SBAS411C –JUNE 2007–REVISED MARCH 2011

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

Digital-to-Analog Converter with 2.5V, 2ppm/°C Internal Reference

Check for Samples: DAC8565

FEATURES

DESCRIPTION

The DAC8565 is

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

The device includes 2.5V, 2ppm/°C internal

low-power, voltage-output,

234

•

Relative Accuracy: 4LSB

Glitch Energy: 0.15nV-s

Internal Reference:

•

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

output voltage range of 2.5V. The internal reference

has an initial accuracy of 0.004% and can source up

to 20mA at the V_REFH/V_REFOUT pin. The device is

monotonic, provides very good linearity, and

minimizes undesired code-to-code transient voltages

(glitch). The DAC8565 use a versatile 3-wire serial

interface that operates at clock rates up to 50MHz. It

is compatible with standard SPI™, QSPI™,

Microwire™, and digital signal processor (DSP)

interfaces.

20mA Sink/Source Capability

•

Power-On Reset to Zero-Scale or Midscale

Asynchronous Clear to Zero-Scale or Midscale

Ultra-Low Power Operation: 1mA at 5V

The DAC8565 incorporates a power-on-reset circuit

that ensures the DAC output powers up at either

zero-scale or midscale until a valid code is written to

the device. The device contains a power-down

feature, accessed over the serial interface, that

reduces the current consumption of the device to

1.3μA at 5V. The low power consumption, internal

reference, and small footprint make this device ideal

for portable, battery-operated equipment. The power

consumption is 2.9mW at 3V, reducing to 1.5μW in

power-down mode.

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

16-Bit Monotonic Over Temperature Range

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

Range (FSR)

•

Low-Power Serial Interface with

Schmitt-Triggered Inputs: Up to 50MHz

On-Chip Output Buffer Amplifier with

Rail-to-Rail Operation

•

1.8V to 5.5V Logic Compatibility

Temperature Range: –40°C to +105°C

The DAC8565 is drop-in and functionally compatible

with the DAC7564 and DAC8164, and functionally

compatible with the DAC7565, DAC8165, and

DAC8564. All these devices are available in a

TSSOP-16 package.
