LM837 Low Noise Quad Operational Amplifier

Check for Samples: LM837

FEATURES

DESCRIPTION

The LM837 is a quad operational amplifier designed

• High Slew Rate 10 V/μs (typ); 8 V/μs (min)

for low noise, high speed and wide bandwidth

• Wide Gain Bandwidth Product 25 MHz (typ); 15

performance. It has a new type of output stage which

MHz (min)

can drive a 600Ω load, making it ideal for almost all

• Power Bandwidth 200 kHz (typ)

digital audio, graphic equalizer, preamplifiers, and

professional audio applications. Its high performance

• High Output Current ±40 mA

characteristics also make it suitable for

• Excellent Output Drive Performance >600Ω

instrumentation applications where low noise is the

• Low Input Noise Voltage 4.5 nV/√Hz

key consideration.

• Low Total Harmonic Distortion 0.0015%

The LM837 is internally compensated for unity gain

• Low Offset Voltage 0.3 mV

operation. It is pin compatible with most other

standard quad op amps and can therefore be used to

upgrade existing systems with little or no change.
