具有差分ADC的最小PIC是多少

我正在寻找哪一个是最小的PIC完成:-ADC与差分输入-少量引脚,SOIC8或SMD更小的包将是确定的-一个I2C接口-电源3.3V CAPABLE在芯片的参数搜索,没有办法指定差分ADC,我没有找到任何官方在我的手动搜索中,我找到了28针的16F1782.好像是最小的一个。但我想确定一下。谢谢!

    I am searching which is the smallest PIC that accomplishes:
- ADC with differential input
- few pins, SOIC8 or SMD smaller package would be OK
- An I2C interface
- Power 3.3V capable
In the microchip's site parametric search there is no way to specify differential ADC, and I have not found any official parts list.
In my manual search I have found the 16F1782 that has 28 pin. It seems it is the smallest one. But would like to be sure.
Thanks!

UQFN-28中的1782为4x4mm。如果你能处理0.4毫米音高,没有比这更小的图片了。它是少数几个具有12bit ADC的小部件之一,但您没有指定是否需要12位。

    The 1782 in UQFN-28 is 4x4mm. There aren't many PICs smaller than that, if you can handle 0.4mm pitch. It's one of the few smaller parts with a 12bit ADC, also, but you didn't specify if you need 12bits.

谢谢!有较小引脚数的选项吗?对于我的应用,14针装置就足够了。

    Thanks! Any option with smaller pin count? For my application 14 pin device would be enough.

尝试使用单片机产品选择器为自己。苏珊

部分选择器在微分对SE ADC上是无声的。但似乎只有16F17XX部分在28引脚或更大的差异的ADC。

    Part selector is silent on diff vs se adc. But it seems that only 16f17xx parts in 28 pin or greater have diff adc.
