Product details
Overview
MCP33141D-10T-E/MS from Microchip Technology is a 12-bit, 1 Msps fully differential successive approximation register (SAR) analog-to-digital converter with no missing codes, operating from 1.8V AVDD and supporting 1.7–5.5V DVIO. It delivers 73.8 dBFS SNR, ±0.07 LSB INL, and ultra-low 1.5 µA standby current, enabling high-precision data acquisition in battery-powered motor control and EV battery management systems.
For engineers reviewing the MCP33141D-10T-E/MS datasheet, MCP33141D-10T-E/MS pinout, MCP33141D-10T-E/MS application, or MCP33141D-10T-E/MS equivalent, key selection criteria include its 1 Msps throughput, differential ±5.1V input range, SPI-compatible 3-wire interface with BUSY option, on-demand self-calibration, and AEC-Q100 Grade 1 qualification for automotive use.
Technical Context
The MCP33141D-10T-E/MS implements a SAR architecture with internal clock generation independent of SCLK, enabling deterministic conversion timing. Its differential input stage supports full-scale ranges from –VREF to +VREF, with VREF configurable from AVDD to 5.1V, decoupled from analog supply constraints.
It features automatic power-up calibration (400–550 ms) and user-triggered recalibration to correct offset, gain, and linearity errors. The built-in data accumulator integrates up to 1024 samples, increasing effective number of bits (ENOB) to 18.5 bits via hardware averaging-critical for noise-sensitive measurement applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonicity and unambiguous digital output across full scale. |
| Sample Rate | 1 Msps - enables real-time capture of signals up to 500 kHz (Nyquist), suitable for fast transient monitoring in power electronics. |
| Differential Input Range | ±5.1V - supports high-voltage sensor interfaces (e.g., shunt-based current sensing) without external signal conditioning. |
| SNR / SINAD | 73.8 dBFS / 73.8 dBFS at fIN = 10 kHz - delivers >12-bit effective resolution in typical industrial signal bandwidths. |
| INL / DNL | ±0.07 LSB / ±0.05 LSB - ensures sub-LSB linearity for precision closed-loop control and calibration-critical instrumentation. |
| Supply Voltages | AVDD = 1.8V, DVIO = 1.7–5.5V - allows direct interfacing with 1.8V, 3.3V, or 5V microcontrollers without level shifters. |
| Standby Current | ~1.5 µA - extends battery life in portable test equipment and always-on monitoring nodes. |
Pinout & Package
Package: MSOP-10 (3 mm × 3 mm, exposed thermal pad), RoHS-compliant, rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN+ | Differential analog input positive | Accepts high-side input of differential pair; common-mode voltage range = 0 to VREF. |
| AIN− | Differential analog input negative | Accepts low-side input; full-scale differential swing = 2 × VREF (e.g., ±5.1V). |
| GND | Analog/digital ground reference | Single ground plane required; decoupling capacitors recommended on AVDD, DVIO, and VREF pins. |
| SDO | SPI serial data output | Three-state output; driven after CNVST falling edge; compatible with 100 MHz SCLK. |
| SCLK | SPI serial clock input | Accepts up to 100 MHz clock; timing defined per Table 1-2 (e.g., tSCLK_L ≥ 4.5 ns at DVIO ≥ 1.7V). |
| CNVST | Conversion start / chip select | Rising edge initiates sampling; falling edge releases SDO data; doubles as active-low CS in 3-wire mode. |
| SDI | SPI serial data input | Accepts recalibrate command and configuration bits; VIH/VIL thresholds scale with DVIO. |
| VREF | External reference voltage input | Set from AVDD to 5.1V; determines full-scale range and directly impacts SNR and ENOB. |
| AVDD | Analog supply voltage | Fixed 1.8V supply; powers internal SAR core, reference buffer, and analog front-end. |
| DVIO | Digital I/O supply voltage | Independent 1.7–5.5V rail; sets logic thresholds and drives SDO/SDI/SCLK I/O levels. |
