CT7468 Unfold All
Product Description
CT7468 is a 9-channel (8-channel Remote and 1-channel Local) Temperature Sensor with Remote measurement range up to -200℃~200℃ and SMBus Digital Interface. It is ideally used in Temperature Sensing and Monitoring Systems, such as Cold-chain, BBQ oven and Liquid nitrogen etc.
Product Features

l  Operation Voltage: 1.75V to 5.5V

l  Average Operating Current: 45uA (Typ.)for all channels one time measurement at VCC = 3.3V

l  Standby Current: 3.0uA (Typ.)

l  Temperature Accuracy without calibration for all channels:±1oC from 0oC to 50oC

l  13 bit ADC for 0.0625oC resolution

l  Digital interface compatible with SMBus and I2C

l  Series Resistance Cancellation, n-Factor correction, Offset correction and Diode fault detection for each remote channel.

l  Individually programmable THERM limit temperature for any of 9 channels with share Hysterisis data

l  Register lock feature to protect register data

l  8 slave addresses available by setting AD0 pin

l  Temperature Range:

-40oC to 125oC for local channel

-200oC to 200oC for remote channels

l  The measurement range can be extended from -200 oC to 200 oC for remote channels with 9018 transistor.
