UA733CNS

Overview

The UA733CNS is a monolithic two-stage differential video amplifier manufactured by Texas Instruments. It features selectable nominal amplification of 10 V/V, 100 V/V, or 400 V/V without external components. The device operates within a temperature range of 0°C to +70°C and consumes 16 mA of supply current. It provides a 200-MHz bandwidth and includes internal series-shunt feedback for wide bandwidth and low phase distortion. The unit is housed in a PDIP-14 package with a maximum power dissipation of 500 mW.

Feature Summary

• Monolithic two-stage design with differential inputs and outputs
• Selectable fixed gain options of 10, 100, or 400 V/V
• Internal series-shunt feedback ensures wide bandwidth and stability
• Emitter-follower outputs enable capacitive load driving

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 suffix 'NS' against official Texas Instruments documentation to confirm package details and availability. Ensure the component meets the required commercial temperature range of 0°C to +70°C. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and compliance with RoHS standards before procurement.

Selection Notes

Select this component when a differential video amplifier with high bandwidth and low phase distortion is required. It is suitable for applications needing fixed gain settings without external compensation components. Consider the 16 mA supply current and 500 mW power dissipation limits during thermal management planning. Verify that the PDIP-14 package fits the available board space.

Part Context

The UA733CNS belongs to the UA733 series of differential video amplifiers from Texas Instruments. This series is designed for high-speed signal processing where gain stability and wide bandwidth are critical. The 'C' designation indicates the commercial temperature grade, while 'NS' typically denotes the specific plastic DIP packaging variant used in through-hole applications.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the UA733 family. Verify that any replacement maintains the 200-MHz bandwidth and selectable gain characteristics. Ensure the alternative component supports the same operating voltage and temperature range requirements.
