UA733CNSR

Overview

The UA733CNSR is a monolithic two-stage video amplifier manufactured by Texas Instruments, housed in a 14-pin SOP (NS) 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. It operates within a temperature range of 0°C to 70°C and requires no external frequency compensation components.

Feature Summary

• Monolithic two-stage architecture providing wide bandwidth and low phase distortion through internal series-shunt feedback.
• Differential input and output configuration with emitter-follower outputs capable of driving capacitive loads.
• Selectable fixed differential amplification of 10, 100, or 400 V/V without external components.
• Adjustable amplification from 10 V/V to 400 V/V using a single external resistor between gain adjustment pins.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'SR' corresponds to the tape-and-reel packaging format as documented in the manufacturer's official Package Option Addendum. Confirm that the SOP (NS) package designation aligns with your printed circuit board layout requirements. Ensure the commercial temperature range specification meets your operational environmental constraints before finalizing procurement.

Selection Notes

Select this component when differential signal processing with high bandwidth is required. The UA733CNSR is suitable for applications needing adjustable gain without external compensation networks. Consider the 14-pin SOP package dimensions for space-constrained designs. Evaluate the supply current and power dissipation characteristics against your thermal management capabilities.

Part Context

This part belongs to the µA733 family of differential video amplifiers. The 'C' suffix indicates the commercial temperature grade (0°C to 70°C), while the 'NS' suffix denotes the Small Outline Package. The 'SR' suffix specifies the reel packaging quantity. This family is designed for high-speed analog signal processing tasks.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs if considering alternative manufacturers, as pinouts and electrical characteristics may differ significantly.

FAQ

How is the gain adjusted on the UA733CNSR?

Gain can be set to fixed values of 10, 100, or 400 V/V by connecting specific gain-adjust pins. Alternatively, continuous adjustment from 10 V/V to 400 V/V is achieved by placing a single external resistor between pins 1A and 1B.

Does the UA733CNSR require external frequency compensation?

No, the device does not require external frequency-compensating components for any gain option due to its internal series-shunt feedback design.
