... SMBT3904 Zetex (England) FMMT3904CT-ND Note: Discrete transistors must be diode connected (base shorted to collector). The 7-bit slave address of the MAX6636UP9A+ is 1001 101 (binary). Follow these guidelines to reduce the measurement error when measuring remote temperature: 1) Place the MAX6636 as close as is practical to the remote diode. In noisy environments, such as a computer motherboard, this distance can be 4in to 8in (typ) ...
