Long shots, short shots, and hip shots

... the resistance of the unknown driver path plus the known test resistor.The low-offset op amps buffering the ground-sense voltage had unity-gain bandwidths much lower than 50 MHz. When receiving the new 50-MHz clock signals on their inputs, they were rectifying instead of amplifying—generating an offset voltage that the system interpreted as additional resistance. Adding a lowpass RC filter on the ground...

Convert 1 to 5V signal to 4- to 20-mA output

... matched resistor network helps to solve these issues in a simple circuit that requires no trim adjustments but achieves a total error of less than 0.2% (Figure 1). The circuit uses two amplifier stages to exploit the unique matching characteristics of the LT5400. The first stage applies a 1 to 5V output—typically, from a DAC—to the noninverting input of op amp IC1A. This voltage sets the current through R1...
