2.5 V to 5.5 V, 500 μA, Quad Voltage Output

8-/10-/12-Bit DACs in 10-Lead Packages

AD5304/AD5314/AD5324

Data Sheet

FEATURES

GENERAL DESCRIPTION

The AD5304/AD5314/AD5324¹are quad 8-, 10-, and 12-bit

AD5304: 4 buffered 8-Bit DACs in 10-lead MSOP and

buffered voltage output DACs in 10-lead MSOP and 10-lead

LFCSP packages that operate from a single 2.5 V to 5.5 V supply,

consuming 500 μA at 3 V. Their on-chip output amplifiers allow

rail-to-rail output swing to be achieved with a slew rate of 0.7 V/μs.

A 3-wire serial interface is used; it operates at clock rates up to

30 MHz and is compatible with standard SPI, QSPI, MICROWIRE,

and DSP interface standards.

10-lead LFCSP

A, W Version: 1 LSB INL, B Version: 0.625 LSB INL

AD5314: 4 buffered 10-Bit DACs in 10-lead MSOP and

10-lead LFCSP

A, W Version: 4 LSB INL, B Version: 2.5 LSB INL

AD5324: 4 buffered 12-Bit DACs in 10-lead MSOP and

10-lead LFCSP

A, W Version: 16 LSB INL, B Version: 10 LSB INL

Low power operation: 500 μA @ 3 V, 600 μA @ 5 V

2.5 V to 5.5 V power supply

Guaranteed monotonic by design over all codes

Power-down to 80 nA @ 3 V, 200 nA @ 5 V

Double-buffered input logic

The references for the four DACs are derived from one reference

pin. The outputs of all DACs can be updated simultaneously using

LDAC

the software

function. The parts incorporate a power-on

reset circuit, and ensure that the DAC outputs power 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 device to 200 nA @ 5 V (80 nA @ 3 V).

Output range: 0 V to V_REF

Power-on reset to 0 V

The low power consumption of these parts in normal operation

makes them ideally suited to portable battery-operated equipment.

The power consumption is 3 mW at 5 V, 1.5 mW at 3 V, reducing

to 1 μW in power-down mode.

LDAC

Simultaneous update of outputs (

function)

Low power-, SPI®-, QSPI™-, MICROWIRE™-, and DSP-

compatible 3-wire serial interface

On-chip, rail-to-rail output buffer amplifiers

Temperature range −40°C to +105°C

Qualified for automotive applications
