10bit, Single Channel, 80uA, 2.0V-5.5V DAC in SC70 Package | DCK | 6 | -40 to 125

The 8-bit DAC5311, 10-bit DAC6311, and

12-bit DAC7311 (DACx311) are low-power, single-channel, voltage output

digital-to-analog converters (DACs). The low power consumption in normal operation

(0.55 mW at 5 V, reducing to 2.5 µW in power-down mode) makes the DACx311 an

excellent choice for portable, battery-operated applications.

These devices are monotonic by design,

provide excellent linearity, and minimize undesired code-to-code transient voltages

while offering an easy upgrade path within a pin-compatible family. All devices use

a versatile, three-wire serial interface that operates at clock rates of up to 50

MHz, and is compatible with standard SPI, QSPI, Microwire, and digital signal

processor (DSP) interfaces.

All devices use an external power

supply as a reference voltage to set the output range. The devices incorporate a

power-on reset (POR) circuit that powers up the DAC output at 0 V and remains at 0 V

until a valid write to the device occurs. The DACx311 contain a power-down feature,

accessed over the serial interface, that reduces current consumption of the device

to 0.1 µA at 2.0 V in power-down mode.

These devices are pin-compatible with

the DAC8311 and DAC8411, offering an easy upgrade path

from 8‑bit, 10‑bit, and 12‑bit resolution to 14‑bit and 16‑bit. All devices are

available in a small, 6‑pin, SC70 (SOT) package. This package offers a flexible,

pin- and function-compatible, drop-in DAC within the family over an extended

temperature range of –40°C to +125°C.
