Microchip Technology MCP47CVB11-E/MF

Overview

MCP47CVB11-E/MF from Microchip Technology is a single-channel, 10-bit volatile-memory DAC with buffered voltage output, I²C interface, ±0.25 LSb integral nonlinearity (INL), and operation from 2.7V to 5.5V. It supports internal band gap (1.214 V), VDD, or external VREF as reference source and delivers 1x or 2x output gain-used in precision sensor calibration and set-point trimming circuits.

For engineers reviewing the MCP47CVB11-E/MF datasheet, MCP47CVB11-E/MF pinout, MCP47CVB11-E/MF application, or MCP47CVB11-E/MF equivalent, key selection criteria include its 10-bit resolution, 16 µs settling time, 1 LSb INL specification, dual power-down resistor options (1 kΩ/100 kΩ), and support for High-Speed I²C up to 3.4 Mbps.

Technical Context

The MCP47CVB11-E/MF implements a resistor ladder architecture with buffered op-amp output stage, enabling rail-to-rail voltage output with 60 kHz –3 dB bandwidth and 0.15 V/µs slew rate. Its I²C interface supports Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes using two address-select pins (A0/A1) for slave addressing.

Power management includes POR/BOR reset protection, three selectable power-down modes (high-Z output + 1 kΩ or 100 kΩ pull-down), and ultra-low 0.65 µA typical current in PD mode. Reference selection is controlled via VRxB:VRxA bits, allowing flexible sourcing from VDD, external VREF (buffered/unbuffered), or internal 1.214 V band gap.

FAQ

What is the maximum I²C clock frequency supported by the MCP47CVB11-E/MF?

The MCP47CVB11-E/MF supports High-Speed I²C mode up to 3.4 Mbps, in addition to Standard (100 kHz) and Fast (400 kHz) modes. This capability enables rapid DAC register updates in time-critical applications such as closed-loop control or dynamic calibration sequences. The device meets I²C bus timing requirements across its full operating temperature range (–40°C to +125°C), and the SCL/SDA pins feature Schmitt-trigger inputs for noise immunity. The MCP47CVB11-E/MF does not require external level shifters for 3.3 V or 5 V I²C buses.

Does the MCP47CVB11-E/MF include an internal voltage reference?

Yes, the MCP47CVB11-E/MF integrates a precision internal band gap reference of 1.214 V (typical), with ±16 ppm/°C temperature coefficient and 30 µV/mA load regulation. This reference can be selected as the DAC's voltage source via configuration bits, eliminating the need for external reference ICs in many calibration and trimming applications. When enabled, it provides stable, factory-trimmed performance across the full –40°C to +125°C range - a key advantage of the MCP47CVB11-E/MF over reference-less DACs.

What are the power-down options available on the MCP47CVB11-E/MF?

The MCP47CVB11-E/MF offers three configurable power-down states: high-impedance output only, or high-Z plus 1 kΩ or 100 kΩ pull-down to VSS. These modes reduce supply current to just 0.65 µA (typical), making the MCP47CVB11-E/MF suitable for battery-powered systems. Power-down is controlled via dedicated PD bits in the configuration register and takes effect within 1.5 µs (TPDE). The output remains stable during transitions, and the DAC retains its last code value in volatile memory - a core behavior of the MCP47CVB11-E/MF.

Can the MCP47CVB11-E/MF operate from a 1.8 V supply?

No, the MCP47CVB11-E/MF requires a minimum supply voltage of 2.7 V for full analog and digital specifications. While the I²C interface may function at 1.8 V (per VIH/VIL thresholds), analog performance-including INL, gain error, and reference accuracy-is only guaranteed from 2.7 V to 5.5 V. Operation below 2.7 V results in reduced specifications and is not recommended for precision applications. The MCP47CVB11-E/MF POR threshold is 1.75 V (max), ensuring reliable reset at nominal 2.7 V startup.

Is the MCP47CVB11-E/MF pin-compatible with other devices in the MCP47CXBXX family?

Yes, the MCP47CVB11-E/MF shares identical pinout and footprint with all 10-lead variants in the MCP47CXBXX family, including MCP47CVB01-E/MF (8-bit), MCP47CVB21-E/MF (12-bit), and nonvolatile MCP47CMBxx-E/MF versions. This allows direct substitution within the same package type (MSOP or DFN) without PCB redesign. However, register maps and memory behavior differ - volatile vs. MTP - so firmware must be validated for the target device. The MCP47CVB11-E/MF maintains consistent timing, electrical, and thermal characteristics across this pin-compatible group.
