Product Introduction

Overview

The AFE5805ZCF from Texas Instruments is a fully integrated, 8-channel analog front-end (AFE) device specifically designed for ultrasound systems. It combines a low-noise amplifier (LNA), a voltage-controlled attenuator (VCA), a programmable gain amplifier (PGA), a low-pass filter (LPF), and a 12-bit analog-to-digital converter (ADC) in a single package. This device is optimized for low power consumption and small size, making it suitable for portable ultrasound systems.
