Overview
The UA733M/BCA is a monolithic two-stage differential video amplifier manufactured by Rochester Electronics. It features differential inputs and outputs with internal series-shunt feedback for wide bandwidth and low phase distortion. The device offers selectable nominal voltage gains of 10 V/V, 100 V/V, or 400 V/V without external components, or adjustable gain via a single resistor. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- Monolithic two-stage architecture with differential input and output stages
- Internal series-shunt feedback ensures wide bandwidth and excellent gain stability
- Emitter-follower outputs enable driving of capacitive loads
- All stages are current-source biased for high common-mode rejection
Applications
- Magnetic-tape systems using phase or NRZ encoding
- Disc-file systems utilizing phase or NRZ encoding
- High-speed thin-film memories
- Plated-wire memory applications
- General-purpose video amplification requiring wide bandwidth
Procurement Notes
Verify the specific suffix BCA against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the operating environment falls within the specified military temperature range of -55°C to +125°C. Confirm that the selected gain configuration aligns with system requirements before integration.
Selection Notes
Select this component when differential signaling is required for video or pulse amplification. It is suitable for applications demanding high common-mode rejection and the ability to drive capacitive loads directly. Consider the fixed gain options or single-resistor adjustability for circuit simplicity. Verify thermal management capabilities for the upper temperature limit.
Part Context
Rochester Electronics provides this part as a sourced component from the original Texas Instruments manufacturing line. The UA733 family is established for high-speed analog signal processing. This specific variant supports extended industrial and military temperature ranges compared to commercial grades.
Replacement Considerations
Direct substitutes include the UA733C for commercial temperature ranges. Other compatible parts in the UA733 series may offer similar electrical performance but require verification of package dimensions and pin configurations.
