产品概述 返回TOPRsA嘉泰姆
The CXHA3183 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 ±1°C with no calibration
needed. It also has a build-in noise filtering function in
remote sensor measuring the diode temperature. The
remote channel can also measure the die temperature
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) Write Byte, Read Byte,
Send Byte, and Receive Byte commands to program
the alarm thresholds and to read temperature data.
The data format is 11bits plus sign, with each bit corresponding
to 0.125°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.
The CXHA3183 and CXHA3183-1 have the same functions but
different SMBus slave addresses. This allows for one
of each to be on the bus at the same time.
The CXHA3183 is available in a small, 8-pin SOP and
MSOP surface-mount package.
