LTC2246H
ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
Integral nonlinearity is defi ned as the deviation of a code from a may cause permanent damage to the device. Exposure to any Absolute straight line passing through the actual endpoints of the transfer curve. Maximum Rating condition for extended periods may affect device The deviation is measured from the center of the quantization band. reliability and lifetime.
Note 6:
Offset error is the offset voltage measured from –0.5 LSB when
Note 2:
All voltage values are with respect to ground with GND and OGND the output code fl ickers between 00 0000 0000 0000 and wired together (unless otherwise noted). 11 1111 1111 1111.
