Description
Demonstration circuit 2496A features the LTC6432-15
differential ADC Driver/IF Amplifier. The
a fixed power gain of 15.9dB and works from 100kHz
to 1400MHz. It is part of the high linearity LTC643X-YY
amplifier series.
As a differential amplifier, the LTC6432-15 offers flat gain
and impressive linearity from 100kHz to 1GHz using a
single output bias network. Since high fidelity differen-
tial test equipment is lacking, the DC2496A offers single
100kHz to 1000MHz Differential
ADC Driver/IF/RF Amplifier
ended inputs and outputs so that the LTC6432-15 perfor-

mance may be evaluated with standard test equipment.
®
The native LTC6432-15 has 100Ω differential source and
load impedances, so the demo circuit uses 2:1 transform-
ers to convert the differential input/output impedances to
50Ω single-ended impedance.
