TA is the ambient temperature of the TMP43x. TDIODE is the temperature at the remote diode sensor. (2) Beta correction configuration set to 1000 and sensor is GND collector-connected (PNP collector to ground). (3) Beta correction configuration set to 0111 or sensor is diode-connected (base shorted to collector). (4) If beta correction is disabled (0111), then up to 1-k Ω of series line resistance is cancelled; if beta correction is enabled (1xxx), up to 300 Ω is cancelled. 6 Submit Documentation Feedback Copyright © 2009–2015, Texas Instruments Incorporated Product Folder Links: TMP431 TMP432 |
