Frequently Asked Questions
What is the resolution and output voltage range of the DAC8551AQDGKRQ1?
The DAC8551AQDGKRQ1 is a 16-bit DAC providing 65,536 discrete output levels. The analog output voltage range spans from 0V to VREF, where VREF can be up to the supply voltage (maximum 5.5V). This gives a minimum LSB step size of approximately 76µV with a 5V reference, making it suitable for high-precision automotive control applications.
What communication interface does the DAC8551AQDGKRQ1 use and how fast is it?
The DAC8551AQDGKRQ1 uses a 3-wire SPI-compatible serial interface supporting clock speeds up to 50MHz. It accepts a 24-bit input word comprising two power-down control bits and 16 data bits. This standard interface makes it easy to connect to virtually any automotive-grade microcontroller or DSP without additional logic.
Is the DAC8551AQDGKRQ1 AEC-Q100 qualified for automotive use?
Yes, the DAC8551AQDGKRQ1 carries the AEC-Q100 automotive qualification and is rated for the extended temperature range of -40°C to +125°C. The -Q1 suffix in the part number designates it as an automotive-grade device, making it appropriate for under-hood and other harsh automotive environments where reliability over lifetime is mandatory.
What package does the DAC8551AQDGKRQ1 come in and what are the ordering options?
The DAC8551AQDGKRQ1 is supplied in an 8-pin VSSOP (MSOP-8) small-outline package with a 0.65mm pitch. The 'Q1' suffix confirms automotive grade, 'DGK' is the VSSOP package designator, and 'R' indicates tape-and-reel packaging. Tape-and-reel quantities are typically 2,500 pieces per reel, suitable for automated SMT production lines.
What are common alternatives or pin-compatible replacements for the DAC8551AQDGKRQ1?
Common alternatives include the DAC8531 (16-bit, non-automotive, lower cost) and the DAC7571 (12-bit, I2C interface). For automotive drop-in replacements, the DAC8551IBDGKR is the industrial-grade version with identical pinout and electrical characteristics. If higher channel count is needed, the DAC8562-Q1 (dual 16-bit) or DAC8168-Q1 (octal 16-bit) offer pin-compatible migration paths within the same TI family.
