  • PGA900 DAC Output Stability Application Note
    PDF, 253 Kb, 档案已发布: Mar 4, 2015
    Capacitive load drive is one of the most common causes of operational amplifier stability issues. The load capacitance, CL, interacts with the open-loop output impedance of the amplifier, ZO, by adding a single or double pole in the open-loop response. The additional pole or poles degrades the circuit phase margin, resulting in transient overshoot and ringing, ac gain peaking
  • PGA900 as 4- to 20-mA Current Loop Transmitter
    PDF, 238 Kb, 档案已发布: May 7, 2015
    This application note shows the PGA900 used as a 2-wire, 4- to 20-mA current loop transmitter, a common method of transmitting sensor information in industrial process-monitoring applications. Transmitting sensor information (physical parameter measurements) through a current loop is particularly useful when the information must be sent to a remote location over long distances (1000 feet or more).

    PDF, 1.1 Mb, 档案已发布: May 8, 2015
    Understanding the input and output limitations of an instrumentation amplifier (IA) is important in interfacing a resistive bridge sensor to the PGA900. Adjusting the common mode voltage of the input signal appropriately allows us to maximize the gain. Maximizing the gain yields the largest output signal span for the 24-bit analog-to-digital converter (ADC). The largest signal span maximizes the c
