AFE5808ZCF

Analog Front End (AFE) Overview

The AFE5808ZCF is an eight-channel analog front-end (AFE) integrated circuit manufactured by Texas Instruments, designed for ultrasound applications. It integrates low-noise amplifiers, programmable gain amplifiers, and 14-bit analog-to-digital converters with a maximum sampling rate of 65 MS/s. The device operates on a supply voltage ranging from 1.7 V to 1.9 V and features a serial SPI interface for configuration. Packaged in a 135-pin nFBGA, it delivers a signal-to-noise ratio of 77 dBFS and a gain error of +/-0.5 dB. The component functions within a temperature range of 0°C to +70°C.
