Описание
The DAC7678SPW is a low-power voltage-output 8-channel 12-bit Digital-to-analog Converter (DAC) includes a 2.5V internal reference, giving a full-scale output voltage range of 5V. The internal reference has an initial accuracy of ±5mV and can source up to 20mA at the VREFIN/VREFOUT pin. The device is monotonic, provides very good linearity and minimizes undesired code-to-code transient voltages (glitch). The DAC7678 uses a versatile, 2-wire serial interface that is I²C-compatible and operates at clock rates of up to 3.4MHz. The DAC7678 incorporates a power-on-reset circuit that ensures the DAC output powers up to either zero-scale or mid-scale until a valid code is written to the device. This device contains a power-down feature, accessed over the serial interface that reduces the current consumption of the device to typically 0.42µA at 5V. Power consumption is typically 3.56mW at 3V, reducing to 0.68µW in power-down mode.
• Relative accuracy- 1 LSB INL
• Glitch energy - 0.15nV-s
• Power-on reset to zero scale or midscale
• Ultralow power operation - 0.13mA/channel at 5V
• 2-wire serial interface
• On-chip output buffer amplifier with rail-to-rail operation
• Green product and no Sb/Br
