  • Precision RTD Instrumentation for Temperature Sensing
    ) tionally, RTDs are biased with a constant current source. The voltage drop across the RTD is condi- tioned using an Instrumentation Amplifier which For instance, a 2V ADC reference voltage (V ) REF requires multiple resistors, capacitors and few opera- results in a 1 µV/LSb (Least Significant Bit
  • Op Amp Precision Design: DC Errors
    circuitry is not shown). All error sources are Description ) is infinite. The ignored and the open-loop gain (A OL This application note covers the essential background output voltage is related to the input voltages as shown information and design theory needed to design a in Equation 1. precision
  • Using a Digital Potentiometer to Optimize a Precision Single Supply Photo Detect
    electrical voltage. In these circuits, photodiodes are used to capture the light energy and transform it to a small current. This current is proportional to the level of illumination from the light source. A preamplifier then converts the current (in amperes) from the photodiode sensor into a usable
  • AN801 DSCA Calibration Procedure
    Using the module data sheet or module top label, determine the input and output ranges of the module. Connect a precision voltage source, current source, frequency source, RTD simulator, resistance or thermocouple simulator as appropriate to the input of the module. Set the input source
  • Need a Go-To Solution for Making Strain Gauge Measurements Easier?
    For many structural engineers, the VTI Instruments EX1403 Precision Bridge and Strain Gauge Instrument from AMETEK Programmable Power is the go-to solution for complex test applications. One reason why is that it's very easy to programmatically configure the built-in strain gauge excitation sources
  • Measurement of Electronic Component Impedance Using a Vector Network Analyzer
    impedance. Such methods are based on the use of bridges (with or without auto-balancing), resonators, precision current and voltage meters, and network analyzers. The vector network analyzer (VNA) has recently become a powerful tool for analyzing impedance in a broad band, which partially covers the GHz
  • How to Control the Interference of Transformer to Amplifier?
    The transformer can interfere with the amplifier through magnetic field, electromagnetic induction and circuit. It is the biggest interference source in the audio machine. Therefore, to deal with its working state and application environment, the interference generated by the power transformer can
  • 5 Tests to Calibrate Your DT80 Range Data Logger
    with using the dataTaker command language and a suitable terminal application such as DeTransfer. Equipment required: 1x Programmable Precision voltage source*. 1x 100O 0.05% 5ppm or better. 1x 1000O 0.05% 5ppm or better. *The high-voltage range of the logger has an input impedance of approximately
