The Device Type Register is an OTP configuration register which contains device configuration information. Bit 5 - Bit 0 are
The Low Pass Filter selection bit selects between one of three low pass filter options. These bits can be factory or user pro-
The Range Selection Bits indicate the full scale range of the device, as shown below. These bits are factory programmed.
Table 3. Factory Configuration Register
This filter option is not implemented. LPF[1:0] must not be set to this value to guarantee proper operation and performance.
