Product details
Overview
MCP37D11-80E/TE from Microchip Technology is a 80 Msps, 12-bit pipelined analog-to-digital converter with integrated 8-channel MUX, 500 MHz input bandwidth, and configurable digital signal post-processing (DSPP) including DDC, FDR, NSR, and CW beamforming. It operates across -40°C to +125°C, supports dual LVDS/CMOS output formats, and delivers 70.9 dBFS SNR at 15 MHz input - ideal for automotive radar and ultrasound imaging systems.
For engineers reviewing the MCP37D11-80E/TE datasheet, MCP37D11-80E/TE pinout, MCP37D11-80E/TE application, or MCP37D11-80E/TE equivalent, key selection criteria include octal-channel sampling synchronization via AutoSync, AEC-Q100 Grade 1 qualification, embedded decoupling in TFBGA-121, and real-time per-channel gain/phase/offset adjustment for beamforming.
Technical Context
The MCP37D11-80E/TE implements a high-speed pipelined ADC core with on-chip PLL clock generation and duty-cycle correction. Its DSPP engine enables fractional delay recovery (FDR) for time-aligned multi-channel sampling and noise-shaping requantizer (NSR) to boost SNR beyond 12-bit limits within user-defined bands.
It features harmonic distortion correction (HDC), DAC noise cancellation (DNC), and dynamic element matching (DEM) for stable linearity across temperature. The device supports programmable full-scale input range up to 2.975 VP-P, differential clock inputs (CLK±), and SPI-configurable registers for all operational modes including Standby (79 mW) and Shutdown (22 mW).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes; guarantees monotonicity and deterministic code transitions. |
| Sample Rate | 80 Msps single-channel; scales to 10 Msps per channel in octal mode - enables synchronized wideband acquisition. |
| SNR @ 15 MHz | 70.9 dBFS typical; improves to 77.2 dBFS with NSR enabled - directly enhances dynamic range in narrowband RF applications. |
| SFDR @ 15 MHz | 92.2 dBc typical; suppresses spurious content critical for spectral purity in radar/Lidar digitization. |
| Input Bandwidth | 500 MHz - supports direct RF sampling of L-band and S-band signals without external IF stages. |
| Power Dissipation | 229 mW (core only); 248 mW (CMOS output); 311 mW (LVDS output) - enables thermal-aware system partitioning. |
| Supply Voltages | Analog: 1.2V/1.8V; Digital: 1.2V/1.8V - supports mixed-voltage SoC interfacing and low-power operation. |

Pinout & Package
Package: TFBGA-121, 8 mm × 8 mm × 1.08 mm, 0.65 mm ball pitch, lead-free, with embedded decoupling capacitors on REF0/REF1/VBG pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN0+ / AIN0− | Differential analog input channel 0 | High-impedance, 500 MHz bandwidth inputs; require matched PCB routing for optimal SFDR. |
| CLK+ / CLK− | Differential clock input | Accepts 80–250 MHz LVPECL-compatible signals; internal duty-cycle correction reduces timing skew. |
| DCLK+ / DCLK− | DDR LVDS output clock | Provides source-synchronous timing for LVDS data capture; phase adjustable via register control. |
| Q0/Q0− to Q11/Q5+ | Parallel digital output (CMOS or DDR LVDS) | 12-bit data multiplexed across 6 differential pairs in LVDS mode; supports even-bit-first default timing. |
| SDIO / SCLK / CS | SPI interface | Configures all DSPP features, calibration modes, and power states; supports daisy-chain programming of multiple devices. |
| SYNC / SLAVE | AutoSync master/slave control | Enables deterministic inter-device sampling alignment without external clock distribution networks. |
| VCM / VCMIN+ | Common-mode reference | VCM outputs 900 mV; VCMIN+ and VCMIN− must be shorted to enable auto-calibration - eliminates external bias components. |
| CAL / OVR+ / OVR− | Status and monitoring outputs | CAL indicates calibration completion; OVR flags analog overrange before data output - enables real-time signal integrity monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Wave (CW) Beamforming | Per-channel phase/gain/offset adjustment in octal mode enables real-time ultrasound Doppler and phased-array radar processing without FPGA offload. |
| Fractional Delay Recovery (FDR) | Digitally corrects sampling time misalignment between channels - achieves sub-picosecond synchronization for coherent multi-channel acquisition. |
