AD57901
1是一款单通道、20位、无缓冲电压输出DAC，采用最高33 V的双极性电源供电。正基准电压输入范围为5 V至VDD – 2.5V，负基准电压输入范围为VSS + 2.5 V至0V。相对精度最大值为±2 LSB，保证工作单调性，微分非线性(DNL)最大值为-1 LSB至+3 LSB。
The device features a versatile three-wire serial interface that is capable of operating at clock rates up to 50 MHz and is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interfaces. An in-chip reference buffer is provided. It has a built-in power-on reset circuit that ensures that the DAC is powered up to 0 V and maintains a known output impedance until a valid write operation is performed on the device. Disable the feature puts the output in a defined load state.
