FEATURES

DESCRIPTION

• 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

In the case of input and output pins, this protection primarily consists of current steering diodes connected between the input and power-supply pins.

Figure 25 shows a 50kHz, 2nd-order, low-pass filter. The components have been selected to provide a maximally-flat Butterworth response. Beyond the cutoff frequency, roll-off is –40dB/dec.
