TEXAS INSTRUMENTS TLC5628CDWG4 数模转换器, 八路, 8 bit, 45 kSPS, 串行, 4.75V 至 5.25V, SOIC, 16 引脚
The is an octal 8-bit voltage output Digital-to-analog Converter DAC with buffered reference inputs high impedance. The DAC produces an output voltage that ranges between either one or two times the reference voltages and GND and are 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. Digital control of the TLC5628C is over a simple three-wire serial bus that is CMOS compatible and easily interfaced to all popular microprocessor and microcontroller devices. The 12-bit command word comprises 8-bit of data, three DAC select bits and a range bit, the latter allowing selection between the times 1 or times 2 output range. The DAC registers are double buffered, allowing a complete set of new values to be written to the device and then all DAC outputs are updated simultaneously through control of LDAC. The digital inputs feature Schmitt triggers for high-noise immunity.
