Spi Current Sensor

Eric106 about 7 years ago 4 sure i agree it definitely can be done with a microcontroller s on board adc and i suppose all that bad is subjective.

Spi current sensor.

The coreless concept significantly reduces footprint compared with existing solutions. Texas instruments have today announced the release of the industry rsquo s first digital current sensor and voltage monitor with simultaneous sampling and spi interface. Current sensor and voltage monitor with spi 1 features 3 description the lmp92064 is a precision low side digital current 1 two simultaneous sampling 12 bit adcs sensor and voltage monitor with a digital spi conversion rate. Tli4970 is a high precision current sensor based on infineon s proven hall technology.

Tli4970 is an easy to use fully digital solution that does not require external calibration or additional parts such as a d converters 0 pamps or reference voltage. That being said if there is enough interest for an i2c current sensor please let us know. It would be something worth considering. This analog frontend afe includes a precision current sense amplifier to measure a load current across a shunt resistor and a buffered voltage channel to measure the voltage supply of the load.

Integrating a precision current sense amplifier and two 12 bit analog to digital converter channels that simultaneously capture voltage and current data the lmp92064 features an spi interface which transfers real time data at. But to do it right requires a properly designed anti. This analog frontend afe includes a. 125 ksps minimum interface.
