General Description
The KH600 is the first amplifier to combine differential
input and output with a bandwidth of DC-1GHz at
2V_pp. The inputs and outputs are 100Ω 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, differ-
ential output offset voltage, and common mode off-
set voltage adjustments.
The KH600 is constructed using Fairchild's in-house
thin film resistor/bipolar transistor technology. The
KH600 is available in a 12-pin TO8 package.

The KH600 includes 50Ω resistors from each
input to ground (resulting in a differential input
impedance of 100Ω).
