Description

The KH600 is the first amplifier to combine differential input

inputs and outputs are 100

Ω differential (50Ω single ended).

The KH600 operates from ±5V supplies and offers a fixed

gain of 14dB (5V/V).

The KH600 also offers optional supply current, differential

output offset voltage, and common mode offset voltage

adjustments.

The KH600 is constructed using Cadeka's in-house thin film

resistor/bipolar transistor technology. The KH600 is available

in a 12-pin TO-8 package.
