Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All voltage values are with respect to ground with GND and OGND
wired together (unless otherwise noted).
Note 3: When these pin voltages are taken below GND or above VDD, they
will be clamped by internal diodes. This product can handle input currents
of greater than 100mA below GND or above VDD without latchup.
Note 4: VDD = 3.3V, fSAMPLE = 105MHz (LTC2222) or 80MHz (LTC2223),
differential ENC+/ENC– = 2VP-P sine wave, input range = 2VP-P with
differential drive, unless otherwise noted.
Note 5: Integral nonlinearity is defined as the deviation of a code from a
straight line passing through the actual endpoints of the transfer curve.
The deviation is measured from the center of the quantization band.
Note 6: Offset error is the offset voltage measured from –0.5 LSB when
the output code flickers between 0000 0000 0000 and 1111 1111 1111 in
2’s complement output mode.
Note 7: Guaranteed by design, not subject to test.
Note 8: VDD = 3.3V, fSAMPLE = 105MHz (LTC2222) or 80MHz (LTC2223),
differential ENC+/ENC– = 2VP-P sine wave, input range = 1VP-P with
differential drive.
