description
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. Emitterfollower outputs enable the device to drive
capacitive loads. All stages are current-source
biased to obtain high common-mode and supplyvoltage 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 applications include generalpurpose video and pulse amplifiers.
