LMH6734MQX/NOPB

Video Amps And Modules Overview

The LMH6734 is an obsolete single-supply, ultra-high-speed, triple selectable gain buffer manufactured by Texas Instruments. It utilizes a current feedback architecture to provide gains of -1, +1, and +2. The device operates on a supply range of 3V to 12V (single) or ±1.5V to ±6V (split). Key electrical parameters include a 925 MHz unity-gain bandwidth, a 650 MHz small-signal bandwidth at AV = +2, and a slew rate of 3750 V/µs. It features low supply current consumption of 5.5 mA per op amp and an input noise voltage density of 2.1 nV/√Hz.

Video Amps And Modules Feature Summary

• Selectable closed-loop gain configuration supporting -1, +1, and +2 V/V settings via internal feedback resistors.
• Ultra-high-speed performance with a 925 MHz unity-gain bandwidth and 3750 V/µs slew rate for high-resolution video systems.
• Low power consumption with a typical supply current of 5.5 mA per amplifier channel.
• Integrated disable pins for individual channel control to reduce power during standby.

Video Amps And Modules Applications

• HDTV component video driver
• CAT5 component video driver
• High resolution projector signal processing
• Wide dynamic range intermediate frequency amplifiers

Video Amps And Modules Procurement Notes

Verify the obsolete status of this component before design finalization. Confirm that the specific ordering suffix matches the required package type. Review the manufacturer's standard warranty terms regarding availability and critical application usage. Ensure alternative components are identified if long-term supply continuity is required for the project lifecycle.

Video Amps And Modules Selection Notes

Select this device for applications requiring precise gain selection without external resistor matching errors. The internal RF and RG resistors ensure stable gain accuracy over temperature. Consider the 16-pin SSOP package constraints for board layout. Evaluate the need for series output resistors when driving capacitive loads to prevent oscillation.

Video Amps And Modules Part Context

This part belongs to the LMH67xx family of high-speed operational amplifiers designed for video and wideband signal processing. Unlike voltage feedback amplifiers, this current feedback device offers bandwidth independent of gain magnitude. The triple-channel configuration allows for compact multi-signal processing solutions in space-constrained designs.
