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.

AFE5401-Q1EVM — AFE5401 평가 모듈
AFE5401 평가 모듈(EVM)은 다양한 신호, 클록, 레퍼런스, ADC 출력 형식을 에 대해 AFE5401 통합 신호 체인 쿼드 채널 AFE(아날로그 프론트 엔드)를 평가하는 플랫폼을 제공합니다.
AFE5401-Q1EVM 평가를 위해 TSW1400EVM(구형)이 필요합니다. TSW1400EVM이 이미 있는 경우가 아니면 AFE5401-Q1EVM을 구매하지 않는 것이 좋습니다.
