Micropower Operation: 500 µA at 3 V VDD
The DAC6574 is a low-power, quad channel, 10-bit
Fast Update Rate: 188 kSPS
buffered voltage output DAC. Its on-chip precision

operation makes it ideally suited to portable battery
operated equipment. The power consumption is less
than 3mW at VDD = 5 V reducing to 1 µW in
power-down mode.
