Frequently Asked Questions
What is the resolution and output voltage range of the DAC7811IDGSR?
The DAC7811IDGSR is a 12-bit DAC providing 4096 discrete output levels. Its analog output voltage range spans from -10V to +10V, enabling precise control over a wide signal range. Linearity error is specified at a maximum of 0.0244%, ensuring excellent accuracy for demanding applications.
What is the settling time of the DAC7811IDGSR and why does it matter?
The DAC7811IDGSR features a settling time of 0.2µs (200 nanoseconds), which is the time required for the output to reach and stay within the specified accuracy band after a code change. This ultra-fast settling time is critical for high-speed waveform generation, scanning systems, and real-time control loops where rapid output updates are necessary.
What interface does the DAC7811IDGSR use and how does it connect to a microcontroller?
The DAC7811IDGSR uses a serial input interface with binary input format, compatible with standard SPI communication. It connects to a microcontroller via standard SPI pins (SDI, SCK, and CS/SYNC), requiring only three digital lines. This minimizes PCB routing complexity and makes it easy to integrate into embedded systems.
What package is the DAC7811IDGSR available in and what are its dimensions?
The DAC7811IDGSR is housed in a 10-pin MSOP (Micro Small Outline Package) identified by the DGSR suffix and JESD-30 code S-PDSO-G10. This compact surface-mount package is ideal for space-constrained PCB designs. It is RoHS-compliant (Pbfree Code: Yes) with a JESD-609 code of e4, confirming lead-free construction.
What are typical applications for the DAC7811IDGSR?
The DAC7811IDGSR is commonly used in industrial process control, programmable power supplies, precision test and measurement instruments, medical devices, and motor drive systems. Its multiplying DAC architecture also makes it suitable for automatic gain control (AGC) circuits and digitally-controlled attenuation in audio and communications equipment.
