Overview

The DAC80508ZRTET is a highly integrated, low-power, 16-bit digital-to-analog converter featuring eight buffered voltage output channels. It includes an internal 2.5V reference and operates from a single 2.7V to 5.5V supply, making it ideal for high-density systems requiring precision analog control in a compact 3x3mm footprint.

Why Choose This Part

This DAC offers excellent linearity with INL and DNL of +/-0.5 LSB and a very low power consumption of 0.6 mA per channel. The inclusion of a 50MHz SPI interface with CRC error checking and daisy-chain capability ensures robust and efficient communication in multi-channel systems.

Applications

Optical Networking
Precise control of Mach-Zehnder modulators and optical attenuators in high-speed communication infrastructure.
Industrial Automation
Programmable logic controllers (PLCs) and distributed control systems (DCS) requiring high-density analog outputs.
Wireless Infrastructure
Bias control for power amplifiers and antenna beamforming applications in cellular base stations.
Test and Measurement
Generating precise DC setpoints and calibration voltages for automated test equipment.

Getting Started

Evaluate the device using the DAC80508EVM evaluation module, which connects to the TI Precision Host Interface (PHI) for software-based configuration. For firmware development, utilize the standard SPI protocol to access the internal 2.5V reference and gain settings, ensuring the LDAC pin is managed for synchronous channel updates.
