General Description
The KH600 is the first amplifier to combine differential
input and output with a bandwidth of DC-1GHz at
2Vpp. The inputs and outputs are 100differential
(50single 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.

Supply Current
The KH600 draws supply current from the 2 Vs pins as
well as the 3 Vb pins. Under Standard Conditions, the
total supply current is typically 89mA. Changing the
voltages on the bias voltage pins will change their
respective supply currents as shown in Figures 5 and 6.

Figure 5: Vb Supply Currents vs +Vb1
Changing the voltage on the +Vb1 pin will alter the
supply current for +Vb1 only, +Vb2 and -Vb stay constant
at typically 11mA and 22mA respectively. See Figure 5.
The same principle applies for +Vb2. And Figure 6
illustrates the effect of changing -Vb.

Power Dissipation
The KH600 runs at constantpower, which may be
calculated by (Total Is)(Vs (-Vs)). Under standard
operating conditions, the power is 890mW. The power
dissipated in the package is completely constant,
independent of signal level. In other words, the
KH600 runs class A.
Power Supply Rejection Ratio (PSRR)
The KH600 has 5 supply pins, +Vs, -Vs, +Vb1, +Vb2,
and -Vb. All of these sources must be considered
when measuring the PSRR. Figure 7 shows the
response of +Vs and -Vs, looking at OUT2. +Vs and -Vs
have the same effect on OUT1.

Figure 7: ±Vs PSRR
Figure 8 shows the response of OUT1 and OUT2 when
+Vb1 changes. The PSRR of the Vb pins is bad, which
means that they have a large effect on the response
of the KH600 when their voltages are changed. This
is the desired effect of the bias voltage pins. As Figure 8
indicates, changing +Vb1 has a greater effect on OUT1
than it does on OUT2. Changing +Vb1 has a direct
effect on OUT1. Changing +Vb2 has a direct effect on
OUT2. See the Trimming Differential Output Offset
Voltage section for more details.
