About output register and Rp_max of LDC1000 and LDC1051.

Other Parts Discussed in Thread: LDC1051

Please let me know two points below about output register and Rp_max of LDC1000 and LDC1051.

・Is a LDC output register a maximum of 8bits(255)?

 Although outputted only to 7bits(128), what is reasonable ?

・Rp_max is set as the maximum.

(Address 0x01 set 0x00:3926.991kΩ)

When LDC output becomes the same as Rp_max, is there any problem?

(Is a problem in the output of INTB?)

Best regards,

Satoshi

    LDC1000 registers are all 8bits wide, and can directly express values between 0 and 255. The LDC1000 output information spans several registers (for example, the L measurements span 3 registers - addresses 0x23, 0x24, and 0x25). You need to read the three registers and combine them together into a single 24 bit wide digital word to represent the output code.
