FEATURES

DESCRIPTION

The

DAC8564

is

a

low-power,

voltage-output,

234

•

Relative Accuracy: 4LSB

four-channel, 16-bit digital-to-analog converter (DAC).

•

Glitch Energy: 0.15nV-s

The

device

includes

a

2.5V,

2ppm/

°C

internal

•

Internal Reference:

reference (enabled by default), giving a full-scale

output voltage range of 2.5V. The internal reference

– 2.5V Reference Voltage (enabled by default)

has an initial accuracy of 0.004% and can source up

– 0.004% Initial Accuracy (typ)

– 2ppm/°C Temperature Drift (typ)

monotonic,

provides

very

good

linearity,

and

minimizes undesired code-to-code transient voltages

– 5ppm/°C Temperature Drift (max)

(glitch). The DAC8564 uses a versatile 3-wire serial

– 20mA Sink/Source Capability

interface that operates at clock rates up to 50MHz.

•

Power-On Reset to Zero-Scale

The interface is compatible with standard SPI

™,

QSPI

™, Microwire™, and digital signal processor

•

Ultra-Low Power Operation: 1mA at 5V

(DSP) interfaces.

•

Wide Power Supply Range: +2.7V to +5.5V

The DAC8564 incorporates a power-on-reset circuit

•

16-Bit Monotonic Over Temperature Range

that ensures the DAC output powers up at zero-scale

•

Settling Time: 10

μs to ±0.003% Full-Scale

and remains there until a valid code is written to the

Range (FSR)

device. The device contains a power-down feature,

•

Low-Power Serial Interface with

accessed over the serial interface, that reduces the

Schmitt-Triggered Inputs: Up to 50MHz

current consumption of the device to 1.3

μA at 5V.

Power consumption is 2.9mW at 3V, reducing to

•

On-Chip Output Buffer Amplifier with

1.5

μW

in

power-down

mode.

The

low-power

Rail-to-Rail Operation

consumption, internal reference, and small footprint

•

1.8V to 5.5V Logic Compatibility

make this device ideal for portable, battery-operated

•

Temperature Range:

–40°C to +105°C

equipment.

The DAC8564 is drop-in and functionally compatible
