Typical values represent average readings at 25°C, V
Resistor position nonlinearity error. R-INL is the deviation from an ideal value measured between the R
code 0x000. R-DNL measures the relative step change from ideal between successive tap positions. The specification is guaranteed in resistor performance mode, with
a wiper current of 1 mA for V
Resistor performance mode (see the Resistor Performance Mode section). The terms resistor performance mode and R-Perf mode are used interchangeably.
Guaranteed by design and characterization, not subject to production test.
INL and DNL are measured at V
of ±1 LSB maximum are guaranteed monotonic operating conditions.
Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other. Dual-supply operation enables ground-
referenced bipolar signal adjustment.
Different from operating current; supply current for fuse program lasts approximately 550 μs.
Different from operating current; supply current for fuse read lasts approximately 550 μs.
