D 200-MHz BandwidthD 250-k Input ResistanceD Selectable Nominal Amplification of 10,

Fairchild uA733C and uA733M

description

The uA733 is a monolithic two-stage videoamplifier with differential inputs and differentialoutputs.

Internal series-shunt feedback provides widebandwidth, low phase distortion, and excellentgain stability. Emitter-follower outputs enable thedevice to drive capacitive loads, and all stages arecurrent-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 externalcomponents, or amplification may be adjustedfrom 10 V/V to 400 V/V by the use of asingle external resistor connected between 1Aand 1B. No external frequency-compensatingcomponents are required for any gain option.

The device is particularly useful in magnetic-tapeor disc-file systems using phase or NRZ encodingand in high-speed thin-film or plated-wire

memories. Other applications include general-purpose video and pulse amplifiers where widebandwidth, low phase shift, and excellent gainstability are required.

The uA733C is characterized for operation from 0 C to 70 C; the uA733M is characterized for operation overthe full military temperature range of 55 C to 125 C.
