Description

The DAC0808 is an 8-bit monolithic digital-to-analog con- verter (DAC) featuring a full scale output current settling time of 150 ns while dissipating only 33 mW with 5V supplies. No reference current (IREF) trimming is required for most applications since the full scale output current is typically 1. LSB of 255 IREF/ 256. The DAC0800, the DAC0802 and the DAC0808 seem to suffer from the apparent need for bipolar supplies. But, by setting the negative supply to ground and shifting all other voltages up by 5 V, these. DACs will behave normally without a negative supply. The requirement is that all of the voltages associated with the DAC current-output digital-to-analog converters (DAC). Full Scale Error: 1 LSB featuring typical settling times of 100 ns. When used. Nonlinearity Over Temperature: 0.1% as a multiplying DAC, monotonic performance over a. 40 to 1 reference current range is possible. The. Full Scale Current Drift: 10 ppm/ C. DAC0800 ABSTRACT. This application report presents a method for interfacing the DAC8814 a four-channel, current output, 16-bit multiplying digital-to-analog converter to the. MSP430F449 processor using the HPA449 from SoftBaugh. The software developed creates a 256-point sine table, and then continuously writes values GENERAL DESCRIPTION. There has been a trend in recent years toward providing totally dedicated digital-to-analog converters with limited applications versatility. This application note describes a new type of monolithic DAC designed for an extremely broad range of applications, the Analog Devices DAG- 08. Several
