Product details
Overview
MCP33141-10T-E/MN from Microchip Technology is a 12-bit, 1 Msps single-ended SAR analog-to-digital converter with no missing codes, ultra-low standby current (1.5 µA), and integrated self-calibration for offset, gain, and linearity errors. It operates from a 1.8V analog supply (AVDD), supports digital I/O voltages from 1.7V to 5.5V (DVIO), and accepts an external reference up to 5.1V - enabling high-precision voltage measurement in battery-powered motor control and EV battery management systems.
For engineers reviewing the MCP33141-10T-E/MN datasheet, MCP33141-10T-E/MN pinout, MCP33141-10T-E/MN application, or MCP33141-10T-E/MN equivalent, this device delivers deterministic 1 µs conversion cycle time, SPI-compatible 3-wire interface with optional BUSY indicator, built-in data accumulator (up to 1024 samples), and AEC-Q100 Grade 1 qualification (-40°C to +125°C) for automotive and industrial embedded sensing.
Technical Context
The MCP33141-10T-E/MN uses a successive approximation register (SAR) architecture with internal clock generation, decoupling conversion timing from SPI clock (SCLK) rate - allowing SCLK up to 100 MHz while maintaining 1 Msps throughput. Its pseudodifferential input supports single-ended operation with full-scale range of 0V to VREF (up to 5.1V), independent of AVDD.
It features automatic power-up calibration (~500–650 ms) and on-demand recalibration via SPI command, ensuring stable INL (±0.09 LSB) and DNL (±0.05 LSB) across temperature. The device enters low-current Standby mode (~1.5 µA) between conversions, with input acquisition time of 490 ns (typ.) and conversion time of 510 ns (typ.).

Pinout & Package
TDFN-10 package (3 mm × 3 mm, 0.5 mm pitch) with exposed thermal pad (EP) for enhanced thermal dissipation in high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN+ | Analog input (single-ended) | Primary analog signal input; referenced to GND; full-scale range 0V to VREF. |
| GND | Analog/digital ground | Common reference for AVDD, DVIO, VREF, and analog input - requires low-impedance connection to minimize noise. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7142IRUGT | 12-bit, 1 Msps, but uses internal reference (2.5V fixed); no external VREF support; lower SNR (70.5 dBFS). | Best suited for space-constrained, single-supply systems where reference flexibility is not required. | Select when board area is critical and VREF = 2.5V suffices; avoid if programmable full-scale range (0–5.1V) is needed. |
| MCP33141-05T-E/MN | Same 12-bit resolution and pinout, but 500 ksps sample rate; lower conversion current (0.33 mA) and reduced dynamic power. | Optimized for lower-bandwidth applications like temperature or pressure sensing where 1 Msps is unnecessary. | Choose for battery-powered devices prioritizing average power over speed; retains identical calibration, interface, and qualification. |
Compared with ADS7142IRUGT, the MCP33141-10T-E/MN provides wider input range via external VREF and higher SNR; compared with MCP33141-05T-E/MN, it doubles throughput at the cost of +0.33 mA active current - making it optimal for real-time control where latency matters.

FAQ
What is the maximum external reference voltage supported by the MCP33141-10T-E/MN?
The MCP33141-10T-E/MN supports an external reference voltage (VREF) up to 5.1V, independent of the 1.8V AVDD supply. This allows full-scale input ranges from 0V to 5.1V, enabling direct measurement of standard industrial signals without external amplification or attenuation. Operation at VREF = 5.1V achieves optimal SNR (73.3 dBFS) and SFDR (101.4 dBc) at 10 kHz input frequency.
Does the MCP33141-10T-E/MN require external level-shifting when interfacing with a 5V microcontroller?
No, the MCP33141-10T-E/MN does not require external level-shifting when interfacing with a 5V microcontroller. Its DVIO pin accepts digital I/O voltages from 1.7V to 5.5V, and all digital inputs (CNVST, SCLK, SDI) are Schmitt-triggered with hysteresis. The SDO output is 5V-tolerant and drives valid logic levels across the full DVIO range - simplifying design with mixed-voltage hosts like PIC32MZ or STM32H7.
How does the built-in data accumulator improve measurement resolution in the MCP33141-10T-E/MN?
The built-in data accumulator in the MCP33141-10T-E/MN integrates up to 1024 consecutive 12-bit conversion results and outputs the averaged value - increasing effective number of bits (ENOB) up to 18 bits. This reduces quantization noise without firmware overhead or external DSP, enabling high-resolution DC measurements (e.g., battery voltage drift) while retaining the device's 1 Msps native speed for transient capture.
What is the typical power consumption of the MCP33141-10T-E/MN during conversion and standby modes?
The MCP33141-10T-E/MN consumes ~0.66 mA (660 µA) during active conversion at 1 Msps and only ~1.5 µA in Standby mode - where sampling capacitors remain connected to the input for fast wake-up. Total power dissipation is ~3.6 mW at 1 Msps (including AVDD, DVIO, and VREF currents), dropping to ~3.3 µW in Standby. This ultra-low quiescent current makes it ideal for always-on battery monitoring nodes.
Is the MCP33141-10T-E/MN pin-compatible with other devices in the MCP331xx family?
Yes, the MCP33141-10T-E/MN is pin-compatible with MCP33151-10T-E/MN, MCP33141-05T-E/MN, and MCP33151-05T-E/MN in the same TDFN-10 package. All share identical pinout, interface protocol, and supply requirements - allowing hardware reuse across 12-/14-bit and 500 ksps/1 Msps variants. Firmware changes are limited to timing and resolution handling.
