Frequently Asked Questions
What is the resolution and maximum sample rate of the DAC7545LUG4?
The DAC7545LUG4 is a 12-bit DAC with a maximum throughput rate of 500 ksps (kilo-samples per second), providing a good balance of resolution and speed for industrial control, signal synthesis, and test equipment applications.
What input code formats does the DAC7545LUG4 support?
It supports offset binary and 2's complement binary input codes via a parallel word interface, making it compatible with a wide range of microcontrollers, DSPs, and FPGAs that output data in either signed or unsigned integer formats.
What is the linearity accuracy of the DAC7545LUG4?
The maximum linearity error (EL) is 0.0122%, which corresponds to approximately 0.5 LSB at 12-bit resolution. This precision makes it suitable for applications requiring accurate analog representation of digital control signals in process control and instrumentation.
What package does the DAC7545LUG4 come in and is it RoHS compliant?
The DAC7545LUG4 is housed in a 20-pin SOIC package (JESD-30 code R-PDSO-G20). The JESD-609 e4 code confirms it is fully lead-free and RoHS compliant, and the Pb-free code further verifies suitability for environmentally regulated production.
Why choose a parallel interface DAC like the DAC7545LUG4 over a serial interface DAC?
A parallel interface DAC allows simultaneous loading of all 12 data bits in a single bus cycle, achieving maximum throughput without the latency associated with SPI or I2C serial clocking. This is advantageous in real-time control loops and waveform generation where update speed is critical and a parallel data bus is already available.
