概述

Description

The MCP4812-E/MS is Microchip’s dual 8-bit voltage-output DAC. It accepts two independent 8-bit digital codes via a serial SPI-compatible interface and converts them to two buffered analog voltages (VOUTA and VOUTB). The LDAC feature allows simultaneous updating of both outputs when desired. The device is designed for embedded and test applications where two precise, controllable voltages are needed.
Key points:
- Dual-channel, 8-bit resolution
- SPI-compatible serial input (with CS, SCK, DI)
- Two buffered outputs (VOUTA, VOUTB)
- LDAC for simultaneous update
- Operating supply typically 2.7–5.5 V
- -E denotes extended temperature variant; package is MSOP (MS suffix)
Applications: waveform generation, precision control loops, calibration, and lab/test equipment.
Note: Refer to the MCP4812 datasheet for exact electrical specs (settling time, accuracy, reference requirements, and pinout) for your specific operating conditions.

Package

MCP4812-E/MS comes in an MSOP-8 package (8-pin Micro Small Outline Package) with extended temperature range (-40°C to +125°C).

Pinout

- Pin count: 8 pins.
- Function: Dual 8-bit voltage-output DAC with SPI-compatible interface. Provides two buffered outputs (VOUTA and VOUTB). Control via CS, SCK, SDI, and LDAC; power pins are VDD and VSS. Uses VDD as the reference (no dedicated VREF pins). The E/MS suffix indicates an extended-temperature MSOP-8 package.

Manufacturer

- Manufacturer: Microchip Technology Inc.
- What kind of company: A global semiconductor company that designs, manufactures, and sells microcontrollers, analog and memory devices, and other embedded-system ICs.

Application

Applications:
- Embedded control: DC setpoints and reference voltages
- Industrial automation and process control (sensor/actuator interfaces, feedback)
- Motor/servo control and position/speed references
- Test, measurement, calibration equipment (signal generation, stimuli)
- Data acquisition and lab instrumentation (waveform generation, DAC stimuli)
- Sensor simulation and prototyping
Notes: MCP4812-E/MS is a dual 8-bit, buffered DAC with SPI interface and extended temperature range.

Equivalent

The MCP4812-E/MS is a dual 8‑bit SPI DAC with buffered outputs. Equivalents from other vendors include:
- Analog Devices AD8402 (dual 8‑bit voltage-output DAC with SPI)
- Texas Instruments DAC7612 (dual 8‑bit SPI DAC)
Other 2‑channel 8‑bit SPI DACs from TI/Analog Devices can substitute; ensure matching pinout, reference voltage, and packaging.
