AD12401-400JWS

Overview

The AD12401-400JWS is a 12-bit, 400 MSPS analog-to-digital converter (ADC) featuring transformer-coupled analog input and digital post-processing for enhanced spurious-free dynamic range (SFDR). It operates with a 3.7 V analog supply and 3.3 V/1.5 V digital supplies. The device provides an SNR of 63 dBFS at 128 MHz and an SFDR of 70 dBFS at 128 MHz. It supports single-ended or differential ENCODE signals and outputs two's complement data via LVDS levels. The module includes high gain grade configuration and wideband AC-coupled input signal conditioning.

Feature Summary

• Up to 400 MSPS sample rate with 12-bit resolution
• SNR of 63 dBFS @ 128 MHz and SFDR of 70 dBFS @ 128 MHz
• Transformer-coupled analog input with wideband AC-coupling
• LVDS output levels with single-ended or differential ENCODE support

Applications

• Communications test equipment
• Radar and satellite subsystems
• Phased array antennas and digital beams
• Multichannel, multimode receivers
• Secure communications and broadband systems

Procurement Notes

Verify the specific ordering suffix '400JWS' corresponds to the 400 MSPS conversion rate and high gain grade configuration as defined in the manufacturer's ordering guide. Confirm that the required power supplies (3.7 V analog, 3.3 V and 1.5 V digital) are available for the enclosed module package. Ensure thermal management meets the case temperature range requirements of 0°C to 60°C.

Selection Notes

Select the AD12401-400JWS when high gain mode is required, distinguished from the KWS variant by grounding the H/L_GAIN pin versus pulling it up to 3.3 V. The JWS grade specifies full-scale input voltage ranges and gain error tolerances distinct from other grades. Verify that the system can accommodate the 3.7 V, 3.3 V, and 1.5 V supply rails and the enclosed module form factor dimensions.

Part Context

The AD12401 series utilizes proprietary Advanced Filter Bank (AFB™) digital post-processing from V Corp Technologies, Inc., to enhance dynamic performance. The device integrates time-interleaved ADC channels with digital correction mechanisms. It is designed for wideband carrier systems requiring outstanding dynamic performance without external references or complex signal conditioning circuits.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the datasheet. Contact sales for additional performance options such as sample rates greater than 400 MSPS or second Nyquist zone operation variants.
