MAX5805BAUB+T

MAX5805BAUB+T is a Maxim Integrated (now Analog Devices) multi-channel digital-to-analog converter (DAC) with a serial interface. It converts digital words into precise analog outputs across its channels, making it suitable for programmable analog outputs in instrumentation, calibration, and control systems.
Key points
- Serial interface: SPI-compatible data transfer to set DAC codes.
- Multi-channel: provides several independent analog outputs from a single device.
- Output and performance: designed for low-noise, stable analog signals; may offer options for internal reference and output buffering.
- Power and packaging: operates from a defined supply range; -T denotes tape-and-reel packaging; -BAUB is the RoHS-compliant package code.
Usage overview
- Connect supply (VDD) and ground.
- Use SCLK, MOSI/SDI, and CS to program the DAC codes; LDAC (if present) updates outputs.
- Optional REF connections if using an external reference.
For exact specs (resolution, output range, timing, current/voltage behavior, and recommended schematics), refer to the MAX5805 datasheet and package/ordering guide. If you share your application, I can tailor the overview.

To give accurate equivalents, I need the MAX5805’s function and specs (DAC/ADC, resolution, interface, channels, supply, package). Do you want a pin‑for‑pin drop‑in or just any equivalent? For SPI DACs with similar use, candidates include TI DAC7571/7574, Analog Devices AD5662/AD5665, Microchip MCP4921/4922, and other Maxim parts. Share your required specs and I’ll deliver a precise cross reference.

I don’t have the MAX5805BAUB+T datasheet loaded. Please share a link or confirm the exact variant for precise features.
Typical MAX5805-series features (general, not variant-specific):
- SPI-compatible serial interface
- DAC resolution around 12–14 bits
