DAC8564

SBAS403A – JUNE 2007 – REVISED NOVEMBER 2007

16-Bit, Quad Channel, Ultra-Low Glitch, Voltage Output

DIGITAL-TO-ANALOG CONVERTER with 2.5V, 2ppm/

°C Internal Reference

234

• Relative Accuracy: 4LSB

The

DAC8564

is

a

low-power,

voltage-output,

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

• Glitch Energy: 0.15nV-s

The

device

includes

–

20mA Sink/Source Capability

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

interface that operates at clock rates up to 50MHz.

• Power-On Reset to Zero-Scale

The interface is compatible with standard SPI™,

• Ultra-Low Power Operation: 1mA at 5V

QSPI™, Microwire™, and digital signal processor

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

(DSP) interfaces.

• 16-Bit Monotonic Over Temperature Range

The DAC8564 incorporates a power-on-reset circuit

• Settling Time: 10µs to ±0.003% Full-Scale

that ensures the DAC output powers up at zero-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

current consumption of the device to 1.3

µA at 5V.

• On-Chip Output Buffer Amplifier with

The low-power consumption, internal reference, and

Rail-to-Rail Operation

small footprint make this device ideal for portable,

battery-operated equipment. The power consumption

• Drop-In and Functionally Compatible with

is 2.9mW at 3V, reducing to 1.5

µW in power-down

DAC8534 and DAC8554

mode.

• Pin-Compatible with DAC8555 and DAC8565

The DAC8564 is drop-in and functionally compatible

• 1.8V to 5.5V Logic Compatibility

with the DAC8534 and DAC8554, and pin-compatible

• Temperature Range: –40°C to +105°C

with DAC8555 and DAC8565. The DAC8564 is

available in a TSSOP-16 package.
