Product details
Overview
MCP47CVB12-E/UN from Microchip Technology is a dual-channel, 12-bit volatile-memory voltage-output DAC with I²C interface, ±1 LSb integral nonlinearity, 16 µs settling time, and operation from 2.7V to 5.5V. It supports internal bandgap (1.214 V), external VREF, or VDD as reference source and delivers buffered analog outputs for precision calibration in embedded sensor systems.
For engineers reviewing the MCP47CVB12-E/UN datasheet, MCP47CVB12-E/UN pinout, MCP47CVB12-E/UN application, or MCP47CVB12-E/UN equivalent, key selection criteria include dual 12-bit resolution, I²C high-speed mode (3.4 Mbps), extended temperature range (–40°C to +125°C), programmable power-down modes, and QFN-16 package compatibility with space-constrained industrial control designs.
Technical Context
The MCP47CVB12-E/UN implements a resistor ladder architecture with two independent 4096-step DAC cores, each driving a rail-to-rail output amplifier. Its I²C interface supports Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes with register-defined slave addressing via A0/A1 pins.
Reference selection is configurable per channel: internal bandgap (1.214 V ±16 ppm/°C), buffered/unbuffered external VREF (1.0 V to VDD), or direct VDD sourcing. Gain options are 1× (all references) or 2× (external VREF only, limited to VDD/2 max).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit (4096 steps), no missing codes - enables 0.024% full-scale step resolution for fine-grained analog control. |
| INL | ±1 LSb max - ensures monotonicity and <0.025% full-scale linearity error across temperature. |
| Settling Time | 16 µs to ±1/2 LSb - supports update rates up to ~60 kSPS for dynamic waveform generation. |
| Supply Range | 2.7V to 5.5V - compatible with single-supply industrial microcontrollers and battery-powered instrumentation. |
| I²C Speed | Up to 3.4 Mbps - enables rapid configuration and real-time DAC updates without bus contention. |
| Temp Range | –40°C to +125°C - qualified for under-hood automotive, motor drive feedback, and industrial PLC environments. |
| Output Drive | ±20 mA - directly interfaces with op-amp inputs, LED drivers, or low-impedance transducer bias networks. |
Pinout & Package
Package: 16-lead 3 × 3 mm QFN with exposed pad (EP). Pin-compatible with other MCP47CXBXX dual-channel variants in same footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply | 2.7–5.5 V analog/digital supply; powers DAC core, I²C logic, and output amplifiers. |
| VSS | Ground | Common reference for analog and digital sections; connects to EP for thermal performance. |
| VOUT0 / VOUT1 | Analog outputs | Buffered, rail-to-rail voltage outputs for independent DAC channels; each capable of ±20 mA sink/source. |
| VREF | Reference input | Accepts external reference (1.0–VDD V); when used with gain=2, must be ≤VDD/2 to avoid clipping. |
| SCL / SDA | I²C interface | Two-wire serial bus supporting Standard/Fast/High-Speed modes; 10 pF pin capacitance minimizes signal integrity issues. |
| A0 / A1 | Address select | Hardware-configurable slave address bits; enable up to four devices on same I²C bus without software arbitration. |
| LAT/HVC | Latency control / HV programming | In dual QFN package, serves as LAT0/LAT1 latch trigger; at VIHH (7.5 V), enables MTP write cycles (not used in volatile MCP47CVB12). |
| NC | No connect | Unused pins (pins 11–16 except EP); must remain unconnected per datasheet layout guidance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual 12-bit DAC channels | Independent, simultaneously updated outputs eliminate inter-channel timing skew in closed-loop control. |
| Volatile memory only | No MTP programming overhead; immediate power-on default (7FFh) simplifies boot-time initialization. |
| Three reference options | Internal bandgap (1.214 V), external VREF, or VDD - enables flexible system-level voltage scaling without external components. |
| Programmable power-down | Selectable 100 kΩ or 1 kΩ pull-down on VOUT during sleep - prevents floating nodes while minimizing leakage current (0.65 µA typical). |
| Extended temperature grade | –40°C to +125°C operation with <3 ppm/°C VOUT tempco - maintains accuracy in thermally aggressive enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP47CMB12-E/UN | Nonvolatile MTP memory (32 writes), identical 12-bit dual DAC specs, same QFN-16 package. | Required where power-on default output must persist across resets without host MCU intervention. | Select MCP47CMB12-E/UN if persistent calibration values or factory-set configurations are mandatory. |
| AD5662BRMZ-REEL7 | Single 16-bit DAC, SPI interface, 2.7–5.5 V supply, ±4 LSB INL, 10 µs settling, MSOP-10 package. | Higher resolution but single-channel and SPI-only; lacks dual output synchronization and I²C flexibility. | Choose AD5662BRMZ-REEL7 only when 16-bit precision outweighs need for dual outputs and I²C bus compatibility. |
Compared with MCP47CMB12-E/UN, the MCP47CVB12-E/UN eliminates MTP write complexity and reduces boot latency; versus AD5662BRMZ-REEL7, it trades resolution for dual-channel concurrency and I²C integration-critical for multi-sensor systems with constrained MCU GPIO.

FAQ
What is the maximum I²C clock frequency supported by the MCP47CVB12-E/UN?
The MCP47CVB12-E/UN supports High-Speed I²C mode up to 3.4 Mbps, in addition to Standard (100 kHz) and Fast (400 kHz) modes. This enables rapid register writes and real-time DAC updates in time-critical applications such as closed-loop motor control. The device meets I²C specification timing requirements across its full operating temperature range (–40°C to +125°C), and the SCL/SDA pins exhibit 10 pF capacitance to maintain signal integrity at high speeds.
Does the MCP47CVB12-E/UN include nonvolatile memory?
No, the MCP47CVB12-E/UN uses volatile memory only. It retains DAC output values only while powered; upon power-up or reset, it defaults to 7FFh (mid-scale for 12-bit). Unlike the MCP47CMB12-E/UN variant, it does not incorporate MTP memory for storing configuration or output values across power cycles. This simplifies initialization and avoids high-voltage programming requirements on the LAT/HVC pin.
What reference voltage options are available for the MCP47CVB12-E/UN?
The MCP47CVB12-E/UN supports three reference sources: the internal 1.214 V bandgap (±16 ppm/°C), an external voltage applied to the VREF pin (1.0 V to VDD), or the VDD supply itself. When using external VREF, gain options of 1× or 2× are selectable; the 2× gain requires VREF ≤ VDD/2 to prevent output saturation. All reference selections are configured via control registers and do not require external components.
What is the settling time specification for the MCP47CVB12-E/UN, and under what conditions is it measured?
The MCP47CVB12-E/UN has a guaranteed settling time of 16 µs to within ±1/2 LSb of final value, measured when the DAC code transitions between 1/4 and 3/4 of full-scale (e.g., 400h → C00h in 12-bit mode), with RL = 2 kΩ and CL = 100 pF. This specification holds across the full –40°C to +125°C temperature range and 2.7–5.5 V supply, enabling reliable timing margins in high-update-rate applications like waveform synthesis or adaptive biasing.
Can the MCP47CVB12-E/UN operate from a 1.8 V supply?
The MCP47CVB12-E/UN is specified for full performance from 2.7 V to 5.5 V. At 1.8 V to 2.7 V, analog specifications (INL, settling time, output drive) are degraded and not guaranteed - only the I²C interface remains functional. For reliable 12-bit accuracy and ±1 LSb linearity, operation below 2.7 V is not recommended. The POR threshold is 1.75 V, ensuring reset release above this level, but analog functionality requires ≥2.7 V.
