Product details
Overview
MCP47CVD01T-E/MG from Microchip Technology is an 8-bit volatile-memory voltage-output DAC with I²C interface, 1 LSB INL, ±0.5 LSB zero-scale error, and operation from 2.7V to 5.5V. It delivers buffered analog output via VOUT pin and supports internal bandgap (1.214 V), VDD, or external VREF as reference source - used in sensor calibration and precision set-point trimming circuits.
For engineers reviewing the MCP47CVD01T-E/MG datasheet, MCP47CVD01T-E/MG pinout, MCP47CVD01T-E/MG application, or MCP47CVD01T-E/MG equivalent, key selection criteria include its 4 µs settling time, 270 kHz -3 dB bandwidth, 100 kΩ/1 kΩ programmable power-down pull-down resistors, and support for Standard/Fast/High-Speed I²C modes up to 3.4 Mbps.
Technical Context
This DAC uses a resistor ladder architecture with buffered op-amp output stage and supports three reference configurations: internal bandgap (1.214 V typical), device VDD, or external VREF (buffered/unbuffered). Gain options are 1× or 2×, with 2× enabled only when VREF ≠ VDD.
The I²C interface includes register-defined addressing using A0/A1 pins and supports Standard (100 kHz), Fast (400 kHz), and High-Speed (1.7 MHz / 3.4 MHz) modes. Power-on/brown-out reset ensures deterministic startup, and LAT/HVC pin enables MTP programming when driven to 7.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit (256 steps), no missing codes - defines minimum analog step size and quantization granularity. |
| INL | ±0.10 LSB - ensures monotonicity and linearity critical for closed-loop control accuracy. |
| Settling Time | 4 µs to ±0.5 LSB - enables fast update rates in dynamic calibration systems. |
| -3 dB Bandwidth | 270 kHz (VREF = 3.0 V, gain = 1) - supports audio-frequency and moderate-speed waveform generation. |
| Supply Voltage | 2.7 V to 5.5 V - compatible with industrial and automotive supply rails without level-shifting. |
| Reference Options | VDD, external VREF (1.0–VDD), or internal bandgap (1.214 V) - provides flexibility in system-level reference sourcing. |
| Power-Down Current | 0.5–2.4 µA - extends battery life in portable instrumentation during idle periods. |
Pinout & Package
Package: 10-lead MSOP (3 × 3 mm) with exposed pad (EP); RoHS-compliant, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply rail | Provides power to digital core and analog output stage; must be ≥2.7 V for full specification compliance. |
| VSS | Ground reference | Analog/digital common return; requires low-impedance connection to minimize noise coupling into DAC output. |
| VREF | Reference voltage input | Selectable reference source: internal bandgap, VDD, or external; unbuffered mode draws ≤176 µA. |
| VOUT | Analog output | Buffered voltage output capable of sourcing/sinking ±20 mA; settles within 4 µs to ±0.5 LSB. |
| SCL | I²C clock input | Accepts Standard (100 kHz), Fast (400 kHz), or High-Speed (3.4 MHz) clock; VIH = 0.7×VDD. |
| SDA | I²C data bidirectional | Open-drain interface supporting ACK/NACK; VOL ≤ 0.4 V at 3 mA load. |
| A0, A1 | I²C address select | Configure slave address bits; enable up to four devices on same bus without external hardware. |
| LAT/HVC | Latch or high-voltage command | Drives to 7.5 V for MTP programming; otherwise functions as latch enable for synchronous updates. |
Key Features
| Feature | Design Value |
|---|---|
| Volatile memory only | No nonvolatile storage - simplifies configuration management and avoids MTP wear-out concerns in frequently reprogrammed systems. |
| 1 LSB integral nonlinearity | Guaranteed ±0.10 LSB INL over temperature - eliminates need for per-unit calibration in mid-precision applications. |
| Programmable power-down | Selectable 100 kΩ or 1 kΩ VOUT pull-down - prevents floating outputs while minimizing current draw during sleep. |
| Three reference sources | Internal bandgap (1.214 V), VDD, or external VREF - allows optimal SNR trade-off depending on system reference architecture. |
| Extended temperature range | -40°C to +125°C operation - qualified for under-hood automotive and industrial motor-control environments. |
Applications
| Sensor Calibration | Set Point Trimming |
|---|---|

Use Value: Support for 3.4 Mbps High-Speed I²C enables rapid updates synchronized with host USB polling intervals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP47FVB01-E/MC | Same 8-bit volatile DAC family but in 8-pin SOIC package; lacks LAT/HVC pin and MTP capability - not applicable here since MCP47CVD01 has MSOP-10 and LAT/HVC functionality. | SOIC footprint incompatible with MSOP-10 PCB layout; no high-voltage programming path. | Select only if board space permits SOIC and MTP programming is unnecessary. |
| AD5620BRMZ-1 | 8-bit SPI-interface DAC with internal 2.5 V reference; no I²C support, no programmable pull-down, higher 300 µA supply current. | Requires SPI host interface and level-shifting for 2.5 V reference; unsuitable for I²C-only systems. | Choose only when SPI is preferred and higher power budget is acceptable. |
Compared with MCP47FVB01-E/MC and AD5620BRMZ-1, the MCP47CVD01T-E/MG uniquely combines I²C compatibility, MSOP-10 compactness, LAT/HVC-controlled latching, and ultra-low power-down current - making it optimal for space-constrained, I²C-based embedded calibration nodes.

FAQ
What is the maximum I²C clock frequency supported by the MCP47CVD01T-E/MG?
The MCP47CVD01T-E/MG supports Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) I²C modes. At 3.4 MHz, typical supply current rises to 550 µA (single-channel) - verify timing margins and bus capacitance in your layout before deploying at maximum speed. The MCP47CVD01T-E/MG does not require external pull-ups beyond standard I²C specifications.
Does the MCP47CVD01T-E/MG include nonvolatile memory?
No, the MCP47CVD01T-E/MG uses volatile RAM only - all DAC register contents are lost on power removal. This distinguishes it from MCP47CMDxx variants with MTP memory. The MCP47CVD01T-E/MG requires host MCU initialization at startup to restore desired output values.
What reference voltage options are available for the MCP47CVD01T-E/MG?
The MCP47CVD01T-E/MG supports three reference sources: internal bandgap (1.214 V typical), device VDD, or external voltage applied to the VREF pin. When using external VREF in unbuffered mode, input impedance is ~73.5 kΩ and max current draw is 176 µA. The MCP47CVD01T-E/MG does not support external reference buffering unless configured via control register.
Can the MCP47CVD01T-E/MG operate from a 1.8 V supply?
The MCP47CVD01T-E/MG supports 1.8 V to 2.7 V operation for digital interface only - analog performance (INL, gain error, settling time) is degraded outside the 2.7 V–5.5 V full-spec range. At 1.8 V, VREF must be ≤1.8 V and internal bandgap is unavailable. The MCP47CVD01T-E/MG remains functional but requires validation for target accuracy requirements.
What is the function of the LAT/HVC pin on the MCP47CVD01T-E/MG?
The LAT/HVC pin serves dual roles: as a latch enable for synchronous DAC updates (LAT mode), or as a high-voltage input (7.5 V) to initiate MTP programming - though MTP is unused in the volatile MCP47CVD01T-E/MG. In normal operation, driving LAT/HVC high pulses the DAC output latch; leaving it low enables auto-update on write completion. The MCP47CVD01T-E/MG uses this pin exclusively for latching, not memory writes.
