X9221A Overview
The X9221A integrates two digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated microcircuit. The digitally controlled potentiometer is implemented using 63 resistive elements in a series array. Between each element are tap points connected to the wiper terminal through switches.
X9221A Key Features
- Two XDCPs in one package
- 2-wire serial interface
- Register oriented format, 8 registers total
- Directly write wiper position -Read wiper position -Store as many as four positions per pot
- Instruction format -Quick transfer of register contents to resistor
- Direct write cell
- Endurance-100,000 writes per bit per register
- Resistor array values
- 2k, 10k, 50k
- Resolution: 64 taps each pot
