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.
