AC/DC CHARACTERISTICS (CONTINUED)

DC Characteristics

Standard Operating Conditions (unless otherwise specified)

Operating Temperature

–40°C

 TA  +125°C (extended)

All parameters apply across the specified operating ranges unless noted.

VDD = +2.7V to +5.5V. CL = 1 nF, RL = 5 k .

Typical specifications represent values for VDD = 5.5V, TA = +25°C.

Conditions

Note 1:

Resistance is defined as the resistance between the VREF pin and the VSS pin.

INL and DNL are measured at VOUT from Code = 20h (Zero Scale) through Code = 60h (Full Scale).

This specification by design.

Non-linearity is affected by wiper resistance (RW), which changes significantly over voltage and

temperature.

POR/BOR is not rate dependent.

Supply current is independent of VREF current.

See Section 7.1.3.
