• Manufacturer Part Number: MAX5394
• Description: Single, 256-Tap Volatile, SPI, Low-Voltage Linear Taper Digital Potentiometer
• Manufacturer: MAXIM [Maxim Integrated Products]

ELECTRICAL CHARACTERISTICS (continued)
(V
T
Note 2: All devices are production tested at T
Note 3: DNL and INL are measured with the potentiometer configured as a voltage-divider with V
Note 4: R-DNL and R-INL are measured with the potentiometer configured as a variable resistor
Note 5: The wiper resistance is the maximum value measured by injecting the currents given in Note 4 into W with L = GND.
Note 6: Measured at W with H driven with a 1kHz, 0V to V
Note 7: Wiper-settling time is the worst-case 0-to-50% rise time, measured between tap 0 and tap 127. H = V
Note 8: Digital inputs at V
Note 9: Digital timing is guaranteed by design and characterization, and is not production tested.
