Product details
Overview
MCP33151D-10-E/MN from Microchip Technology is a 14-bit, 1 Msps fully differential successive approximation register (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 with 1.8V AVDD, supports 1.7–5.5V DVIO, and accepts external VREF up to 5.1V, enabling ±5.1V differential input range - ideal for high-precision battery management and motor control systems.
For engineers reviewing the MCP33151D-10-E/MN datasheet, MCP33151D-10-E/MN pinout, MCP33151D-10-E/MN application, or MCP33151D-10-E/MN equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (-40°C to +125°C), 83.8 dBFS SNR at 10 kHz, 100 MHz SPI clock support, built-in data accumulator for ENOB up to 18.5 bits, and dual-package availability in TDFN-10 and MSOP-10.
Technical Context
The MCP33151D-10-E/MN employs a SAR architecture with internal clock generation, decoupling conversion timing from SPI SCLK. Its differential input stage supports full-scale ranges from –VREF to +VREF, with common-mode voltage range of 0 to VREF/2 and –3 dB bandwidth of 45 MHz.
Self-calibration occurs automatically at power-up (~400–550 ms) and on-demand via SPI command; it corrects offset, gain, and integral nonlinearity (INL ±0.27 LSB typical). The device enters low-power standby between conversions, consuming only ~1.5 µA while maintaining input acquisition readiness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit with no missing codes - guarantees monotonicity and deterministic code transitions across full scale. |
| Sample Rate | 1 Msps throughput - enables real-time capture of signals up to ~450 kHz (Nyquist-limited by 45 MHz input bandwidth). |
| Differential Input Range | ±5.1V full-scale - supports high-voltage sensor interfaces without external signal conditioning. |
| SNR / SINAD | 83.8 dBFS / 83.8 dBFS at fIN = 10 kHz, VREF = 5V - delivers >13.9 effective bits in typical operation. |
| INL / DNL | ±0.27 LSB / ±0.11 LSB typical - ensures high accuracy in closed-loop control and precision measurement. |
| Supply Voltages | AVDD = 1.8V, DVIO = 1.7–5.5V, VREF = AVDD to 5.1V - allows direct interfacing with 1.8V/3.3V/5V host MCUs without level shifters. |

FAQ
What is the maximum SPI clock frequency supported by the MCP33151D-10-E/MN?
The MCP33151D-10-E/MN supports an SPI SCLK frequency up to 100 MHz under DVIO ≥3.3V conditions. At lower DVIO (e.g., 1.7V), the maximum SCLK is reduced to 62.5 MHz. This high-speed interface enables rapid data transfer without bottlenecking the 1 Msps conversion rate of the MCP33151D-10-E/MN.
Does the MCP33151D-10-E/MN require an external reference voltage?
Yes, the MCP33151D-10-E/MN requires an external reference voltage applied to the VREF pin, which can range from AVDD up to 5.1V. This reference defines the differential full-scale input range (±VREF), and a 10 µF tantalum decoupling capacitor is recommended at the VREF pin to ensure stability and noise immunity for the MCP33151D-10-E/MN.
How does the self-calibration feature of the MCP33151D-10-E/MN work?
The MCP33151D-10-E/MN performs automatic self-calibration at power-up (~400–550 ms) to correct offset, gain, and linearity errors. Users can also trigger recalibration on-demand via SPI command. This ensures sustained accuracy across temperature and aging - critical for long-term deployments where the MCP33151D-10-E/MN operates in harsh environments like automotive battery packs.
What package options are available for the MCP33151D-10-E/MN?
The MCP33151D-10-E/MN is offered in two RoHS-compliant packages: the 3 mm × 3 mm TDFN-10 with exposed thermal pad (lower θJA = 68°C/W) and the MSOP-10 (θJA = 202°C/W). Both support automotive reflow profiles and share identical pinout and functionality - allowing layout flexibility based on thermal and board-space constraints for the MCP33151D-10-E/MN.
Is the MCP33151D-10-E/MN suitable for battery-powered applications?
Yes, the MCP33151D-10-E/MN is optimized for battery-powered applications: it draws only ~1.5 µA in standby mode and ~0.66 mA during conversion at 1 Msps. Its wide DVIO range (1.7–5.5V) supports direct connection to single-cell Li-ion or multi-cell alkaline supplies, making it ideal for portable test gear and remote sensors using the MCP33151D-10-E/MN.
