Digital-to-analog converter employing a common trigger and reference signal |
摘要 |
The D/A converter comprises: a digital counter receiving a reference clock pluses and a reference voltage as a start signal so as to output a stop signal when the digital counter counts the reference clock pulses until a predetermined number; and a number is reached, and an RC circuit having a resister and a capacitor receiving the reference voltage so as to be charged by a predetermined time constant until the stop signal is inputted to the RC circuit, whereby the RC circuit is charged up to a voltage corresponding to a time distance between the start signal and the stop signal.
