These devices include a 2.5-V, 4-ppm/℃ internal reference, giving a full-scale output voltage range of 2.5 V or 5 V. The internal reference has an initial accuracy of ±5 mV and can source or sink up to 20 mA at the VREFIN/VREFOUT pin.These devices are monotonic, providing excellent linearity and minimizing undesired code-to-code transient voltages (glitch). They use a versatile three-wire serial interface that operates at clock rates up to 50 MHz. The interface is compatible with standard SPI, QSPI, Microwire, and digital signal processor (DSP) interfaces.DAC856x 主要特性:Relative Accuracy: DAC856x (16-Bit): 4 LSB INL DAC816x (14-Bit): 1 LSB INL DAC756x (12-Bit): 0.3 LSB INLGlitch Energy: 0.1 nV-s Bidirectional Reference: Input or 2.5-V Output Output Disabled by Default ±5-mV Initial Accuracy (Max) 4-ppm/℃ Temperature Drift (Typ) 10-ppm/℃ Temperature Drift (Max) ---------------------------------------------------------精品 文档---------------------------------------------------------------------下载后可任意编辑20-mA Sink/Source CapabilityPower-On Reset to Zero Scale or Mid-Scale Low-Power: 4 mW (Typ, 5-V AVDD, Including Internal Reference Current) Wide Power-Supply Ran...