Key Features
| Feature | Design Value |
|---|---|
| No latency output | Conversion result available immediately after CNVST falling edge-enables deterministic real-time control loops. |
| Built-in data accumulator | Hardware-averages up to 1024 samples to boost ENOB to 18.5 bits, reducing post-processing load on host MCU. |
| Self-calibration | Automatic at power-up (400–550 ms) and on-demand via SPI command-maintains accuracy across temperature and aging. |
| AEC-Q100 Grade 1 | Qualified for automotive applications from –40°C to +125°C junction temperature-validates reliability in under-hood environments. |
| SPI 3-wire with optional BUSY | Minimizes PCB routing; BUSY indicator (via SDI or dedicated pin on other variants) eliminates polling overhead in time-critical systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP33141D-10T-E/MNY | TDFN-10 package (3×3 mm, exposed thermal pad) vs. MSOP-10; lower θJA (68°C/W vs. 202°C/W). | Better thermal performance in high-density or high-ambient-temperature layouts; same pinout and electrical specs. | Select for improved power dissipation in compact industrial modules or automotive ECUs. |
| ADS8860IDRCT | 16-bit, 1 Msps SAR ADC (TI); higher resolution but higher power (~1.5 mA active vs. 0.66 mA), no built-in accumulator. | Used where ultimate DC precision outweighs power and feature trade-offs; lacks on-chip averaging and recalibration command. | Choose when >12-bit ENOB is mandatory and host MCU can handle raw data processing. |
Compared with MCP33141D-10T-E/MNY, the MSOP-10 variant offers identical functionality with higher thermal resistance-suitable for lower-power deployments-while ADS8860IDRCT trades integrated features for higher resolution and requires external signal conditioning and averaging logic.

FAQ
What is the maximum SPI clock frequency supported by the MCP33141D-10T-E/MS?
The MCP33141D-10T-E/MS supports an SCLK frequency up to 100 MHz under DVIO ≥ 3.3V conditions. At lower DVIO voltages (e.g., 1.7V), the maximum SCLK drops to 62.5 MHz. Timing parameters-including tSCLK_L, tSCLK_H, and tDO-are specified per DVIO level in Table 1-2 of the datasheet to ensure reliable communication.
Does the MCP33141D-10T-E/MS require an external reference voltage?
Yes, the MCP33141D-10T-E/MS requires an external reference voltage (VREF) applied to the VREF pin. VREF is configurable from AVDD up to 5.1V and directly defines the differential input full-scale range (±VREF). Internal reference is not provided; stability and noise performance of VREF directly impact SNR and THD.
How does the self-calibration function work in the MCP33141D-10T-E/MS?
The MCP33141D-10T-E/MS performs automatic self-calibration at power-up (taking 400–550 ms) to correct offset, gain, and linearity errors. Users can also issue a recalibrate command via SPI at any time-critical after environmental shifts (e.g., reference voltage settling issues) to restore optimal performance without system reset.
What is the input acquisition time and total conversion cycle time for the MCP33141D-10T-E/MS?
For the MCP33141D-10T-E/MS, input acquisition time (tACQ) is 250–490 ns and conversion time (tCNV) is 510–750 ns, resulting in a total cycle time (tCYC) of 1 µs at 1 Msps. This deterministic timing enables precise synchronization in time-critical control loops without software overhead.
Is the MCP33141D-10T-E/MS pin-compatible with the 14-bit MCP33151D-10T-E/MS?
Yes, the MCP33141D-10T-E/MS and MCP33151D-10T-E/MS share identical MSOP-10 pinouts, electrical interfaces, and timing specifications. They differ only in resolution (12-bit vs. 14-bit), dynamic performance (e.g., SNR = 73.8 dBFS vs. 83.8 dBFS), and INL/DNL-allowing drop-in upgrades where higher resolution is needed.
