Product details
Overview
MCP48CMB01-E/MG from Microchip Technology is a single-channel, 8-bit nonvolatile-memory digital-to-analog converter (DAC) with buffered voltage output, SPI interface, and ±0.10 LSb integral nonlinearity. It operates from 2.7V to 5.5V, supports internal band gap (1.214V), external VREF, or VDD as reference, and delivers 16 µs settling time. It is used in sensor calibration circuits where power-up repeatability and factory-set offset trimming are required.
For engineers reviewing the MCP48CMB01-E/MG datasheet, MCP48CMB01-E/MG pinout, MCP48CMB01-E/MG application, or MCP48CMB01-E/MG equivalent, key selection criteria include its MTP memory (32 write cycles, 8 GP locations), 1 LSb INL specification, dual power-down resistor options (100 kΩ/1 kΩ), and extended temperature range (–40°C to +125°C) for industrial embedded systems.
Technical Context
The MCP48CMB01-E/MG implements a resistor ladder architecture with buffered op-amp output, supporting three reference sources (VDD, external VREF, or internal 1.214V band gap) and selectable 1× or 2× gain (when VREF ≠ VDD). Its SPI interface complies with modes '00' and '11', enabling up to 50 MHz write and 25 MHz read speeds.
Nonvolatile configuration and output values are stored in MTP memory, programmed via 7.5V on the LAT/HVC pin. Power-on/brown-out reset ensures deterministic startup, and WiperLock™ technology prevents unintended register changes during operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP48FVB01-E/MG | Volatile RAM only (no MTP); identical pinout, timing, and analog specs | Requires host MCU to reload DAC value at every power-up; unsuitable for unattended recalibration | Select when deterministic startup is not required and cost reduction is prioritized over nonvolatility |
| DAC8560IDBVT | 16-bit resolution, 2 LSB INL, 10 µs settling, I²C interface, no internal reference | Higher precision but lacks integrated reference and nonvolatile storage; requires external ref and EEPROM | Select when absolute accuracy >0.0015% FSR is mandatory and system already includes precision reference and NVM |
Compared with MCP48FVB01-E/MG, the MCP48CMB01-E/MG adds guaranteed power-up repeatability via MTP; compared with DAC8560IDBVT, it trades resolution for integration, reducing BOM count and layout complexity in cost-sensitive industrial controls.

FAQ
What is the maximum SPI clock frequency supported by the MCP48CMB01-E/MG?
The MCP48CMB01-E/MG supports up to 50 MHz for write operations and 25 MHz for read operations when VDD is 2.7V–5.5V. At reduced supply (1.8V–2.7V), maximum SPI frequency drops to 10 MHz. These speeds are validated across the full –40°C to +125°C temperature range and ensure reliable communication with modern MCUs without protocol translation.
How does the LAT/HVC pin function in the MCP48CMB01-E/MG?
The LAT/HVC pin serves two distinct roles in the MCP48CMB01-E/MG: as LAT, it latches the DAC output value; as HVC, it accepts 7.5V to enable MTP memory programming. The function is determined by applied voltage level-standard logic levels trigger latch behavior, while ≥7.25V triggers high-voltage programming mode. This dual functionality eliminates need for separate control lines.
Does the MCP48CMB01-E/MG include an internal voltage reference?
Yes, the MCP48CMB01-E/MG integrates a precision internal band gap reference of 1.214V (±0.03V over temperature), usable directly as the DAC reference source. This eliminates external reference components in cost-sensitive designs and maintains stability over –40°C to +125°C with 16 ppm/°C tempco.
What is the guaranteed integral nonlinearity (INL) specification for the MCP48CMB01-E/MG?
The MCP48CMB01-E/MG guarantees ±0.10 LSb integral nonlinearity across its full operating range (–40°C to +125°C, VDD = 2.7–5.5V). This corresponds to <0.04% of full-scale range and ensures monotonic behavior with no missing codes, critical for closed-loop control and calibration accuracy.
Can the MCP48CMB01-E/MG operate from a 1.8V supply?
The MCP48CMB01-E/MG supports 1.8V to 2.7V operation for SPI interface functionality only; analog specifications-including INL, settling time, and reference accuracy-are specified only for 2.7V–5.5V. Using 1.8V supply degrades analog performance and is not recommended for precision applications.
