TLV5627 说明
The TLV5627 is a four channel, 8-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 TLV5627 is programmed with a 16-bit serial word comprised of a DAC address, individual DAC control bits, and an 8-bit DAC value.
The device has provision for two supplies: one digital supply for the serial interface (via pins DVDD and DGND), and one for the DACs, reference buffers and output buffers (via pins AVDD and AGND). Each supply is independent of the other, and can be any value between 2.7 V and 5.5 V. The dual supplies allow a typical application where the DAC will be controlled via a microprocessor operating on a 3-V supply (also used on pins DVDD and DGND), with the DACs operating on a 5-V supply.
