Texas Instruments DAC756x are low-power, voltage-output, dual-channel, 12-bit digital-to-analog converters (DACs). These devices include a 2.5 V, 4 ppm/°C internal reference, providing 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.
- Relative accuracy: 0.3 LSB INL
- Glitch energy: 0.1 nV s
- Bidirectional reference: Input or 2.5 V output
- Power-on reset to zero scale or mid-scale
- Low-power: 4 mW (Type, 5 VAVDD, including internal reference current)
