Product details

Four 16-bit channels on one SPI bus

The Texas Instruments DAC7634EB packs four independent 16-bit voltage-output DACs into a single 48-SSOP package, each channel addressed over a shared SPI interface.

Supply rails and temperature range

Analog section runs on ±5 V, the digital core on a separate 5 V supply. That split-rail requirement is the main PSU constraint — the analog rail needs a bipolar supply, so a single +5 V rail won't cut it.

Linearity and interface

INL is ±2 LSB, DNL ±1 LSB — typical for a 16-bit R-2R DAC and sufficient for most closed-loop analog outputs without external calibration. The SPI interface uses an external reference, so the reference voltage directly sets the output span; pick a low-drift reference if the application demands better than 16-bit accuracy over temperature.

Active and available

Lifecycle status is Active and ROHS3 compliant.

Frequently asked questions

What is the output type of DAC7634EB?

The output type is Voltage - Buffered. Each of the four DAC channels provides a buffered voltage output, not a current output.

Does DAC7634EB have a direct equivalent or second source?

No pin-compatible second source is listed in the official records. The DAC7750IPWP is a different device — it is a single-channel 12-bit current-output DAC with a wider temperature range and internal reference, not a functional replacement for the quad 16-bit voltage-output DAC7634EB.

How to interface DAC7634EB with SPI?

The DAC7634EB uses a standard SPI data interface with an external reference. The digital supply is 5 V, so the SPI signals must be 5 V-compatible. For 3.3 V logic, a level shifter is required between the host controller and the DAC's digital inputs.
