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.
