I've tried changing the values of the rc in case it was a input impedance issue. Assume I know nothing and you won't be far wrong, I think I was lucky with the 1827 comparator, I need ~65mv of hys. Thanks Geoff 2019-5-6 14:03:45 评论 举报 徐胤 提交评论 答案对人有帮...
在流量计产品中,某客户选用了Microchip公司的降压DC-DC转换器MCP16301T,不过因供货交期和价格压力,需求一款低成本、供货交期好的替代方案,本文重点推荐国产创瑞科技的降压型DC-DC转换器A7406AE6VR,可pin-to-pin替代MCP16301T,二者典型参数对比如下图1所示。 图1 A7406AE6VR与MCP16301T典型性能参数对比 从上图可...
circuit is not symmetric, the ADC input is single ended, and there is a minimum of filtering; the CMRR is good enough for moderate Common-mode noise. 4.3.11.2 Crosstalk DC crosstalk causes offsets that appear as a larger input offset voltage. Common causes include: • Common-mo...
From what we have discussed so far, the voltage across the current sense resistor has been assumed to be a fairly large signal within the measurement range of the ADC. But this is not commonly the case. As mentioned earlier, the current sense resistor dissipates IR power. Lowering the r...
