Description

The AFE5401-Q1 includes four channels, with each channel comprising a low-noise amplifier (LNA), an optional equalizer (EQ), a programmable gain amplifier (PGA), and an antialias filter followed by a high-speed, 12-bit, analog-to-digital converter (ADC) at 25 MSPS per channel.

The four ADC outputs are multiplexed on a 12-bit, parallel, CMOS-compatible output bus. For more information, contact AFE5401_info@list.ti.com.
