Digital Potentiometers (14 Pins)
LS7190; LS7191; LS7192
LS7190, LS7191 and LS7192 are versions of a 3-terminal digital potentiometer with two fixed terminals and a variable wiper terminal with 64 tap positions. All three parts are available in 20K, 50K and 100K resistor versions. The wiper tap position can be varied with any of the following available input signals: up/down clock or A/B quadrature clock or direct data transfer over SPI bus. Quadrature inputs signals are debounced to accommodate mechanical quadrature encoders.
