7-V to 5.
5-V supply and consumes just 177 µA of current at 3.
6 V.
The on-chip output amplifier allows rail-torail 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 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 consum...
