE: 7.5nV/√Hz at 1kHz
low noise, low input bias current, and low offset
• OFFSET VOLTAGE: 1mV (max)
voltage while operating on a low quiescent current of
• INPUT BIAS CURRENT: 0.2pA
0.76mA (typ).
• RAIL-TO-RAIL OUTPUT
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
• EMI INPUT FILTERING
ideal for a wide range of applications, including small
• QUIESCENT CURRENT: 0.76mA/ch
signal conditioning, audio, and active filters. In
• SUPPLY VOLTAGE: 2.2V to 5.5V
addition, these parts have a wide supply range with
• SMALL PACKAGES: excellent PSRR, making them attractive for
applications that run directly from batteries without
SC70, SOT23, and MSOP
regulation.
APPLICATIONS
The OPA377 is available in the SC70-5, SOT23-5,
• PHOTODIODE PREAMP
and SO-8 packages. The dual OPA2377 is offered in
the SO-8 and MSOP-8, and the quad OPA4377 in the
• PIEZOELECTRIC SENSOR PREAMP
TSSOP-14 packages. All versions are specified for
• SENSOR SIGNAL CONDITIONING
operation from –40°C to +125°C.
• AUDIO EQUIPMENT
• ACTIVE FILTERS
