+2.5 V to +5.5 V, 120 ␮A, 2-Wire Interface,

Voltage Output 8-/10-/12-Bit DACs

AD5301/AD5311/AD5321*

GENERAL DESCRIPTION

FEATURES

The AD5301/AD5311/AD5321 are single 8-, 10- and 12-bit

buffered voltage-output DACs that operate from a single +2.5 V

to +5.5 V supply consuming 120 µA at 3 V. The on-chip output

amplifier allows rail-to-rail output swing with a slew rate of

0.7 V/µs. It uses a 2-wire (I²C compatible) serial interface that

operates at clock rates up to 400 kHz. Multiple devices can

share the same bus.

AD5301: Buffered Voltage Output 8-Bit DAC

AD5311: Buffered Voltage Output 10-Bit DAC

AD5321: Buffered Voltage Output 12-Bit DAC

6-Lead SOT-23 and 8-Lead ␮SOIC Packages

Micropower Operation: 120 ␮A @ 3 V

2-Wire (I²C^®Compatible) Serial Interface

Data Readback Capability

+2.5 V to +5.5 V Power Supply

Guaranteed Monotonic By Design Over All Codes

Power-Down to 50 nA @ 3 V

Reference Derived from Power Supply

Power-On-Reset to Zero Volts

On-Chip Rail-to-Rail Output Buffer Amplifier

Three Power-Down Functions

The reference for the DAC is derived from the power supply

inputs and thus gives the widest dynamic output range. These

parts incorporate a power-on-reset circuit, which ensures that

the DAC output powers-up to zero volts and remains there until

a valid write takes place. The parts contain a power-down feature

which reduces the current consumption of the device to 50 nA

at 3 V and provides software-selectable output loads while in

power-down mode.

APPLICATIONS

Portable Battery Powered Instruments

Digital Gain and Offset Adjustment

Programmable Voltage and Current Sources

Programmable Attenuators

The low power consumption in normal operation make these

DACs ideally suited to portable battery-operated equipment.

The power consumption is 0.75 mW at 5 V, 0.36 mW at 3 V

reducing to 1 µW in all power-down modes.
