DESCRIPTION

The DAC8580 is a 16-bit, high-speed, low-noise,

voltage-output DAC designed for waveform

generation applications. It operates from dual ±5-V

power supplies and requires only a single external

reference. The DAC8580 is capable of generating

output signal frequencies up to 1 MHz. The DAC8580

significantly relaxes, or removes, the need for

external de-glitchers, analog filters and high-swing

output buffers. It incorporates a programmable digital

interpolation filter capable of oversampling the input

word rate by 2, 4, 8, or 16. The digital filter can be

bypassed on-the-fly, or can be permanently turned

off. The fast 30-MHz serial interface is compatible

with right-justified digital audio format. The DAC8580

is specified from –40°C to 85°C.
