DESCRIPTION

The DAC7568, DAC8168, and DAC8568 are

low-power, voltage-output, eight-channel, 12-, 14-,

and 16-bit digital-to-analog converters (DACs),

respectively. These devices include a 2.5V, 2ppm/°C

internal reference (disabled by default), giving a

full-scale output voltage range of 2.5V or 5V. The

internal reference has an initial accuracy of 0.004%

and can source up to 20mA at the V_REFIN/V_REFOUT

pin. These devices are monotonic, providing excellent

linearity and minimizing undesired code-to-code

transient voltages (glitch). They use a versatile 3-wire

serial interface that operates at clock rates up to

50MHz. The interface is compatible with standard

SPI™, QSPI™, Microwire™, and digital signal

processor (DSP) interfaces.

– 0.004% Initial Accuracy (typ)

– 2ppm/°C Temperature Drift (typ)

– 5ppm/°C Temperature Drift (max)

– 20mA Sink/Source Capability

•

Power-On Reset to Zero Scale or Midscale

Ultra-Low Power Operation: 1.25mA at 5V

Including Internal Reference Current

•

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

Monotonic Over Entire Temperature Range

Low-Power Serial Interface with

Schmitt-Triggered Inputs: Up to 50MHz

•

On-Chip Output Buffer Amplifier with

Rail-to-Rail Operation

The DAC7568, DAC8168, and DAC8568 incorporate

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. These devices

contain a power-down feature, accessed over the

serial interface, that reduces current consumption to

typically 0.18µA at 5V. Power consumption (including

internal reference) is typically 2.9mW at 3V, reducing

to less than 1µW in power-down mode. The low

power consumption, internal reference, and small

footprint make these devices ideal for portable,

battery-operated equipment.
