G767

Remote/Local Temperature Sensor with SMBus

Serial Interface

Features

General Description

Two Channels: Measures Both Remote and

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 ±3°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.

Local Temperatures

No Calibration Required

SMBus 2-Wire Serial Interface

Programmable Under/Overtemperature Alarms

Supports SMBus Alert Response

Accuracy:

±2°C (+60°C to + 100°C, local)

±3°C (-40°C to +125°C, local)

±3°C (+60°C to +100°C, remote)

3µA (typ) Standby Supply Current

70µA (max) Supply Current in Auto- Convert

Mode

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 two’s-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.
