技术问答

WILLSEMI WS722377 is a wide bandwidth CMOS amplifier that provides very low noise, low input bias current, and low offset voltage while operating on a low quiescent current of 1.3mA per channel.

CMOS Operational Amplifier WS722377 is optimized for low-voltage, single-supply applications. The exceptional combination of AC and DC performance makes 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.

The WS722377 is available with MSL 3 Level in SOP-8L, MSOP-8L, and DFN3x3-8L packages.

Standard products are Pb-Free and halogen-Free.

Features
• Gain Bandwidth Product: 13.7MHz
• Low Noise @1kHz : 7nV/√Hz
• Offset Voltage: 25μV
• Input Bias Current: 5pA
• Quiescent Current per OPA: 1.3mA
• Supply Voltage Range: 2.1~5.5V
• Rail-to-Rail Output Swing
• Unity Gain Stable
• EMI Input Filtering
• -40℃ to 125℃ Operation Range

Applications
• Photo Diode Pre-Amp
• Piezoelectric Sensor Pre-Amp
• Sensor Signal Conditioning
• Audio Equipment
• Active Filter

Pin Descriptions

Absolute Maximum Ratings

Note:
1. Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions
for extended periods may degrade device reliability. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those specified is not supported.
2. Input terminals are diode-clamped to the power supply rails. Input signals that can swing more than 0.5V
beyond the supply rails should be currently limited to 10mA or less.
3. Short-circuit to ground, one amplifier per package. Differential voltages are at +IN with respect to -IN.

Electronics Characteristics: VS = +2.2V to +5.5V
TA=25℃, RL=10kΩ, connected to VS/2, VCM=VOUT=VS/2, unless otherwise noted..
