1 / 59 page  DACx3701 10-Bit and 8-Bit, Voltage-Output Smart DACs With Nonvolatile Memory and PMBus™ Compatible I2C Interface With GPI Control 1 Features • 1 LSB INL and DNL (10-bit and 8-bit) • Wide operating range – Power supply: 1.8 V to 5.5 V – Temperature range: –40°C to +125°C • General-purpose input (GPI) based function trigger • PMBus™ compatible I2C interface – Standard, fast, and fast mode plus – Four device address options configured using the broadcast address – 1.62-V VIH with VDD = 5.5 V • User-programmable nonvolatile memory (NVM/ EEPROM) – Save and recall all register settings • Programmable waveform generation: Square, triangular, and sawtooth • Pulse-width modulation (PWM) output using triangular waveform and FB pin • Preprogrammed medical-alarm tone-generation mode: low-, medium-, and high-priority alarms • Digital slew rate control • Internal reference • Very low power: 0.2 mA at 1.8 V • Flexible start-up: High impedance or 10K-GND • Tiny package: 8-pin WSON (2 mm × 2 mm) 2 Applications • Oven • Ventilators • Infusion pump • Anesthesia delivery systems • Surgical equipment • Rack server • Exit and emergency lighting 3 Description The 10-bit DAC53701 and 8-bit DAC43701 (DACx3701) are a pin-compatible family of buffered voltage-output smart digital-to-analog converters (DACs). These devices consume very low power, and are available in a tiny 8-pin WSON package. The feature set combined with the tiny package and low power make the DACx3701 an excellent choice for applications such as appliance door fade-in fade-out, processorless LED dimming with PWM input, general- purpose bias point generation, voltage margining and scaling, PWM signal generation, and medical alarm tone generation. These devices have nonvolatile memory (NVM), an internal reference, a PMBus-compatible I2C interface, and a general-purpose input. The DACx3701 operates with either an internal reference or with the power supply as a reference, and provides a full-scale output of 1.8 V to 5.5 V. The DACx3701 are smart DAC devices because of their advanced integrated features. With force-sense output, GPI based function trigger, medical alarm, PWM output, and NVM capabilities, smart DACs enable system performance and control without the use of software.
