W83772G

1.

GENERAL DESCRIPTION

W83772G is a 2-channel temperature sensor with Simple Serial Transport (SST) interface. W83772G

has an on-chip thermal sensor and a remote temperature sensor. The remote temperature sensor

input could be connected to thermal diode or transistor such as 2N3904. A 10-bit ADC (Analog-to-

Digital Converter) is built inside W83772G to convert the monitored temperature value with 0.125

C

resolution.

W83772G is a high precision, low-power consumption IC supporting 1.5V SST interface. The package

type is 8-pin, MSOP (TSSOP), and the operating voltage is 3.3 V ±10%.
