The AFE5401-EP is an analog front-end (AFE), targeting applications where the level of integration is critical. The device includes four channels, with each channel comprising a low-noise amplifier (LNA), a programmable equalizer (EQ), a programmable gain amplifier (PGA), and an antialias filter followed by a high-speed, 12-bit, analog-to-digital converter (ADC) at 25MSPS per channel.
Each of the four differential input pairs are amplified by an LNA and are followed by a PGA with a programmable gain range from 0dB to 30dB. An antialias, low-pass filter (LPF) is also integrated between the PGA and ADC for each channel.
Each LNA, PGA, and antialiasing filter output is differential (limited to 2VPP). The antialiasing filter drives the on-chip, 12-bit, 25MSPS ADC. The four ADC outputs are multiplexed on a 12-bit, parallel, CMOS output bus.
The device is available in a 9mm × 9mm, VQFN-64 package and is specified over a temperature range of –40°C to +125°C. For more information, contact AFE5401_info@list.ti.com.
