PRODUCT OVERVIEW

What Is the DAC7734EB?

DAC7734EB is a 16-bit, quad voltage output, serial input digital-to-analog converter (DAC) from Texas Instruments (Burr-Brown). The device provides 16-bit monotonic performance over the specified temperature range and features four independent voltage output DAC channels in a single package.

The DAC7734EB offers bipolar and unipolar output polarity with a buffered voltage output. The output amplifier can swing to within 1.5V of the positive supply rail and to within 1.5V of the negative supply rail. The digital input is a 24-bit serial word that contains a 2-bit address code for selecting one of four DACs, a quick load bit, and the 16-bit DAC code (MSB first). The device supports daisy-chaining by connecting the SDO pin of one device to the SDI pin of the following device in the chain.

The DAC7734EB operates with a dual supply voltage of ±14.25V to ±15.75V (analog) and a 5V digital supply. It features a settling time of 10µs to 0.003% FSR and low power consumption of 200mW maximum. The device is available in a 48-lead SSOP package (0.295", 7.50mm width), rated for operation from –40°C to +85°C. The device is RoHS compliant, REACH unaffected, and in active production.

16-Bit Quad-Channel DAC Four independent 16-bit voltage output DAC channels with ensured monotonic performance over the specified temperature range.

Serial Input & SPI Interface 24-bit serial word input with 2-bit address code, quick load bit, and 16-bit DAC code. SPI-compatible interface with daisy-chain capability.

Bipolar & Unipolar Output ±10V output range with buffered voltage output, supporting both bipolar and unipolar configurations.

DESIGN REFERENCE

Circuit Considerations for DAC7734EB

Serial Interface & Data Format

The DAC7734EB uses a 24-bit serial word for DAC programming:

24-Bit Serial Word: Contains a 2-bit address code for selecting one of four DACs, a quick load bit, five unused bits, and the 16-bit DAC code (MSB first)
Address Code: 2-bit code selects one of four DAC channels
Quick Load Bit: Enables simultaneous loading of multiple DACs
Daisy-Chain: Connect SDO pin of one device to SDI pin of the next device for multi-device chains
SPI Compatible: Standard SPI-compatible serial interface

PCB and System-Level Guidance

DAC performance depends on layout and component selection:

Decoupling Capacitors: Place 0.1µF and 10µF capacitors close to the V_DD and V_SS pins for stable operation
External Reference: Requires an external voltage reference for accurate operation
Output Buffer: On-chip rail-to-rail output buffer amplifier with output swing to within 1.5V of supply rails
Daisy-Chain Layout: Route SDO-to-SDI connections between devices for multi-DAC systems
Verify the recommended PCB footprint from the official datasheet prior to production
