AD5601/AD5611/AD5621
Preliminary Technical Data
4.
5.
6.
Reference derived from the power supply.
PRODUCT HIGHLIGHTS
1.
Available in space saving 6-lead SC70 Package.
High speed serial interface with clock speeds up to 30 MHz.
2.
Low power, single-supply operation. This part operates from a single
2.7 V to 5.5 V supply and typically consumes 0.2 mW at 3 V and 0.5
mW at 5 V, making it ideal for battery-powered applications.
Designed for very low power consumption. The interface only powers
up during a write cycle.
7.
Power-down capability. When powered down, the DAC typically
consumes <100 nA at 3 V.
3.
The on-chip output buffer amplifier allows the output of the DAC to
swing rail-to-rail with a typical slew rate of
0.5 V/µs.
