Product details
Overview
MCP48CVB11-E/MF from Microchip Technology is a single-channel, 10-bit volatile-memory DAC with buffered voltage output, SPI interface, and ±0.25 LSb integral nonlinearity (INL) over –40°C to +125°C. It supports 2.7V–5.5V supply, selectable reference sources (VDD, external VREF, or internal 1.214V bandgap), and 1x/2x output gain-enabling precision analog setpoint generation in sensor calibration and industrial control loops.
For engineers reviewing the MCP48CVB11-E/MF datasheet, MCP48CVB11-E/MF pinout, MCP48CVB11-E/MF application, or MCP48CVB11-E/MF equivalent, key selection considerations include its 10-bit resolution with guaranteed monotonicity, 16 µs settling time, SPI write speed up to 50 MHz, and support for high-impedance power-down modes with configurable pull-down resistors (100 kΩ or 1 kΩ).
Technical Context
The MCP48CVB11-E/MF implements a resistor ladder architecture with buffered op-amp output, supporting four-wire SPI in '00' and '11' modes. Its reference selection logic (VRxB:VRxA = '10', '01', or '11') directly determines whether VDD, external VREF, or internal bandgap serves as the DAC reference-and enables 1x or 2x gain only when external VREF is used.
Power-on/brown-out reset ensures deterministic startup with 130 µs delay to output-driven state. The LAT/HVC pin provides access to WiperLock™ technology for volatile register latching and MTP programming (requiring 7.5V high-voltage pulse), though this functionality is disabled in the volatile-memory variant MCP48CVB11-E/MF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit (1024 steps); guarantees monotonic output and no missing codes across full temperature range. |
| Integral Nonlinearity (INL) | ±0.25 LSb max; ensures accurate absolute voltage output without calibration in closed-loop trimming applications. |

Pinout & Package
Package: 10-lead MSOP or 10-lead 3×3 DFN (MCP48CVB11-E/MF uses MSOP-10 per Microchip ordering code suffix "/MF"). Exposed pad optional; not electrically connected.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply rail | Provides power to digital core and analog output stage; also selectable as DAC reference source. |
| VSS | Ground reference | Analog and digital common return; must be low-impedance for stable DAC output and SPI signaling. |
| VREF | External reference input | Accepts buffered or unbuffered external voltage (1.000V–VDD); enables precise scaling independent of VDD. |

| SDO | SPI data output | Read-back capability for status registers and DAC value; open-drain compatible with 25 mA drive strength. |
| LAT/HVC | Latch or high-voltage control | In volatile mode: latches current DAC value to output; no MTP programming enabled on MCP48CVB11-E/MF. |
| NC | No connect | Pin 10 in MSOP-10 package is unconnected; must be left floating or tied to VSS per layout guidelines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP48FVB11-E/MF | Same 10-bit resolution and MSOP-10 package, but features faster 100 MHz SPI interface and improved THD (–82 dB vs. –76 dB). | Preferred for high-speed waveform generation or noise-sensitive audio applications where spectral purity is critical. | Select MCP48FVB11-E/MF when >50 MHz update rate or lower harmonic distortion is required; otherwise MCP48CVB11-E/MF offers cost-effective baseline performance. |
| DAC8560IDGSR | 16-bit resolution, I²C interface, internal 2.5V reference, and 10 µs settling-but requires external level-shifting for 1.8V logic compatibility. | Better suited for high-precision metrology or medical instrumentation requiring >12-bit accuracy and low-noise design. | Choose DAC8560IDGSR only if 16-bit resolution and I²C integration outweigh SPI compatibility and smaller footprint needs of MCP48CVB11-E/MF. |
Compared with MCP48FVB11-E/MF and DAC8560IDGSR, the MCP48CVB11-E/MF delivers optimal balance of 10-bit precision, SPI simplicity, wide temperature range, and compact MSOP-10 packaging-making it ideal for cost-sensitive industrial and sensor-trimming applications where 50 MHz throughput and ±0.25 LSb linearity are sufficient.

FAQ
What is the maximum SPI clock frequency supported by the MCP48CVB11-E/MF?
The MCP48CVB11-E/MF supports up to 50 MHz for write operations and 25 MHz for read operations in SPI Mode '11'. This allows sustained update rates exceeding 20 kSPS in microcontroller-based systems. The device maintains full timing compliance across its –40°C to +125°C operating range and 2.7V–5.5V supply voltage, with no derating required for speed or temperature.
Does the MCP48CVB11-E/MF include nonvolatile memory for retaining DAC settings after power loss?
No, the MCP48CVB11-E/MF uses volatile RAM-only memory. It does not retain DAC output values or configuration registers after power removal. For nonvolatile storage, Microchip offers the pin-compatible MCP48CMB11-E/MF variant with 32-location MTP memory. The 'V' in MCP48CVB11-E/MF explicitly denotes volatile memory architecture.
Can the MCP48CVB11-E/MF operate from a 1.8V supply?
The MCP48CVB11-E/MF supports 1.8V to 2.7V operation, but only with reduced analog specifications-including degraded INL, offset, and gain error performance. Full DC and AC specifications-including ±0.25 LSb INL and 16 µs settling-are guaranteed only from 2.7V to 5.5V. SPI interface remains functional at 1.8V, enabling digital communication in ultra-low-power sleep modes.
What reference voltage options are available for the MCP48CVB11-E/MF?
The MCP48CVB11-E/MF supports three reference sources: the device's VDD supply, an external voltage applied to the VREF pin (buffered or unbuffered), or the internal 1.214V bandgap. When using external VREF, gain options of 1x or 2x are available; 2x gain requires VREF ≤ VDD/2. Internal bandgap operation provides temperature-stable output with ±16 ppm/°C drift.
How is the output impedance managed during power-down mode on the MCP48CVB11-E/MF?
In power-down mode, the MCP48CVB11-E/MF disconnects the output buffer and configures VOUT as high-impedance. Users may select either a 100 kΩ or 1 kΩ internal pull-down resistor to ground via control bits PD1:PD0. This prevents floating outputs in standby states while minimizing leakage current-critical for battery-powered sensor nodes and isolated analog subsystems.
