General Description

The COMLINEAR CLC2057 is a low noise, dual voltage feedback amplifier

that is internally frequency compensated to provide unity gain stability. The

CLC2057 offers over 13MHz of unity gain bandwidth and excellent (110dB)

CMRR, PSRR, and open loop gain. The CLC2057 also features low input volt-

age noise (4nV/√Hz) and low distortion (0.0005%) making it well suited for

audio applications such as audio filtering. Other applications include indus-

trial measurement tools, pre-amplifiers, and other circuits that require well-

matched channels.

The COMLINEAR CLC2057 is designed to operate over a wide power supply

voltage range, ±2V to ±18V (4V to 36V). It utilizes an industry standard

dual amplifier pin-out and is available in a Pb-free, RoHS compliant SOIC-8

package.
