Product Introduction

Overview

The AD5308BRU-REEL7 is an octal 8-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Analog Devices Inc. This component is part of the AD5308/AD5318/AD5328 family, which includes 8-, 10-, and 12-bit resolutions, respectively. The AD5308BRU-REEL7 operates from a single supply voltage ranging from 2.5 V to 5.5 V and is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP). It is designed for high-performance applications requiring precise and reliable digital-to-analog conversion.

Key Features

  • Octal DAC with 8-bit resolution, providing eight independent voltage output channels.
  • On-chip output amplifiers with rail-to-rail output swing and a slew rate of 0.7 V/μs.
  • Versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, operating at clock rates up to 30 MHz.
  • Reference inputs can be configured as buffered, unbuffered, or VDD inputs.
  • Power-on reset circuit ensures DAC outputs power up to 0 V and remain there until a valid write.
  • Individual power-down feature for each DAC, reducing current consumption to 400 nA at 5 V (120 nA at 3 V).
  • Simultaneous update of all DAC outputs using the asynchronous LDAC input.

Applications

  • Optical networking
  • Automatic test equipment
  • Mobile communications
  • Programmable attenuators
  • Industrial process control
