Overview
The Texas Instruments AFE58JD28ZAV is a high-performance, low-power, 12/14-bit analog front-end (AFE) designed for precision data acquisition systems. This advanced AFE is particularly well-suited for applications requiring high accuracy and low noise performance, such as medical imaging, industrial control systems, and test and measurement equipment. The device is realized through a multichip module (MCM) with two dies: one voltage-controlled amplifier (VCA) die and one analog-to-digital converter (ADC) die, each with 16 channels.
