Visão Geral
Description
Key points:
- Interface: I2C (two‑wire) with address select (A0–A2) for multiple devices on a bus.
- Resolution: 8 bits per channel; separate or simultaneous updates possible.
- Outputs: Two independently programmable, buffered voltage outputs.
- Packaging: MSOP‑8 package; -E indicates extended/industrial temperature grade; -MS denotes MSOP.
- Applications: precision voltage generation for instrumentation, calibration, test benches, and control loops.
Note: See the MCP4812 datasheet for exact timing, command map, and electrical specs.
Equivalent
- Microchip MCP4902 (dual 8‑bit SPI DAC)
- Analog Devices AD7302 (dual 8‑bit SPI DAC)
Ensure matching supply (typically 2.7–5.5V), reference voltage, output range, and pinout before substitution.
Pinout
- Function: Dual 8‑bit digital-to-analog converter (DAC) with an I2C‑compatible serial interface, providing two analog outputs (VoutA and VoutB) controlled via I2C.
Manufacturer
- What kind of company: A global semiconductor company that designs, develops, and manufactures microcontrollers, analog ICs, and memory products for embedded control and other electronics applications.
Application
- Industrial automation: dual analog setpoints for valves, actuators, or motor controllers.
- Instrumentation and test equipment: programmable voltage references, calibration sources, dual signal generation.
- Data acquisition and lab benches: sensor simulation, offset/gain adjustments, simple analog sources.
- Embedded/education and prototyping: microcontroller projects needing two DAC outputs via I2C.
In short: compact, dual-channel voltage outputs for precise, programmable analog signals in control, test, and research applications.
