Texas Instruments  AFE5401TRGCTQ1

The AFE5401-Q1 is an analog front-end (AFE), targeting applications where the level ofintegration is critical. The device includes four channels, with each channel comprising alow-noise amplifier (LNA), a programmable equalizer (EQ), a programmable gain amplifier (PGA), andan antialias filter followed by a high-speed, 12-bit, analog-to-digital converter (ADC) at 25 MSPSper channel.

Each of the four differential input pairs are amplified by an LNA and are followed by aPGA with a programmable gain range from 0 dB to 30 dB. An antialias, low-pass filter (LPF) is alsointegrated 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, 25-MSPS ADC. Thefour ADC outputs are multiplexed on a 12-bit, parallel, CMOS output bus.

The device is available in a 9-mm × 9-mm, VQFN-64 package and is specified over atemperature range of –40°C to +105°C. For more information, contactAFE5401_info@list.ti.com.
