General Description
The DS3501 is a 7-bit, nonvolatile (NV) digital poten-
tiometer featuring an output voltage range of up to 15.5V.
Programming is accomplished by an I
2
C-compatible
interface, which can operate at speeds of up to 400kHz.
External voltages are applied at the RL and RH inputs to
define the lowest and highest potentiometer outputs.
The DS3501 contains an on-chip temperature sensor
and associated analog-to-digital converter (ADC). The
ADC output addresses a 36-word NV lookup table
(LUT). The LUT output can drive the pot directly or be
added to an NV initial-value register (IVR) to drive the
pot. This flexible LUT-based architecture allows the
DS3501 to provide a temperature-compensated poten-
tiometer output with arbitrary slope.
