UA733CD

Overview

The UA733CD is a monolithic two-stage video amplifier manufactured by Texas Instruments, housed in a 14-pin SOIC package. It features differential inputs and outputs with selectable nominal amplification of 10 V/V, 100 V/V, or 400 V/V. The device provides a bandwidth of up to 200 MHz and an input resistance of 250 kΩ at the highest gain setting. Operating characteristics include a supply current of 16 mA and a power dissipation rating of 86 mW for the D package. It is characterized for operation within a temperature range of 0°C to 70°C.

Feature Summary

• Monolithic two-stage architecture with differential inputs and outputs
• Internal series-shunt feedback ensures wide bandwidth and low phase distortion
• Emitter-follower outputs enable driving of capacitive loads
• No external frequency-compensating components required

Applications

• Magnetic-tape systems using phase or NRZ encoding
• Disc-file systems utilizing phase or NRZ encoding
• High-speed thin-film or plated-wire memories
• General-purpose video and pulse amplifiers requiring wide bandwidth

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm the package type and tube quantity. Confirm that the active status aligns with current production schedules. Ensure the operating temperature range meets the environmental requirements of the target application before finalizing procurement.

Selection Notes

Select this component when differential signal processing with high bandwidth is required without external compensation. Consider the fixed gain options or single-resistor adjustability for circuit simplicity. Evaluate the thermal derating factors for the SOIC package if ambient temperatures approach the upper limit of the specified range.

Part Context

This part belongs to the UA733 family of differential video amplifiers. The 'CD' designation specifically indicates the commercial temperature grade (0°C to 70°C) and the SOIC surface-mount package. Other variants in the family include the CN for PDIP packaging and the M-grade parts for military temperature ranges.

Replacement Considerations

Direct pin-compatible replacements within the same family include the UA733CN for through-hole applications. Verify functional equivalence regarding gain settings and output drive capabilities when substituting.
