Multichannel Remote/Local Temperature Sensors 4 _______________________________________________________________________________________ ELECTRICAL CHARACTERISTICS (continued) (VCC = +5V, STBY = VCC, configuration byte = X0XXXX00, TA = -55°C to +125°C, unless otherwise noted.) (Note 6) Note 1: Guaranteed by design, but not production tested. Note 2: Quantization error is not included in specifications for temperature accuracy. For example, if the MAX1668/MAX1805/ MAX1989 device temperature is exactly +66.7°C, the ADC may report +66°C, +67°C, or +68°C (due to the quantization error plus the +0.5°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 Table 2. Note 3: A remote diode is any diode-connected transistor from Table 1. TR is the junction temperature of the remote diode. See the Remote-Diode Selection section for remote-diode forward-voltage requirements. Note 4: 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 can monopolize the bus. Note 5: 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 tHD:DAT. Note 6: Specifications from -55°C to +125°C are guaranteed by design, not production tested.
