DAC101S101
10 位微功耗、RRO 数模转换器
The is a full-featured, general purpose 10-bit voltage-output digital-to-analog converter DAC that can operate from a single +2.7 V to 5.5 V supply and consumes just 175 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 2.7 V to 3.6 V range.
The supply voltage for the DAC101S101 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 DAC101S101 make it an excellent choice for use in battery operated equipment.
The DAC101S101 is a direct replacement for the AD5310 and is one of a family of pin compatible DACs, including the 8-bit DAC081S101 and the 12-bit DAC121S101. The DAC101S101 operates over the extended industrial temperature range of −40°C to +105°C while the DAC101S101Q operates over the Grade 1 automotive temperature range of −40°C to +125°C. The DAC101S101 is available in a 6-lead SOT and an 8-lead VSSOP and the DAC101S101Q is availabe in the 6-lead SOT only.
