3 Description

The DAC8311 (14-bit) and DAC8411 (16-bit) devices are low-power, single-channel, voltage output digital-to-analog converters (DAC). They 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, 3-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 ensures the DAC output powers up at 0 V and remains there until a valid write to the device occurs. The DAC8311 and DAC8411 contain a power-down feature, accessed over the serial interface, that reduces current consumption of the device to 0.1 μA at 2 V in power down mode. The low power consumption of these devices in normal operation makes it ideally suited for portable, battery-operated equipment. The power consumption is 0.55 mW at 5 V, reducing to 2.5 μW in power-down mode.

These devices are pin-compatible with the DAC5311, DAC6311, and DAC7311, offering an easy upgrade path from 8-, 10-, and 12-bit resolution to 14- and 16-bit. All devices are available in a small, 6-pin, SC70 package. This package offers a flexible, pin-compatible, and functionally-compatible drop-in solution within the family over an extended temperature range of –40°C to 125°C.
