Replaced By DAC8811 – The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.
TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.
The DAC8581 is a 16-bit, high-speed, low-noise DAC operating from dual ±5-V power supplies. The DAC8581 is monotonic, and has exceptionally low noise and exceptionally low glitch. The DAC8581 high-performance, bipolar output buffer is capable of settling within 0.65 µs for a 10-V step. Small-signal settling time is well under 0.3 µs, supporting data update rates up to 3 MSPS. A power-on-reset circuit sets the output at midscale voltage on power up.
The DAC8581 is simple to use, with a single external reference and a standard 3-wire SPI interface that allows clock rates up to 50 MHz.
Also see the DAC8580, a member of the same family. The DAC8580 combines DAC8581 performance with an on-chip, 16x over-sampling digital filter.
The DAC8581 is specified over the –40°C to +85°C temperature range.
