The AD7398 / AD7399 family of quad, 12-bit/10-bit, voltage output digital-to-analog converters (DACs) is designed to operate from a single 3 V to 5 V supply or a dual ±5 V supply. Built with the Analog Devices, Inc. robust CBCMOS process, these monolithic DACs offer the user low cost with ease-of-use in single or dual-supply systems.
The applied external reference, VREF, determines the full-scale output voltage. Valid VREF values include VSS < VREF < VDD that result in a wide selection of full-scale outputs. For multiplying applications, ac inputs can be as large as ±5 VP.
A doubled-buffered serial-data interface offers high speed, 3-wire, SPI- and microcontroller-compatible inputs using serial data-in (SDI), clock (CLK), and a chip-select (CS). A common level-sensitive, load-DAC strobe (LDAC) input allows simultaneous update of all DAC outputs from previously loaded input registers. Additionally, an internal power-on reset forces the output voltage to zero at system turn on. An external asynchronous reset (RS) also forces all registers to the zero code state. A programmable power-shutdown feature reduces power dissipation on unused DACs.
Both parts are offered in the same pinout, enabling users to select the appropriate resolution for their application without redesigning the layout. For 8-bit resolution applications, see the pin-compatible AD7304 product.
The AD7398 / AD7399 are specified over the extended industrial (−40°C to +125°C) temperature range. Parts are available in 16-lead, wide body SOIC and ultracompact, thin, 1.1 mm TSSOP packages.

Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
