description/ordering information
The
A733 is a monolithic two-stage video amplifier with differential inputs and differential outputs. Internal
series-shunt feedback provides wide bandwidth, low phase distortion, and excellent gain stability.
Emitter-follower outputs enable the device to drive capacitive loads, and all stages are current-source biased
to obtain high common-mode and supply-voltage rejection ratios.
Fixed differential amplification of 10 V/ V, 100 V/ V, or 400 V/ V may be selected without external components,
or amplification may be adjusted from 10 V/ V to 400 V/ V by the use of a single external resistor connected
between 1A and 1B. No external frequency-compensating components are required for any gain option.
The device is particularly useful in magnetic-tape or disc-file systems using phase or NRZ encoding and in
high-speed thin-film or plated-wire memories. Other applications include general-purpose video and pulse
amplifiers where wide bandwidth, low phase shift, and excellent gain stability are required.
The
A733C is characterized for operation from 0
C to 70
C; the
A733M is characterized for operation over
the full military temperature range of -55
C to 125
C.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. This is a stress rating only, and
functional operation of the device at these or any other conditions beyond those indicated in the recommended operating conditions section of
this specification is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltage values, except differential input voltages, are with respect to the midpoint between VCC+ and VCC.
2. Maximum power dissipation is a function of TJ(max),
q
JA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) TA)/
q
JA. Operating at the absolute maximum TJ of 150
C can affect reliability.
3. The package thermal impedance is calculated in accordance with JESD 51-7.
