MCP37D31T-200I/TE

Analog To Digital Converters (ADC) Overview

The MCP37D31T-200I/TE is a 16-bit, 200 Msps pipelined Analog-to-Digital Converter (ADC) from Microchip Technology. It features an integrated Digital Down-Converter (DDC) and Continuous Wave (CW) beamforming capabilities. The device supports up to eight differential input channels via an internal multiplexer, providing a sample rate of 200 Msps in single-channel mode or 25 Msps per channel in octal mode. Typical performance includes a Signal-to-Noise Ratio (SNR) of 74.7 dBFS and a Spurious-Free Dynamic Range (SFDR) of 90 dBc at 15 MHz input. Power consumption is 490 mW with LVDS I/O at full speed. It operates on 1.2V and 1.8V supplies and is available in TFBGA-121 and VTLA-124 packages.

Analog To Digital Converters (ADC) Feature Summary

• Digital Signal Post-Processing: Includes DDC with I/Q output, CW beamforming for octal-channel mode, decimation filters, and Fractional Delay Recovery (FDR).
• High Performance: Achieves 74.7 dBFS SNR and 90 dBc SFDR at 200 Msps with built-in calibration algorithms like Harmonic Distortion Correction (HDC) and DAC Noise Cancellation (DNC).
• Flexible Input and Output: Supports up to 8 differential analog inputs with selectable full-scale range up to 2.975 VP-P. Outputs available as Parallel CMOS, DDR LVDS, or Serialized DDR LVDS.
• Low Power Operation: Consumes 490 mW at 200 Msps with LVDS; reduces to 144 mW in Standby and 28 mW in Shutdown modes.

Analog To Digital Converters (ADC) Applications

• Cellular Base Stations
• Lidar and Radar Systems
• Ultrasound and Sonar Imaging
• Communication Instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type upon ordering, as the MCP37D31-200 family is offered in TFBGA-121 (AEC-Q100 qualified, -40°C to +125°C) and VTLA-124 (-40°C to +85°C). Confirm that the specific suffix corresponds to the desired temperature grade and automotive qualification status. Ensure the design accounts for the embedded decoupling capacitors present in the TFBGA package for reference pins.

Analog To Digital Converters (ADC) Selection Notes

Select the MCP37D31T-200I/TE when digital down-conversion and CW beamforming are required, distinguishing it from the non-D 'MCP37231' variant. Choose this part over lower-resolution models if 16-bit precision is necessary for the application. Consider the VTLA-124 package if automotive qualification is not needed, or the TFBGA-121 for extended temperature ranges and embedded decoupling. Verify SPI address pin configurations (ADR0/ADR1) for multi-device synchronization.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MCP37D31/21-200 family, which shares pin compatibility within the same package type. It is distinguished from the MCP37231-200 by the inclusion of Digital Down-Conversion (DDC) and Continuous Wave (CW) Beamforming features. The 'T' suffix indicates tape and reel packaging, while 'I' denotes the industrial temperature range. The device is designed for high-speed data acquisition systems requiring low power and high dynamic performance.

Analog To Digital Converters (ADC) Replacement Considerations

Devices within the same package type are pin-to-pin compatible. The MCP37D21-200 (14-bit) and MCP37D11-200 (12-bit) are functional substitutes if lower resolution is acceptable. For applications not requiring DDC or beamforming, the MCP37231-200 (16-bit) may be used. Ensure the replacement part supports the required output interface (CMOS/LVDS) and operating temperature range.
