Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 6:
Offset error is the offset voltage measured from –1/2LSB when the may cause permanent damage to the device. Exposure to any Absolute output code fl ickers between 0000 0000 0000 0000 and 1111 1111 1111 Maximum Rating condition for extended periods may affect device 1111 in 2’s complement output mode. reliability and lifetime.
Note 7:
Guaranteed by design, not subject to test.
Note 2:
All voltage values are with respect to GND, with GND and OGND
Note 8:
VDD = 3.3V, fSAMPLE = 105MHz (LTC2207) or 80MHz (LTC2206), shorted (unless otherwise noted). input range = 2.25VP-P with differential drive.
Note 3:
When these pin voltages are taken below GND or above VDD, they
Note 9:
Recommended operating conditions. will be clamped by internal diodes. This product can handle input currents
Note 10:
The dynamic current of the switched capacitors analog inputs can of greater than 100mA below GND or above VDD without latchup. be large compared to the leakage current and will vary with the sample rate.
Note 4:
VDD = 3.3V, fSAMPLE = 105MHz (LTC2207), 80MHz (LTC2206)
Note 11:
Leakage current will have higher transient current at power up. differential ENC+/ENC– = 2VP-P sine wave with 1.6V common mode, Keep drive resistance at or below 1kΩ. input range = 2.25VP-P with differential drive (PGA = 0), unless otherwise specifi ed.
Note 5:
Integral nonlinearity is defi ned as the deviation of a code from a “best fi t straight line” to the transfer curve. The deviation is measured from the center of the quantization band. 22076fc 6