| Noise-Shaping Requantizer (NSR) | Reshapes quantization noise out of band, improving SNR by up to 6.3 dB within selected frequency windows - extends effective resolution beyond 12 bits. |
| Digital Down-Conversion (DDC) | On-chip complex mixing and decimation - replaces external mixers and filters in IF-sampling architectures, reducing BOM and layout complexity. |
| Built-in Calibration Algorithms | HDC, DNC, DEM, and flash error correction maintain INL ≤ ±0.125 LSb and DNL ≤ ±0.03 LSb across temperature and lifetime - eliminates field recalibration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed pipeline ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9628BCPZ-80 | 12-bit, 80 Msps, JESD204B output; no embedded DSPP; requires external FPGA for beamforming or DDC. | Targets JESD204B-based SoC/FPGA platforms; lacks on-chip FDR/NSR/CW beamforming. | Select when system already uses JESD204B infrastructure and DSPP is implemented externally. |
| MCP37D21-80E/TE | 14-bit resolution, same pinout and DSPP feature set; higher ENOB (12.1 bits) but lower max sample rate per channel in multi-channel mode due to increased processing load. | Better suited for high-fidelity test equipment requiring >72 dBFS SNR; same automotive qualification and package. | Select when absolute linearity and SNR outweigh channel count or power constraints. |
Compared with AD9628BCPZ-80, the MCP37D11-80E/TE integrates DSPP functions that reduce FPGA resource usage and latency; compared with MCP37D21-80E/TE, it trades 2-bit resolution for lower power and higher effective channel throughput in octal mode.

FAQ
What is the maximum analog input frequency supported by the MCP37D11-80E/TE?
The MCP37D11-80E/TE supports an analog input bandwidth of 500 MHz (-3 dB point), enabling direct sampling of RF signals up to S-band frequencies. This specification is measured with -3 dBFS input amplitude and applies across the full operating temperature range of -40°C to +125°C. The device maintains 70.9 dBFS SNR and 92.2 dBc SFDR at 15 MHz input, with performance validated per Microchip's DS20006381A datasheet.
Does the MCP37D11-80E/TE support simultaneous sampling across all eight analog input channels?
Yes, the MCP37D11-80E/TE supports true simultaneous sampling across all eight channels in octal mode using its built-in Fractional Delay Recovery (FDR) feature. FDR digitally corrects sampling instance differences between channels, making all inputs appear time-aligned. This capability is essential for coherent beamforming in radar and ultrasound applications and is confirmed in the device's functional description and DSPP section of DS20006381A.
How does the Noise-Shaping Requantizer (NSR) improve performance in the MCP37D11-80E/TE?
The NSR in the MCP37D11-80E/TE reshapes quantization noise to push energy outside the band of interest, improving SNR by up to 6.3 dB within user-defined windows - e.g., 77.2 dBFS at 4 MHz with NSR Filter #63. This extends effective resolution beyond 12 bits without degrading SFDR, and is fully configurable via SPI registers. Performance data is documented in Table 2-1 and Figures 3-13 through 3-18 of DS20006381A.
Is the MCP37D11-80E/TE pin-compatible with other members of the MCP37Dx1-80 family?
Yes, the MCP37D11-80E/TE is pin-to-pin compatible with MCP37D21-80E/TE and MCP37D31-80E/TE, as explicitly stated in the "MCP37Dx1-80 Family Comparison" table (Note 1) of DS20006381A. This allows drop-in resolution upgrades (12→14→16-bit) without PCB redesign, provided power delivery and thermal management accommodate higher dissipation in higher-resolution variants.
What power-saving modes does the MCP37D11-80E/TE offer, and how are they controlled?
The MCP37D11-80E/TE offers Standby (79 mW) and Shutdown (22 mW) modes, both controlled via SPI register Address 0x00 bits <4:3> (Standby) and <7,0> (Shutdown). In Standby, most circuits remain active but sampling halts; in Shutdown, bias currents are cut and CAL pin goes low. These modes are detailed in Section 2.2 and Table 2-1 of DS20006381A, with timing and sequencing requirements specified for reliable entry/exit.
