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 00 0000 0000 0000 and wired together (unless otherwise noted). 11 1111 1111 1111.

Guaranteed by design, not subject to test. will be clamped by internal diodes. This product can handle input currents
Note 8:
VDD = 3V, fSAMPLE = 65MHz (LTC2298), 40MHz (LTC2297), or of greater than 100mA below GND or above VDD without latchup. 25MHz (LTC2296), input range = 1VP-P with differential drive. The supply
Note 4:
VDD = 3V, fSAMPLE = 65MHz (LTC2298), 40MHz (LTC2297), or current and power dissipation are the sum total for both channels with 25MHz (LTC2296), input range = 2VP-P with differential drive, unless both channels active. otherwise noted.
