ADS1146 DETAILED REGISTER DEFINITIONS (continued)
FSC[23:0]
These bits make up the full-scale calibration coefficient register.
FSC0—Full-Scale Calibration Coefficient Register 0
FSC0 - ADDRESS 07h RESET VALUE IS PGA DEPENDENT
(1)
BIT 7 BIT 6 BIT 5 BIT 4 BIT 3 BIT 2 BIT 1 BIT 0
FSC7 FSC6 FSC5 FSC4 FSC3 FSC2 FSC1 FSC0
(1) The reset value for FSC is factory-trimmed for each PGA setting. Note that the factory-trimmed FSC reset value is automatically loaded
whenever the PGA setting is changed.
FSC1—Full-Scale Calibration Coefficient Register 1
FSC1 - ADDRESS 08h RESET VALUE IS PGA DEPENDENT
(1)
BIT 7 BIT 6 BIT 5 BIT 4 BIT 3 BIT 2 BIT 1 BIT 0
FSC15 FSC14 FSC13 FSC12 FSC11 FSC10 FSC9 FSC8
(1) The reset value for FSC is factory-trimmed for each PGA setting. Note that the factory-trimmed FSC reset value is automatically loaded
whenever the PGA setting is changed.
FSC2—Full-Scale Calibration Coefficient Register 2
FSC2 - ADDRESS 09h RESET VALUE IS PGA DEPENDENT
(1)
BIT 7 BIT 6 BIT 5 BIT 4 BIT 3 BIT 2 BIT 1 BIT 0
FSC23 FSC22 FSC21 FSC20 FSC19 FSC18 FSC17 FSC16
(1) The reset value for FSC is factory-trimmed for each PGA setting. Note that the factory-trimmed FSC reset value is automatically loaded
whenever the PGA setting is changed.
ID—ID Register
IDAC0 - ADDRESS 0Ah RESET VALUE = x0h
BIT 7 BIT 6 BIT 5 BIT 4 BIT 3 BIT 2 BIT 1 BIT 0
ID3 ID2 ID1 ID0 DRDY MODE 0 0 0
Bits 7:4 ID3:0
Read-only, factory-programmed bits; used for revision identification.
Bit 3 DRDY MODE
This bit sets the DOUT/DRDY pin functionality. In either setting of the DRDY MODE bit, the DRDY
pin continues to indicate data ready, active low.
0 = DOUT/DRDY pin functions only as Data Out (default)
1 = DOUT/DRDY pin functions both as Data Out and Data Ready, active low
Bits 2:0 These bits must always be set to '000'.
