LTC2226H
ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
Integral nonlinearity is defined 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 flickers between 0000 0000 0000 and 1111 1111 1111. wired together (unless otherwise noted).
Note 7:
Guaranteed by design, not subject to test.
Note 3:
When these pin voltages are taken below GND or above VDD, they
Note 8:
VDD = 3V, fSAMPLE = 25MHz, input range = 1VP-P with will be clamped by internal diodes. This product can handle input currents differential drive. of greater than 100mA below GND or above VDD without latchup.
Note 9:
Recommended operating conditions.
Note 4:
VDD = 3V, fSAMPLE = 25MHz, input range = 2VP-P with differential drive, unless otherwise noted.
