General Description
The G766 is a precise digital thermometer that reports
the temperature of a remote sensor. The remote sen-
sor is a diode-connected transistor typically a low-cost,
easily mounted 2N3904 NPN type-that replace con-
ventional thermistors or thermocouples. Remote ac-
curacy is ±3°C for multiple transistor manufacturers,
with no calibration needed. The G766 can also meas-
ure the die temperature of other ICs, such as micro-
processors, that contain an on-chip, diode-connected
transistor.
The 2-wire serial interface accepts standard System
Management Bus (SMBus
TM
) Write Byte, Read Byte,
Send Byte, and Receive Byte commands to program
the alarm thresholds and to read temperature data.
The data format is 7 bits plus sign, with each bit cor-
responding to 1°C, in twos-complement format. Meas-
urements can be done automatically and autono-
mously, with the conversion rate programmed by the
user or programmed to operate in a single-shot mode.
The adjustable rate allows the user to control the sup-
ply-current drain.
The G766 is available in a small, 10-pin MSOP sur-
face-mount package.
