DESCRIPTION

The DAC5571 is a low-power, single-channel, 8-bit

buffered voltage output DAC. Its on-chip precision

output amplifier allows rail-to-rail output swing to be

achieved. The DAC5571 utilizes an I²C-compatible,

two-wire serial interface that operates at clock rates

up to 3.4 Mbps with address support of up to two

DAC5571s on the same data bus.

The output voltage range of the DAC is 0 V to VDD.

The DAC5571 incorporates a power-on-reset circuit

that ensures that the DAC output powers up at zero

volts and remains there until a valid write to the

device takes place. The DAC5571 contains a

power-down feature, accessed via the internal control

device to 50 nA at 5 V.

The low-power consumption of this part in normal

operation makes it ideally suited for portable battery

operated equipment. The power consumption is less

than 0.7 mW at VDD= 5 V reducing to 1 µW in power-down mode.

DAC7571/6571/5571 are 12/10/8-bit, single-channel

I²C DACs from the same family. DAC7574/6574/5574

and DAC7573/6573/5573 are 12/10/8-bit 2

quad-channel I C DACs. Also see DAC8571/8574 for

single/quad-channel, 16-bit I²C DACs.
