Description

LS7193 and LS7194 are versions of a 3-terminal digital potentiometer with two fixed terminals and a variable wiper terminal with 64 tap positions. Both these parts are available in 20K, 50K and 100K resistor versions. The wiper tap position can be varied with one of the following input signals: up/down clock or A/B quadrature clock. Quadrature inputs signals are debounced to accommodate mechanical quadrature encoders.
• LS7193: A/B quadrature inputs with adjustable debounce delay.
• LS7194: Non-quadrature A(up)/B(down) clock inputs with debounce delay.

Features:

• 64 position wiper control
• Direct interface with Incremental Encoders
• Adjustable debounce for mechanical encoder/switch
• Configurable to operate with non-quadrature clock
• SPI interface for host MCU controllers
• Supply voltage: 3 to 5 volts
• Available in 20K, 50K, and 100K versions
• Qualifies for automotive temperature range
• Available in SOIC-8
