Precision Resistors Questions
What kinds of circuits need precise resistors and how is their precision guaranteed?
Precision resistors are used in measurement , callibration ,and other precise and critical instruments .
A resistor has a tolerance around marked quantity , which must be concidered to be better than errors respected in the system .
But an other important aspect is that the precision resistor is also more stable in environmental changes , like temperature and humidity .
The precision is guaranteed by material , construction and technology involved .
1- carbon resistors & polymer resistors 5%
2- metal film 1%
3-metal film & wire wound 0.1%
4-wire wound beter than 0.1%
new high-precision data acquisition front-end battery management IC
Austriamicrosystems launches high-precision data acquisition before the end of IC AS8510, to meet the current battery of the car, voltage and temperature measurement applications, and the need for accurate measurement of small signal interface applications General sensor.
The new flexible sensor interface IC solutions that have many other benefits, such as for the first time offset and noise is less than 1 LSB in 16-bit dual channel ADC + PGA architecture. Hp laptop battery AS8510 is highly configurable, the system can be adjusted to meet different system needs to adapt to current and future demand for different types of battery management. Austriamicrosystems AS8510 for use with the system “based on a chip” and a microcontroller can lower the price of U.S. $ 2.8 to provide a full game of high or low side of the sensor battery solutions semiconductors.
AS8510 data acquisition before the end of IC includes two separate 16-bit ADC analog input channels, each channel has independent programmable sampling rate. To deal with + / – 160 mV signal, each channel has a low drift programmable gain amplifier, PGA or bypass it to process the signal from 0V to 1V. Therefore, the battery in mA confers kA current variation of 100 μΩ sense resistance to complement measures. AS8510 linear structure of high and wide frequency Σ-Δ sample of electric vehicle (EV) application provides flexible support. The imbalance of the auto-zero (both channels are available) to enable low resistance sense resistor (as low as 100 μΩ) carrying out high precision measurements, the introduction of the loss is negligible. (compaq r3000 battery), HP Presario X6000 Battery, HP Pavilion ZV5000 BatteryIn addition, AS8510 includes a variety of operating modes, such as low power standby mode, the function of the ongoing monitoring can be achieved independently of wake.
Austriamicrosystems sensor interfaces for automotive and SBC ASSP Manfred Brandl, product manager, said: “battery-powered devices and high-speed market growth on a vehicle’s electrical power management more accurate and effective demand is increasing. AS8510 offers designers a wide range of applications required for precision and flexibility. In addition, austriamicrosystems AS8510 with an auxiliary microcontroller IC LIN and low cost, shorten time to market for automotive applications, (HP Pavilion ZV5000 Battery)for rapid market development of the most competitive prices and better performance. “
AS8510 12V and current shunt sensor system when used in combination, can connect the ground terminal of the battery can also use the dedicated level converter IC and connecting the positive supply terminal, the device can also be used as an accurate measurement of small signals common sensor interface. AS8510 fully differential input to capture potential 300mV above ground and below ground potential 160mV differential common mode signal. The dual-channel architecture can be achieved “Σ-Δ” frequency and other technical correction of numerical error or the use of an external microcontroller to capture the bridge to monitor the correction of current and voltage . In addition, AS8510 standby mode consumes only 40 microA current.
AS8510 high-precision instrument data acquisition can be configured as a differential dual-channel synchronous operation, or multiplexed into two asymmetric channels and a channel for a differential measurement control. In addition to measuring current and over voltage, AS8510 can also be due to a sensor chip or internal 250μA current source powered outdoor temperature sensor for accurate measurement of temperature. AS8510 includes an internal reference source of high precision, integrated low-pass digital filter, the oscillator on-chip precision son and 4-SPI interface.
AS8510 uses SSOP20 package, (HP Presario X6000 Battery,)operating voltage is 3.3 V, the working environment temperature of -40 to 125 ° C
Using knowledge of the impedance of the battery, to achieve accurate load and temperature compensation. The most important is that the parameters of the battery through dynamic learning, that the measures in the life of the battery can be measured with precision over power. Coulomb counting method used alone, or the battery voltage is compared with the applicable law, impedance technologically to the extent of remaining battery capacity has become more outstanding.
He is running the process, the need to continue to maintain the impedance of the battery (Rbat) and depth of discharge (DOD) and the relationship between the temperature of the function of maintaining database form. Understanding what happened in different operating to help determine when to update or to use these forms. Meter, the non-volatile memory that there are many definitions of charge, (compaq r3000 battery), HP Presario X6000 Battery, HP Pavilion ZV5000 Battery discharge, after releasing the load, discharge and other state after the relaxation of current threshold. After the charge or stop the flow stopped, the relaxation time “for stabilizing the voltage of the battery.
