Overview
The AFE58JD32ZBV, produced by Texas Instruments, is a highly integrated 32-channel analog front-end (AFE) solution specifically designed for ultrasound systems. This device is optimized for high performance, low power consumption, and compact size, making it ideal for medical ultrasound applications. The AFE58JD32ZBV is realized through a multichip module (MCM) consisting of three dies: two voltage-controlled amplifier (VCA) dies and one analog-to-digital converter (ADC) die. Each VCA die has 16 channels, and the ADC die converts all 32 channels, providing a comprehensive analog-to-digital conversion solution.
