The MAX5440 dual, 40k logarithmic taper volume con- trol features a debounced up/down interface for use with a simple rotary encoder without using a microcontroller. ( C). Each potentiometer has 32 log-spaced tap points with a buffered wiper output and replaces mechanical potentiometers. This design guide helps system designers of galvanically isolated systems to begin designing with TIs broad portfolio of digital isolators and isolated functions in the shortest time possible. This portfolio includes the ISO78xx family of 5.7- kVrms reinforced digital isolators, the ISO73xx family of 3-kVrms digital isolators, and PGA2310 . 2. 15. 0.0004. -126. 0.05. 1000. PDIP, SOIC.
