Dual, 256-Tap, Volatile, Low-Voltage
Linear Taper Digital Potentiometer
Note 5: Drive HA with a 1kHz GND to V
Note 6: The wiper settling time is the worst-case 0 to 50% rise time, measured between tap 0 and tap 127. H_ = V
Note 7: Digital timing is guaranteed by design and characterization, not production tested.
Note 8: The SCL clock period includes rise and fall times (t
