The chip of car plan step with holy small country

Holy state microelectronics has rolled out catenary of a few signal and chip of step of plan of car of power source management in succession, evaluate level in test and verify at present or already entered sale phase.

For example holy country is small one when roll out exceeds small size, low power comsumption, 16, take the ADC with internal fiducial tension: SGM58031Q, . Can apply in car application process, portable equipment, flow control, batteries to monitor system and temperature to measure wait for a domain.

SGM58031Q isInside buy is fiducial of voltage source exceed small-sized low power comsumption 16 modulus converter, supportable 3V works to 5.5V voltage. SGM58031Q interior includes piece on reference and oscillator. Parts of an apparatus supports I2C compatible port, can choose 4 I2C from the address. The data rate of SGM58031Q filter is top can amount to 960SPS. Parts of an apparatus is had piece on PGA, can offer low the input voltage limits to ± 256mV. SGM58031Q is inputted answer with implement support 4 Chan Duan are inputted or 2 poor cent input configuration.

This SGM58031Q has agile input multichannel answer is used implement. It is OK configuration differs minute of input for 2 or 4 Chan Duan are inputted.

No matter input configuration to divide input or Chan Duan to input for difference, any inputs bring the absolutely voltage on the foot to must arrive in GND inside the limits of Vpage

Imitate input

This SGM58031Q has capacitance of a switch to input class. The existence when ADC works fills discharge electric current. Equivalent input impedance can estimate with REFF=Vin/Average.

Graph 6 medium difference input impedance to be Z6rF. Express the 1 difference that showed a pattern to divide input impedance.
