LTC2230/LTC2231
ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 6:
Offset error is the offset voltage measured from –0.5 LSB when the may cause permanent damage to the device. Exposure to any Absolute output code flickers between 00 0000 0000 and 11 1111 1111 in 2’s Maximum Rating condition for extended periods may affect device complement output mode. reliability and lifetime.
Note 7:
Guaranteed by design, not subject to test.
Note 2:
All voltage values are with respect to ground with GND and OGND
Note 8:
Recommended operating conditions. wired together (unless otherwise noted).
Note 9:
VDD = 3.3V, fSAMPLE = 170MHz (LTC2230) or 135MHz (LTC2231),
Note 3:
When these pin voltages are taken below GND or above VDD, they will differential ENC+/ENC– = 2VP-P sine wave, input range = 1VP-P with differential be clamped by internal diodes. This product can handle input currents of drive, output CLOAD = 5pF. greater than 100mA below GND or above VDD without latchup.
Note 10:
SNR minimum and typical values are for LVDS mode. Typical values
Note 4:
VDD = 3.3V, fSAMPLE = 170MHz (LTC2230) or 135MHz (LTC2231), for CMOS mode are typically 0.1dB lower. LVDS outputs differential, ENC+/ENC– = 2VP-P sine wave, input range =
Note 11:
SFDR minimum values are for LVDS mode. Typical values are for 2VP-P with differential drive, unless otherwise noted. both LVDS and CMOS modes.
Note 5:
Integral nonlinearity is defined as the deviation of a code from a
Note 12:
SINAD minimum and typical values are for LVDS mode. Typical straight line passing through the actual endpoints of the transfer curve. The values for CMOS mode are typically 0.1dB lower. deviation is measured from the center of the quantization band.
