Although AVSS and VSS are completely isolated internally in the LC82151, AVDD and VDD are connected through the substrate. This means that there must be no potential difference between AVDD and VDD. Also, the power supply voltage rise and fall times must be under 3 ms. Parameter Symbol Conditions Ratings Unit min typ max Resolution 6 bit Reference resistors value DAREFL, DAREFH 5.0 kΩ Analog Characteristic D/A Converter Parameter Symbol Conditions Ratings Unit min typ max Resolution 8 bit Linearity error ±1 LSB Differential linearity error ±1 LSB A/D Converter at an ATAP potential of 4.2 V A/D Converter |
