Frequently Asked Questions
How many bits of resolution does the DAC7822IRTATG4 have?
The DAC7822IRTATG4 is a 12-bit DAC, providing 4096 discrete output levels per channel. This resolution level is suitable for high-precision analog signal generation applications such as calibration references, waveform synthesis, and industrial process control requiring fine-grained output voltage control.
What input format does the DAC7822IRTATG4 use?
The DAC7822IRTATG4 uses a parallel word input format with binary input code. This allows the full 12-bit data word to be loaded simultaneously via a parallel bus interface, which is compatible with standard microcontroller, FPGA, and DSP data bus architectures for fast data updates.
What is the linearity error of the DAC7822IRTATG4?
The DAC7822IRTATG4 has a maximum linearity error of 0.0244%, which corresponds to approximately ±1 LSB at 12-bit resolution. This level of precision ensures accurate and repeatable analog output values, making it suitable for precision measurement, calibration, and control applications.
What package does the DAC7822IRTATG4 come in?
The DAC7822IRTATG4 is available in a 40-pin QFN (Quad Flat No-Lead) package. This compact surface-mount package offers excellent thermal performance and a small PCB footprint, making it well-suited for density-sensitive designs in industrial and measurement equipment.
What does multiplying DAC mean for the DAC7822IRTATG4?
A multiplying DAC allows the output to scale proportionally with an external reference voltage, not just an internal fixed reference. This means the DAC7822IRTATG4 can generate outputs that are a fraction of a varying external reference, enabling ratiometric measurement, programmable gain amplification, and dynamic signal scaling in analog signal processing chains.
