Description: TDC-GP22 为TDC-GP21的下一代升级产品.这颗芯片是与TDC-GP21芯片100 管脚和功能兼容的芯片,而且带有更
强大的功能. 尤其这颗芯片的最新第一波检测功能,将使TDC-GP22非常适合于高动态范围的超声波水表的应
用.可编程的比较器offset调整范围增加到了 ± 35 mV ,而且这个比较器offset将会在第一波检测后自动回
到0点比较.测量第一个回波脉冲的相对宽度将会给用户一个对于接收信号强度的提示.通过这个提示信息可以
用于系统的长期覆盖物的信号减弱判断,以及用于气泡检测.多个测量脉冲的数据处理和数据读出功能将会比
TDC-GP21更加简单方便.-The next generation TDC-GP22 TDC-GP21 upgrade products. This chip is pin and function compatible chip and the TDC-GP21 chip 100 tube, and with more
Powerful functions. This chip detection function especially the latest first, will make the TDC-GP22 ultrasonic water meter is very suitable for high dynamic range should be
. comparator offset programmable adjustment range increased to 35 mV, and the comparator offset will automatically back in the first wave detection
To 0 points of comparison. Measure the first echo pulse relative width will give the user a for received signal strength by the prompt information can prompt.
A signal for long term covering system weakened judgment, as well as for bubble detection. A plurality of pulse measurement data processing and data read function will be greater than
TDC-GP21 is more simple and convenient. Platform: |
