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 DGND, AGND1 and AGND2 wired together (unless otherwise noted). Note 3: When these pin voltages are taken below ground or above VANA = VDIG = VDD, they will be clamped by internal diodes. This product can handle input currents of greater than 100mA below ground or above VDD without latch-up. Note 4: When these pin voltages are taken below ground, they will be clamped by internal diodes. This product can handle input currents of 90mA below ground without latchup. These pins are not clamped to VDD. Note 5: VDD = 5V, fSAMPLE = 100kHz, tr = tf = 5ns unless otherwise specified. Note 6: Linearity, offset and full-scale specifications apply for a VIN input with respect to ground. Note 7: Integral nonlinearity is defined as the deviation of a code from a straight line passing through the actual end points of the transfer curve. The deviation is measured from the center of the quantization band. The ● denotes specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. (Note 5) The ● denotes specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. (Note 5) The ● denotes specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. (Note 5) |
