VCA5807PZP

Overview

The VCA5807PZP is a fully integrated, eight-channel voltage-controlled amplifier (VCA) designed for high-performance and compact ultrasound systems. It integrates a complete time gain control imaging path and a continuous wave Doppler path within a single device. The component operates on supply voltages ranging from 3.15 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. It utilizes a 100-pin HTQFP package measuring 14 mm by 14 mm.

Feature Summary

• Integrates low-noise amplifiers, programmable gain amplifiers, and passive CW mixers for comprehensive signal processing
• Provides selectable power-to-noise optimization modes to enhance system performance flexibility
• Features ultra-low noise voltage control attenuators with extended attenuation ranges
• Includes third-order linear phase low-pass filters configurable for various frequency applications

Applications

• High-end ultrasound imaging systems requiring small form factors
• Portable ultrasound devices needing optimized power consumption
• Continuous wave Doppler signal processing paths
• Sonar applications supporting low-frequency signal processing below 100 kHz

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status through current manufacturer datasheets before procurement. Check for any recent product change notices regarding packaging or material composition updates.

Selection Notes

Select this component when designing systems requiring integrated multi-channel analog front-ends. Ensure the application benefits from the specific noise-power trade-offs offered by the selectable modes. Verify that the 100-pin HTQFP footprint aligns with the PCB layout constraints and thermal management requirements of the target design.
