THS7320IYHCT

Overview

The THS7320IYHCT is a triple-channel video amplifier from Texas Instruments, designed for composite and component video signal processing. It integrates three independent amplifiers with fixed gain of 4 V/V and built-in low-pass filters. The device operates within a supply voltage range of 4.5 V to 5.5 V, consuming typical supply current of 18 mA per channel. It supports differential inputs and outputs, ensuring high common-mode rejection. The operational temperature range extends from -40°C to +85°C. Packaged in a compact DSBGA-9 format, it facilitates surface-mount assembly for space-constrained applications.

Procurement Notes

Verify the complete part number including the 'T' suffix, which indicates tape-and-reel packaging, against the specific order quantity requirements. Confirm the manufacturer is Texas Instruments to ensure authenticity. Check the datasheet for the latest mechanical outline drawing to verify the DSBGA-9 footprint dimensions before finalizing the PCB layout. Ensure the design accommodates the specified thermal characteristics for the intended operating environment.

Selection Notes

Select this component when a triple-channel solution with integrated filtering is required for video paths. The fixed 4 V/V gain simplifies circuit design by eliminating external feedback resistors. Consider the DSBGA-9 package size for board space limitations. Verify that the single-supply operation aligns with the system power architecture. Ensure the differential I/O capability matches the source and destination interface requirements.

Part Context

The THS7320 belongs to the THS7320 family of video amplifiers. It is distinct from other TI video products by its specific integration of three channels with fixed gain and filtering in a small footprint. This series targets applications requiring multiple video signal paths without complex external component networks. The 'I' designation typically indicates an industrial temperature grade.

Replacement Considerations

Consult official substitution guides for compatible devices. Verify pin-to-pin compatibility if replacing with similar triple-channel video amplifiers. Ensure electrical parameters such as bandwidth, slew rate, and gain match the original design requirements.
