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.

Evaluation Board Schematics
Evaluation board schematics and layouts are shown in Fig-
ures 7-9. These evaluation boards are built for dual- sup-
ply operation. Follow these steps to use the board in a
single-supply application:
1. Short -Vs to ground.
2. Use C3 and C4, if the -VS pin of the amplifier is not
directly connected to the ground plane.
