DAC6311 采用 SC70 的低功率单通道 1.8V 至 5.5V、80mA、8 位、10 位和 12 位 DAC
DAC6311 说明
The DAC5311 (8-bit), DAC6311 (10-bit), and DAC7311 (12-bit) are low-power, single-channel, voltage output digital-to-analog converters (DAC). They are monotonic by design and provide excellent linearity and minimize undesired code-to-code transient voltages while offering an easy upgrade path within a pin-compatible family. All devices use a versatile, 3-wire serial interface that operates at clock rates of up to 50MHz and is compatible with standard SPI™, QSPI™, MICROWIRE™, and digital signal processor (DSP) interfaces.
All devices use an external power supply as a reference voltage to set the output range. The devices incorporate a power-on reset (POR) circuit that ensures the DAC output powers up at 0V and remains there until a valid write to the device occurs.
