7.2.2 Programmable Current Source

Figure 7-6 shows the basic configuration for a precision current source using the TLVx888. The circuit provides a configurable current source to a floating load. Figure 7-6 uses a digital-to-analog converter (DAC) to set the current level. For example, a 5V full-scale voltage at the input of the amplifier provides a 100mA current source.
