The µA733 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 µA733C is characterized for operation from 0°C to 70°C; the µA733M is characterized for operation over the full military temperature range of 55°C to 125°C.
● 200-MHz Bandwidth
● 250-k Input Resistance
● Selectable Nominal Amplification of 10, 100, or 400
● No Frequency Compensation Required
●The µA733M is obsolete and no longer supplied.
