1 / 83 page  DACx3202 12-Bit and 10-Bit, Dual, Voltage and Current Output Smart DACs With Auto-Detected I2C, PMBus™, or SPI Interface 1 Features • Programmable voltage or current outputs with flexible configuration: – Voltage outputs: • 1 LSB INL and DNL (10-bit and 8-bit) • Gains of 1x, 1.5x, 2x, 3x, and 4x – Current outputs: • 1 LSB INL and DNL (8-bit) • ±25 μA, ±50 μA, ±125 μA, ±250 μA output range options • Programmable comparator mode for all channels • High-impedance output when VDD is off • High-impedance and resistive pulldown power- down modes • 50-MHz SPI-compatible interface • Automatically detected I2C, PMBus™, or SPI interface – 1.62-V VIH with VDD = 5.5 V • General-purpose input/output (GPIO) configurable as multiple functions • Predefined waveform generation: sine, cosine, triangular, sawtooth • User-programmable nonvolatile memory (NVM) • Internal, external, or power-supply as reference • Wide operating range: – Power supply: 1.8 V to 5.5 V – Temperature: –40˚C to +125˚C • Tiny package: 16-pin WQFN (3 mm × 3 mm) 2 Applications • Rack server • Optical module • Inter-DC interconnect (metro) • High performance computing • Standard notebook PC 3 Description The 12-bit DAC63202 and 10-bit DAC53202 (DACx3202) are a pin-compatible family of dual- channel, buffered, voltage-output and current-output smart digital-to-analog converters (DACs). The DACx3202 devices support Hi-Z power-down mode and Hi-Z output during power-off conditions. The DAC outputs provide a force-sense option for use as a programmable comparator and current sink. The multifunction GPIO, function generation, and NVM enable these smart DACs for processor- less applications and design reuse. These devices automatically detect I2C, PMBus, and SPI interfaces and contain an internal reference. The feature set combined with the tiny package and low power make these smart DACs an excellent choice for applications such as voltage margining and scaling, dc set-point for biasing and calibration, and waveform generation.
