SN761663DGKR

Video Amps And Modules Overview

The SN761663DGKR is a low-distortion automatic gain control (AGC) amplifier designed for TV tuner systems in digital TVs, digital CATV, and set-top boxes. It features three stages of controlled-gain amplification followed by a fixed-gain output amplifier. The device operates on a single 5-V power supply and is housed in an 8-pin MSOP package. Key electrical characteristics include a maximum gain of 64 dB at VAGC = 3 V, a minimum gain of -4 dB at VAGC = 0 V, and a gain control range of 67 dB. The typical supply current is 23 mA.

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix 'DGKR' to confirm the tape-and-reel quantity of 2500 units. Confirm that the component status is listed as active for new designs. Ensure the package type matches the required surface-mount footprint. Check RoHS compliance details if environmental regulations apply to the manufacturing process.

Video Amps And Modules Selection Notes

Select this component when designing tuner front-ends requiring precise gain adjustment via a voltage-controlled input. The device is suitable for applications needing a high dynamic range and low intermodulation distortion. Consider the 8-pin MSOP package constraints for PCB layout. Verify that the operating temperature range meets the system requirements.

Video Amps And Modules Part Context

This part belongs to Texas Instruments' lineup of analog signal processing components specifically tailored for video and RF applications. The SN761663 series addresses the need for integrated gain control solutions in consumer electronics. It replaces discrete amplifier configurations by combining multiple gain stages into a single monolithic IC.
