General Description

The DAC121S101 is a full-featured, general purpose 12-bit voltage-output digital-to-analog converter (DAC) that can operate from a single +2.7V to 5.5V supply and consumes just 177 µA of current at 3.6 Volts. The on-chip output amplifier allows rail-to-rail output swing and the three wire serial interface operates at clock rates up to 30 MHz over the specified supply voltage range and is compatible with standard SPI, QSPI, MICROWIRE and DSP interfaces. Competitive devices are limited to 20 MHz clock rates at supply voltages in the 2.7V to 3.6V range.

The supply voltage for the DAC121S101 serves as its voltage reference, providing the widest possible output dynamic range. A power-on reset circuit ensures that the DAC output powers up to zero volts and remains there until there is a valid write to the device. A power-down feature reduces power consumption to less than a microWatt.

The low power consumption and small packages of the DAC121S101 make it an excellent choice for use in battery operated equipment.

The DAC121S101 is a direct replacement for the AD5320 and the DAC7512 and is one of a family of pin compatible DACs, including the 8-bit DAC081S101 and the 10-bit DAC101S101. The DAC121S101 operates over the extended industrial temperature range of −40°C to +105°C while the DAC121S101Q operates over the Grade 1 automotive temperature range of −40°C to +125°C. The DAC121S101 is available in a 6-lead TSOT and an 8-lead MSOP and the DAC121S101Q is available in the 6-lead TSOT only.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
