GENERAL DESCRIPTION

The AD5602/AD5612/AD5622, members of the nanoDAC

family, are single 8-, 10-, 12-bit buffered voltage-out DACs that

operate from a single 2.7 V to 5.5 V supply, consuming <100 μA

at 5 V. These DACs come in tiny SC70 packages. Each DAC

contains an on-chip precision output amplifier that allows rail-

to-rail output swing to be achieved.

The AD5602/AD5612/AD5622 use a 2-wire I

serial interface that operates in standard (100 kHz), fast

(400 kHz), and high speed (3.4 MHz) modes.

The references for AD5602/AD5612/AD5622 are derived from

the power supply inputs to give the widest dynamic output range.

Each part incorporates a power-on reset circuit that ensures the

DAC output powers up to 0 V and remains there until a valid

write takes place to the device. The parts contain a power-down

feature that reduces the current consumption of the devices to

<150 nA at 3 V and provides software-selectable output loads

while in power-down mode. The parts are put into power-down

mode over the serial interface. The low power consumption of

the AD5602/AD5612/AD5622 in normal operation makes them

ideally suited for use in portable battery-operated equipment. The

typical power consumption is 0.4 mW at 5 V.

PRODUCT HIGHLIGHTS

ADDR

Available in a 6-lead SC70 package.

Maximum 100 μA power consumption, single-supply

operation. These parts operate from a single 2.7 V to 5.5 V

supply, typically consuming 0.2 mW at 3 V and 0.4 mW at

5 V, making them ideal for battery-powered applications.

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.

Reference derived from the power supply.

Standard, fast, and high speed mode I

Designed for very low power consumption.

Power-down capability. When powered down, the DAC

typically consumes <150 nA at 3 V.
