NADJUST= 1.008×2088

ηeff −2088

(3)

The η-factor correction value must be stored in 2's complement format, yielding an effective data range from

–128 to 127. The η-factor correction value is written to and read from pointer address 23h. The register power-on

reset value is 00h, thus having no effect unless a different value is written to the register. The resolution of the

η-factor register is 0.000483.

8.1.10 Remote Temperature Offset Register

The offset register allows the TMP9R01-SEP and TMP9R01-SP devices to store any system offset

compensation value that can result from precision calibration. The value in the register is stored in the

same format as the temperature result and is added to the remote temperature result upon every conversion.

Combined with the η-factor correction, this function allows for very accurate system calibration over the entire

temperature range.

8.1.11 Manufacturer Identification Register

The TMP9R01-SEP and TMP9R01-SP devices allow for the two-wire bus controller to query the device for

manufacturer and device IDs to enable software identification of the device at the particular two-wire bus

address. The manufacturer ID is obtained by reading from the pointer address FEh. The device reads 55h for the

manufacturer code.
