Product details
Overview
MCP47CVD01T-E/UN from Microchip Technology is an 8-bit volatile-memory voltage-output Digital-to-Analog Converter (DAC) with I²C interface, ±0.1 LSb integral nonlinearity (INL), 2.7V–5.5V supply range, and buffered single-channel VOUT. It supports internal bandgap (1.214 V), external VREF, or VDD as reference source and operates across –40°C to +125°C for sensor calibration and precision set-point trimming.
For engineers reviewing the MCP47CVD01T-E/UN datasheet, MCP47CVD01T-E/UN pinout, MCP47CVD01T-E/UN application, or MCP47CVD01T-E/UN equivalent, key selection criteria include its 4 µs settling time, 100 kΩ/1 kΩ programmable power-down pull-down resistors, I²C high-speed mode support (up to 3.4 Mbps), 1.214 V internal reference accuracy, and MSOP-10 package compatibility with space-constrained industrial control designs.
Technical Context
The MCP47CVD01T-E/UN implements a resistor ladder architecture with buffered op-amp output, enabling rail-to-rail voltage generation referenced to VDD, external VREF, or internal 1.214 V bandgap. Its I²C interface supports Standard (100 kHz), Fast (400 kHz), and High-Speed (3.4 MHz) modes with two address-select pins (A0/A1) for multi-device bus configuration.
Power management includes POR/BOR circuitry ensuring reliable reset at VDD > 1.75 V (rising) and < 1.61 V (falling), plus three configurable power-down states that disconnect the output buffer and select either 100 kΩ or 1 kΩ pull-down resistors - critical for low-power portable instrumentation and battery-operated systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit (256 steps); enables 0.39% full-scale step resolution for fine-grained analog control in closed-loop systems. |
| INL | ±0.1 LSb max; ensures monotonicity and < 0.04% FSR absolute linearity error over temperature, critical for calibration accuracy. |
| Settling Time | 4 µs to ±0.5 LSb; supports dynamic waveform generation and fast DAC updates in real-time feedback loops. |
| Reference Options | VDD, external VREF (buffered/unbuffered), or internal 1.214 V bandgap; allows flexible system-level reference sourcing without external components. |
| Supply Range | 2.7 V to 5.5 V; compatible with both 3.3 V and 5 V logic domains and retains functionality down to 1.8 V (reduced specs). |
| Operating Temp | –40°C to +125°C; qualified for under-hood automotive sensors, industrial PLC modules, and harsh-environment data acquisition. |
| I²C Speed | Up to 3.4 Mbps (High-Speed mode); reduces command latency in multi-DAC configurations and high-throughput control systems. |
Pinout & Package
Package: 10-lead MSOP (3 mm × 3 mm, 0.5 mm pitch), thermally enhanced with exposed pad (EP) for improved thermal dissipation in continuous-output applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply input | Provides power for digital core, reference circuitry, and output amplifier; must be decoupled locally to suppress noise coupling into analog output. |
| VSS | Ground reference | Analog/digital common return; requires low-impedance connection to minimize ground bounce affecting INL and offset performance. |
| VOUT | Analog voltage output | Buffered, rail-to-rail capable output driving up to ±20 mA; supports direct connection to op-amp inputs or actuator control lines. |
| VREF | External reference input | Accepts 1.0 V–VDD reference voltage; when used with gain=2, VREF must be ≤ VDD/2 to avoid clipping and maintain accuracy. |
| SCL | I²C clock input | Open-drain input with Schmitt trigger; supports standard/fast/high-speed I²C timing; requires external pull-up to VDD. |
| SDA | I²C data bidirectional | Open-drain bidirectional line with Schmitt trigger; shares bus with other I²C peripherals; pull-up required. |
| A0 / A1 | Address select inputs | Two binary pins setting 4 possible I²C slave addresses (0x48–0x4B); enable up to four MCP47CVD01T-E/UN devices on one bus. |
| LAT/HVC | Latch or high-voltage programming | In DAC mode: latches new code to output; in MTP mode: accepts 7.5 V for volatile register write - not used in MCP47CVD01T-E/UN (volatile-only). |
