General Description

The G767 is a precise digital thermometer that reports

the temperature of both a remote sensor and its own

package. The remote sensor is a diode-connected

transistor typically a low-cost, easily mounted 2N3904

NPN type-that replace conventional thermistors or

thermocouples. Remote accuracy is 鹵3擄C for multiple

transistor manufacturers, with no calibration needed.

The remote channel can also measure the die tem-

perature of other ICs, such as microprocessors, 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擄C, in two鈥檚-complement format.

Measurements can be done automatically and

autonomously, 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 supply-current drain.

The G767 is available in a small, 16-pin SSOP sur-

face-mount package.
