High Speed, Low Noise Differential Driver
The AD8620 is a perfect candidate as a low noise differential
driver for many popular ADCs. There are also other applica-
tions (such as balanced lines) that require differential drivers.
The circuit of Figure 70 is a unique line driver widely used in
industrial applications. With ±13 V supplies, the line driver can
deliver a differential signal of 23 V p-p into a 1 kΩ load. The
high slew rate and wide bandwidth of the AD8620 combine to
yield a full power bandwidth of 145 kHz while the low noise
front end produces a referred-to-input noise voltage spectral
density of 6 nV/√Hz. The design is a balanced transmission system
without transformers, where output common-mode rejection of
noise is of paramount importance. Like the transformer-based
line driver applications without changing the circuit gain of 1.
This allows the design to be easily set to noninverting, inverting,
or differential operation.
