These devices include a 2.5-V, – DAC756x (12-Bit): 0.3 LSB INL 4-ppm/ °C internal reference, giving a full-scale output voltage range of 2.5 V or 5 V. The internal reference • Glitch Energy: 0.1 nV-s has an initial accuracy of ±5 mV and can source or • Bidirectional Reference: Input or 2.5-V Output sink up to 20 mA at the VREFIN/VREFOUT pin. – Output Disabled by Default These devices are monotonic, providing excellent – ±5-mV Initial Accuracy (Max) linearity and minimizing undesired code-to-code – 4-ppm/°C Temperature Drift (Typ) transient voltages (glitch). They use a versatile – 10-ppm/°C Temperature Drift (Max) three-wire serial interface that operates at clock rates – 20-mA Sink/Source Capability up to 50 MHz. The interface is compatible with standard SPI ™, QSPI™, Microwire™, and digital • Power-On Reset to Zero Scale or Mid-Scale signal processor (DSP) interfaces. The DACxx62 • Low-Power: 4 mW (Typ, 5-V AVDD, Including devices incorporate a power-on-reset circuit that Internal Reference Current) ensures the DAC output powers up at zero scale until • Wide Power-Supply Range: 2.7 V to 5.5 V a valid code is written to the device, whereas the • 50-MHz SPI With Schmitt-Triggered Inputs DACxx63s similarly power up at mid-scale. These • LDAC and CLR Functions devices contain a power-down feature that reduces current consumption to typically 10 nA at 5 V. The • Output Buffer With Rail-to-Rail Operation low power consumption, internal reference, and small • Packages: QFN-10 (3x3 mm), MSOP-10 footprint make these devices ideal for portable, • Temperature Range: –40°C to 125°C battery-operated equipment. The DACxx62 devices are drop-in and APPLICATIONS function-compatible with each other, as are the • Portable Instrumentation DACxx63s. The entire family is available in MSOP-10 • Bipolar Outputs (reference design) and QFN-10 packages. • PLC Analog Output Module (reference design) Table 1.
