Product details
Overview
MCP48CMD02-E/MG from Microchip Technology is a dual-channel, 8-bit buffered voltage-output DAC with nonvolatile MTP memory (32 write cycles), SPI interface (50 MHz write), and selectable reference sources (VDD, external VREF, or internal 1.214 V bandgap). It operates from 2.7V to 5.5V and supports -40°C to +125°C, enabling precision analog output in sensor calibration and industrial control loops.
For engineers reviewing the MCP48CMD02-E/MG datasheet, MCP48CMD02-E/MG pinout, MCP48CMD02-E/MG application, or MCP48CMD02-E/MG equivalent, key selection criteria include dual 8-bit resolution with ±0.5 LSb INL, MTP-configurable power-up values, 4 µs settling time, and QFN-16 (3×3 mm) package compatibility with high-density PCB layouts.
Technical Context
The MCP48CMD02-E/MG implements a resistor ladder architecture with two independent buffered voltage outputs (VOUT0/VOUT1), each driven by its own op-amp stage. Its SPI interface supports both '00' and '11' clock modes and includes dedicated LAT/HVC pin for MTP programming at 7.5 V.
Reference selection is controlled via VRxB:VRxA bits: mode '10' uses VDD as reference with unity gain; mode '11' enables 2× gain with external VREF ≤ VDD/2; mode '01' selects internal 1.214 V bandgap. Power-down modes disconnect output buffers and configure 100 kΩ or 1 kΩ pull-down resistors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel 8-bit DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP48FVD02-E/MG | Volatile RAM only (no MTP); identical pinout, timing, and analog specs | Requires external nonvolatile storage for power-up values; unsuitable for standalone calibration retention | Choose when firmware handles initialization and MTP write endurance is not required |
| AD5662BRMZ-1REEL7 | Single-channel, 16-bit, SPI, internal 2.5 V reference; different pinout (10-lead MSOP) | Higher resolution but no dual output; lacks MTP for configuration storage | Choose when 16-bit precision is mandatory and dual channels can be implemented with two devices |
Compared with MCP48FVD02-E/MG, the MCP48CMD02-E/MG adds MTP-based power-up value retention without sacrificing speed or linearity; compared with AD5662BRMZ-1REEL7, it offers true dual-channel integration and smaller footprint, trading resolution for system-level simplicity and cost efficiency.

FAQ
What is the maximum SPI clock frequency supported by the MCP48CMD02-E/MG?
The MCP48CMD02-E/MG supports SPI write operations up to 50 MHz and read operations up to 25 MHz. This high-speed interface enables rapid DAC updates in time-critical applications such as motor control and real-time waveform generation. The device complies with standard SPI '00' and '11' modes, ensuring compatibility with most microcontroller SPI peripherals. Timing margins are validated across the full -40°C to +125°C temperature range.
Does the MCP48CMD02-E/MG require an external reference voltage?
No, the MCP48CMD02-E/MG does not require an external reference voltage. It supports three reference sources: the device VDD supply, an external voltage applied to the VREF pin (buffered or unbuffered), or the internal 1.214 V bandgap reference. When using VDD as reference, the internal circuitry connects VDD directly to the DAC reference path. The internal bandgap option eliminates external component count and provides stable 1.214 V ±2.5% over temperature.
How many times can the MTP memory in the MCP48CMD02-E/MG be programmed?
The MTP memory in the MCP48CMD02-E/MG supports up to 32 write cycles per memory location. This includes storage of power-up DAC output values, device configuration registers, and eight general-purpose memory locations. After the 32nd write, further programming attempts are ignored and the last written value is retained. The LAT/HVC pin must be driven to 7.5 V (±0.25 V) during programming, and the write cycle time is 250 µs per location.
What is the settling time specification for the MCP48CMD02-E/MG?
The MCP48CMD02-E/MG has a settling time of 4 µs to within ±1/2 LSb of final value for major code transitions (e.g., 400h to C00h in 12-bit mode). For its native 8-bit resolution, this ensures full-scale transitions settle reliably within the specified window under RL = 2 kΩ and CL = 100 pF loading. The fast settling is enabled by the integrated rail-to-rail output amplifier with 0.7 V/µs slew rate and 270 kHz –3 dB bandwidth.
Is the MCP48CMD02-E/MG pin-compatible with other devices in the MCP48CXDX family?
Yes, the MCP48CMD02-E/MG in the QFN-16 package is pin-compatible with all other MCP48CXDX2 dual-channel variants sharing the same package type, including MCP48CVD02-E/MG, MCP48CMD12-E/MG, and MCP48CMD22-E/MG. Pin functions (VREF, CS, VOUT0, SCK, LAT/HVC, VSS, SDI, VDD, VOUT1, SDO) are identical across these parts. Resolution and memory type differ, but PCB layout and firmware SPI interface remain unchanged - enabling design reuse and variant scalability.
