Simultaneous Multichannel Update
Internal Power-On Reset
Industry-Standard Pin Configuration The applied external reference input voltage VREF
determines the full-scale output current. An internal
feedback resistor (RFB) provides temperature
tracking for the full-scale output when combined with
an external I-to-V precision amplifier.
A doubled-buffered, serial data interface offers …
