TLV5616

TLV5616与TLC5615有什么不同?用MSP430F149可以驱动TLC5615的程序却驱动不起来TLV5616什么原因?

可以在TI网站上搜索这两颗料，然后进行比较.

The TLV5616 is a 12-bit voltage output digital-to-analog converter (DAC) with a flexible 4-wire serial interface. The 4-wire serial interface allows glueless interface to TMS320, SPI, QSPI, and Microwire serial ports. The TLV5616 is programmed with a 16-bit serial string containing 4 control and 12 data bits. Developed for a wide range of supply voltages, the TLV5616 can operate from 2.7 V to 5.5 V.

The TLC5615 is a 10-bit voltage output digital-to-analog converter (DAC) with a buffered reference input (high impedance). The DAC has an output voltage range that is two times the reference voltage, and the DAC is monotonic. The device is simple to use, running from a single supply of 5V. A power-on-reset function is incorporated to ensure repeatable start-up conditions.

Hi lu su,

下面这张图是TLV5616与TLC5615的串行数据格式，可以看出虽然都是SPI接口，但是数据包格式是有差别，所以驱动程序需要根据芯片的datasheet调整
