Product details
Overview
MCP48CMD01-E/MF from Microchip Technology is a single-channel, 8-bit buffered voltage-output DAC with nonvolatile (MTP) memory, SPI interface, and 1 LSb integral nonlinearity. It operates from 2.7V to 5.5V, supports internal band gap (1.214V), VDD, or external VREF as reference source, and delivers ±0.5 LSb zero-scale error and 0.625 LSb full-scale error - used in precision sensor calibration and set-point trimming circuits.
For engineers reviewing the MCP48CMD01-E/MF datasheet, MCP48CMD01-E/MF pinout, MCP48CMD01-E/MF application, or MCP48CMD01-E/MF equivalent, key selection considerations include its MTP programmability (32 writes per location), 4 µs settling time, SPI write speed up to 50 MHz, dual power-down resistor options (100 kΩ/1 kΩ), and operation across –40°C to +125°C.
Technical Context
The MCP48CMD01-E/MF implements a resistor ladder architecture with buffered voltage output and WiperLock™ technology for register protection. Its SPI interface supports both '00' and '11' clock modes, enabling interoperability with diverse microcontroller platforms while maintaining 50 MHz write throughput.
Nonvolatile configuration storage includes power-up output values, device settings, and 8 general-purpose MTP locations. Programming requires 7.5V on the LAT/HVC pin, and the internal band gap reference provides 1.214V ±0.034V with 18 ppm/°C tempco - critical for stable output without external references.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP4725A0T-E/CH | I²C interface, 12-bit resolution, internal EEPROM (no HVC pin required), lower max VDD (5.5V same), no 2x gain option | Better suited for space-constrained I²C systems; lacks SPI speed and MTP flexibility for high-reliability field updates | Choose when I²C bus availability and 12-bit resolution outweigh need for fast SPI writes or programmable gain |
| AD5620BRJZ-REEL7 | 12-bit, SPI interface, internal 2.5V reference, no MTP, higher INL (±1 LSb), 10-lead SOT-23 package | Targeted at cost-sensitive, low-pin-count applications where nonvolatility is handled externally | Choose when internal 2.5V reference suffices and MTP is not required; verify 10-lead SOT-23 thermal performance vs. MSOP/DFN |
Compared with MCP4725A0T-E/CH and AD5620BRJZ-REEL7, the MCP48CMD01-E/MF uniquely combines 8-bit precision with on-chip MTP, 2x gain capability, and 50 MHz SPI - making it optimal for embedded systems requiring robust, field-updatable analog output without external memory or reference components.

FAQ
What is the maximum SPI clock frequency supported by the MCP48CMD01-E/MF?
The MCP48CMD01-E/MF supports SPI write operations up to 50 MHz and read operations up to 25 MHz. This high-speed interface reduces host processor overhead during rapid DAC updates, such as in waveform generation or real-time control loops. The device complies with standard SPI '00' and '11' modes, ensuring compatibility with most microcontrollers without custom timing adjustments. All timing specifications are guaranteed across –40°C to +125°C.
Does the MCP48CMD01-E/MF require an external high-voltage supply for MTP programming?
Yes, the MCP48CMD01-E/MF requires a 7.5V (±0.25V) high-voltage signal applied to the LAT/HVC pin to initiate nonvolatile memory writes. This voltage is only needed during programming - not during normal operation. The device draws up to 6.4 mA during MTP write cycles, and the LAT/HVC pin must be returned to ≤5.5V after programming completes. No external charge pump or boost converter is integrated.
Can the MCP48CMD01-E/MF operate from a 1.8V supply?
No, the MCP48CMD01-E/MF does not support full-specification operation at 1.8V. Its minimum VDD for guaranteed analog performance is 2.7V. While the SPI interface may function down to 1.8V per reduced-spec mode, DAC linearity, INL, settling time, and reference accuracy are not characterized or guaranteed below 2.7V. For true 1.8V-compatible DACs, consider Microchip's MCP4728 or ADI's AD5689R families.
What is the purpose of the two power-down resistor options (100 kΩ and 1 kΩ) on the MCP48CMD01-E/MF?
The MCP48CMD01-E/MF offers selectable VOUT pull-down resistors (100 kΩ or 1 kΩ) in power-down mode to manage output behavior during sleep or fault conditions. The 100 kΩ option minimizes current draw for ultra-low-power retention, while the 1 kΩ option provides stronger sink capability to override external leakage or capacitive hold-up - critical in safety-critical systems where output must settle rapidly to a known state. Selection is controlled via PD1:PD0 bits in the configuration register.
How does the internal band gap reference perform over temperature on the MCP48CMD01-E/MF?
The MCP48CMD01-E/MF's internal band gap reference delivers 1.214V ±0.034V (1.180V to 1.260V) over 1.8V ≤ VDD ≤ 5.5V, with a temperature coefficient of ±18 ppm/°C. This stability ensures consistent DAC output scaling across –40°C to +125°C without external components. Load regulation is specified at 52 µV/mA (sourcing) and 374 µV/mA (sinking), supporting direct connection to moderate-impedance loads without buffering.
