DIGITAL INPUTS AND OUTPUTS
Typical specifications represent average readings at 25°C and V
Resistor position nonlinearity error, R-INL, is the deviation from an ideal value measured between the maximum resistance and the minimum resistance wiper
positions. R-DNL measures the relative step change from the ideal between successive tap positions. Parts are guaranteed monotonic.
V
INL and DNL are measured at V
of ±1 LSB maximum are guaranteed monotonic operating conditions.
The A, B, and W resistor terminals have no limitations on polarity with respect to each other.
Guaranteed by design and not subject to production test.
Measured at the A terminal. The A terminal is open circuited in shutdown mode.
The minimum voltage requirement on the V

pull-up resistors.
Different from operating power supply; power supply for OTP is used one time only.
Different from operating current; supply current for OTP lasts approximately 400 ms for use one time only.
See Figure 26 for the energy plot during OTP program.
