DIFFERENTIAL VIDEO AMPLIFIER
• Adjustable Gain to 400 (Typ)
• No Frequency Compensation Required
• Low Noise . . . 3-mV V
n
(Typ)
This device is a monolithic two-stage video amplifier
with differential inputs and differential outputs. It
features internal series-shunt feedback that provides
wide bandwidth, low phase distortion, and excellent
gain stability. Emitter-follower outputs enable the
device to drive capacitive loads. All stages are
current-source biased to obtain high common-mode
and supply-voltage rejection ratios.
The differential gain is typically 400 when the gain
adjust pins are connected together, or amplification
may be adjusted for near 0 to 400 by the use of a
single external resistor connected between the gain
adjustment pins A and B. No external
frequency-compensating components are required for
any gain option.
The device is particularly useful in magnetic-tape or
disk-file systems using phase or NRZ encoding and
in high-speed thin-film or plated-wire memories. Other
SYMBOL
applications include general-purpose video and pulse
amplifiers.
The device achieves low equivalent noise voltage
through special processing and a new circuit layout
incorporating input transistors with low base
resistance.
The TL592B is characterized for operation from 0 ° C
to 70 ° C.
