They are designed to operate from single +5 V supply with 10 V multiplying references for 4-quadrant APPLICATIONS outputs with 6.8 MHz bandwidth. Automatic test equipment The built-in, 4-quadrant resistors facilitate resistance matching Instrumentation and temperature tracking, which minimize the number of Digitally controlled calibration components needed for multiquadrant applications. In addition, Digital waveform generation the feedback resistor (R ) simplifies the I-to-V conversion with FB an external buffer. The AD5547/AD5557 are available in a compact, 38-lead TSSOP package and operate at the extended automotive temperature range of 40C to +125C.
