  • AD8235- 40 µA Micropower Instrumentation Amplifier in WLCSP Package
    AD8235: 40 µA Micropower Instrumentation Amplifier in WLCSP Package

    The AD8235 is the smallest and lowest power instrumentation amplifier in the industry. It is available in a 1.5 mm × 2.2 mm wafer level chip scale package (WLCSP). The AD8235 draws a maximum quiescent current of 40 μA. In addition, it draws a maximum 500 nA of current during shutdown mode, making it an excellent instrumentation amplifier for battery powered, portable applications.

  • AD5750-1- Industrial Current/Voltage Output Driver with Programmable Ranges
    AD5750-1: Industrial Current/Voltage Output Driver with Programmable Ranges

    The AD5750/AD5750-1 are single-channel, low cost, precision voltage/current output drivers with hardware- or software- programmable output ranges. The software ranges are configured via an SPI-/MICROWIRE™-compatible serial interface. The AD5750/AD5750-1 target applications in PLC and industrial process control. The analog input to the AD5750/AD5750-1 is provided from a low voltage, single-supply MoreRead more

  • AD8227- Wide Supply Range, Rail-to-Rail Output Instrumentation Amplifier
    AD8227: Wide Supply Range, Rail-to-Rail Output Instrumentation Amplifier

    The AD8227 is a low cost, wide supply range instrumentation amplifier that requires only one external resistor to set any gain between 5 and 1000. The AD8227 is designed to work with a variety of signal voltages. A wide input range and rail-to-rail output allow the signal to make full use of the supply rails. Because the input range can also go below the negative supply, small signals near ground MoreRead more