Key Features
| Feature | Design Value |
|---|---|
| 1 LSb INL specification | Guarantees monotonic operation and < 0.04% FSR linearity error across –40°C to +125°C, eliminating code-dependent gain errors in precision calibration. |
| Three power-down modes | Configurable high-Z output with 100 kΩ or 1 kΩ pull-down resistors - reduces system standby current to 0.5–2.4 µA while preserving state integrity. |
| Internal 1.214 V bandgap reference | Stable, factory-trimmed reference with ±18 ppm/°C tempco; eliminates need for external precision reference in cost-sensitive sensor offset trimming. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP47FVB01-E/MS | Same 8-bit volatile DAC family but in 10-lead DFN (3×3 mm); identical electrical specs and pinout-compatible with MSOP-10 footprint. | No thermal pad; slightly lower thermal resistance; same industrial temperature rating and I²C timing. | Select for board-level footprint flexibility where DFN reflow profile is preferred over MSOP. |
| AD5620BRJZ-REEL7 | 8-bit SPI-interface DAC (not I²C); 10-lead SOT-23; ±1 LSB INL; 2.7–5.5 V supply; 10 µs settling time. | Requires SPI host interface and separate level-shifting for mixed-voltage systems; lacks internal bandgap reference. | Choose only if existing design uses SPI infrastructure and external reference is already available. |
Compared with MCP47FVB01-E/MS, the MCP47CVD01T-E/UN offers identical performance in an MSOP package with exposed pad for superior thermal management; versus AD5620BRJZ-REEL7, it provides native I²C support, faster settling, and integrated reference - reducing BOM count and layout complexity.

FAQ
What is the maximum I²C clock frequency supported by the MCP47CVD01T-E/UN?
The MCP47CVD01T-E/UN supports I²C High-Speed mode up to 3.4 Mbps, in addition to Standard (100 kHz) and Fast (400 kHz) modes. This enables rapid register writes and synchronized multi-DAC updates. The device meets I²C specification timing requirements across its full operating temperature range (–40°C to +125°C) and supply range (2.7 V to 5.5 V). No external speed-limiting components are required.
Does the MCP47CVD01T-E/UN include an internal voltage reference?
Yes, the MCP47CVD01T-E/UN integrates a factory-trimmed 1.214 V bandgap reference with ±18 ppm/°C temperature coefficient and 52 µV/mA load regulation. This reference can be selected as the DAC's voltage source via configuration bits, eliminating the need for external precision references in applications such as sensor offset trimming and portable instrumentation.
What are the power-down options available on the MCP47CVD01T-E/UN?
The MCP47CVD01T-E/UN offers three power-down configurations: high-impedance output with 100 kΩ pull-down, high-impedance output with 1 kΩ pull-down, or full output disconnect (no pull-down). These are controlled via dedicated PD bits and reduce quiescent current to 0.5–2.4 µA. This capability is essential for battery-powered devices requiring ultra-low standby power without sacrificing wake-up speed.
Is the MCP47CVD01T-E/UN pin-compatible with other devices in the MCP47CXDX family?
Yes - the MCP47CVD01T-E/UN shares identical pinout and package (10-lead MSOP) with all single-channel MCP47CXDX1 variants, including MCP47CVD11T-E/UN (10-bit) and MCP47CVD21T-E/UN (12-bit). This enables resolution scalability without PCB redesign, provided firmware accommodates differing code widths and INL specifications.
What is the guaranteed integral nonlinearity (INL) specification for the MCP47CVD01T-E/UN?
The MCP47CVD01T-E/UN guarantees ±0.1 LSb integral nonlinearity over its full operating range (–40°C to +125°C, 2.7 V to 5.5 V). This corresponds to < 0.04% of full-scale range and ensures monotonic behavior with no missing codes - a critical requirement for closed-loop control systems and precision calibration applications where code-to-voltage mapping must remain predictable and repeatable.
