MX844中文资料艾赛斯数据手册PDF规格书

Description:

The MX844 is a fully integrated subsystem that measures temperature plus differential current and voltage. An internal temperature sensor measures ambient temperature with 2.5°C accuracy. Current and voltage measurements are made differentially through a four input multiplexer connected to a programmable gain fully differential sense amplifier.

Features:

• Wide Input Supply Range: 4.5V to 40V

• Programmable gain differential amplifier (±10mV, ±25mV, ±50mV, ±250mV ranges)

• 4 channel differential input multiplexer (3 input channels plus ground)

• Integrated 12-bit ADC

• Serial data output (SDO) with data ready pin

• Fine calibration of Full Scale Range (FSR) using VTRIM pin

• Bi-directional Current Sense

• Internal temperature sensor with 0.2°C resolution

• Compatible with 3.3V and 5V Microcontrollers

• Operating Temperature Range: -40°C to 85°C

• 5mm x 5mm, QFN-28 RoHS Package
