How do you match rotary encoder specs with a digital potentiometer?
I saw that several encoder manufacturers use somewhat different terminologies for their product. Furthermore the digital encoder
manufacturers use even more different terminologies.
For example:
Panasonic P12418-ND specs
16 pulse per revolution (PPR)
Single Pole Switch (SPST)
32 Detents
Output signal: Phase A and Phase B
Rating: 1mA, 10VDC (at each bit)
Analog Device AD8402AN10-ND specs
8bit Dual channel digital potentiometer
Resistance: 10kOhm
Interface: SPI, 3-wire serial
Taps: 256
Voltage-Supply: 2.7V~5.5V
Would these two match to work together without too much additional parts?
I found another couple of digital potentiometers:
AD5228BUJZ10RL7CT-ND
AD7376
I read about these being used for DIY DS1802.
