Frequently Asked Questions
How many DAC channels does the MCP4728A4T-E/UNVAO provide and what is its resolution?
The MCP4728A4T-E/UNVAO provides four independent DAC output channels, each with 12-bit resolution. This yields 4096 discrete output levels per channel, with a maximum output voltage of 5.5V and a maximum linearity error of 0.3174%. The quad architecture enables independent control of four analog signals from a single compact MSOP-10 package.
What is the benefit of the non-volatile memory in the MCP4728A4T-E/UNVAO?
The MCP4728A4T-E/UNVAO integrates EEPROM for each DAC channel, storing the output code that is automatically loaded at power-up. This eliminates the need for the host microcontroller to re-program the DAC after every reset or power cycle, simplifying firmware and ensuring correct analog outputs are available immediately at startup in automotive and industrial systems.
Is the MCP4728A4T-E/UNVAO qualified for automotive applications?
Yes, the 'A' suffix and 'Q' designation in MCP4728A4T-E/UNVAO indicate AEC-Q100 automotive qualification. The device operates from -40°C to +125°C (extended automotive temperature range per the -E suffix), making it suitable for use inside vehicle ECUs, climate control modules, and ADAS sensor assemblies subject to harsh thermal environments.
What package does the MCP4728A4T-E/UNVAO use?
The MCP4728A4T-E/UNVAO is packaged in an MSOP-10 (Mini Small Outline Package, 10-pin) surface mount format, designated JESD-30 code S-PDSO-G10. This compact package measures approximately 3mm x 3mm, making it one of the smallest footprints available for a quad DAC and enabling high-density PCB designs in space-constrained automotive modules.
What are common alternatives to the MCP4728A4T-E/UNVAO?
Alternatives include the Microchip MCP4726 (single-channel, 12-bit I2C DAC) and MCP4922 (dual SPI DAC without NV memory). For automotive quad DACs, the Texas Instruments DAC7578 (12-bit, I2C, 8-channel) and Maxim MAX5825 (12-bit, I2C, 8-channel with NV) are comparable, though package and NV feature availability may differ from the MCP4728.
