Note1:
Guaranteed but not 100% tested.
Note2:
Quantization error is not included in specifications for temperature accuracy. For example, if the G767 de-
vice temperature is exactly +66.7°C, or +68°C (due to the quantization error plus the +1/2°C offset used
for rounding up) and still be within the guaranteed ±1°C error limits for the +60°C to 100°C temperature
range. See Table2.
Note3:
A remote diode is any diode-connected transistor from Table1. T
R
is the junction temperature of the re-
mote of the remote diode. See Remote Diode Selection for remote diode forward voltage requirements.
Note4:
The SMBus logic block is a static design that works with clock frequencies down to DC. While slow operation is
possible, it violates the 10kHz minimum clock frequency and SMBus specifications, and may monopolize the bus.
Note5:
Note that a transition must internally provide at least a hold time in order to bridge the undefined region
(300ns max) of SMBCLK’s falling edge.
Note6:
Specifications from -55°C to +125°C are guaranteed by design, not production tested.
