  • AFE882H1: AFE882H1, Chip select query

    Resolved
    Part Number: AFE882H1 Hi, For AFE882H1, when CS pin is pulled down, AFE chip do not respond. When used while SPI communication, AFE chip responds. What could be reason? Pull down value 10k resistor. Regards, Anurag

  • AFE882H1: Sleep mode current

    Resolved
    Part Number: AFE882H1 Hi, Datasheet mentioned: Low quiescent current: 180 µA (typical) With no communication, we get 300uA current. Can we put AFE chip to sleep through software. OR It(180uA/300uA) is what we can achieve lowest. /Anurag
