TX7516ALH

Specialized ICS Overview

The TX7516ALH is a high-performance, highly integrated transmitter solution designed for ultrasound imaging systems. It features 16-channel five-level pulsers capable of generating output voltages up to ±100 V with a maximum current of 2 A (supporting 4 A mode). The device integrates active transmit/receive switches and an on-chip beamformer with per-channel pattern control and delay profiles. Communication is managed via a high-speed 400 MHz LVDS serial interface or a 50 MHz CMOS serial interface. It operates within a temperature range of 0°C to +70°C and is housed in a 144-pin FC-BGA package measuring 10 mm × 10 mm.

Specialized ICS Procurement Notes

Verify the specific ordering suffix 'ALH' corresponds to the FCCSP-144 package variant when sourcing. Confirm that the component status is listed as Active Production Data. Ensure compliance with moisture sensitivity level requirements during storage and handling procedures prior to soldering.

Specialized ICS Selection Notes

Select this component for designs requiring integrated transmit beamforming and high-voltage excitation for piezoelectric transducers. Evaluate the 144-pin FC-BGA footprint constraints against available PCB real estate. Consider the 400 MHz interface speed for rapid profile updates if low latency is critical for the application timing.

Specialized ICS Part Context

This part belongs to the Texas Instruments TX7516 series of specialized analog front-end transmitters. It is specifically engineered to replace discrete pulser and switch solutions by consolidating functionality into a single integrated circuit, thereby reducing the external component count required for floating supplies and bias generation.

Specialized ICS Replacement Considerations

Direct pin-to-pin replacements are not explicitly documented in the provided datasheet. Designers should evaluate other members of the TX7516 family or TI's broader ultrasound AFE portfolio for potential alternatives based on channel count and package compatibility.
