TI I G CHARACTERISTICS SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS t16 HBEN ↓ to Low Byte Data Valid CL = 100pF (LTC1277 Only) q 45 100 ns t17 HBEN ↑ to RD↓ Setup Time (Note 10) (LTC1277 Only) q 10 ns t18 RD ↑ to HBEN↓ Setup Time (Note 10) (LTC1277 Only) q 10 ns The q denotes specifications which apply over the full operating temperature range; all other limits and typicals TA = 25°C. Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: All voltage values are with respect to ground with DGND and AGND wired together and VLOGIC is tied to VDD in LTC1277 (unless otherwise noted). Note 3: When these pin voltages are taken below VSS (ground for unipolar mode) or above VDD, they will be clamped by internal diodes. This product can handle input currents greater than 60mA below VSS (ground for unipolar mode) or above VDD without latch-up. Note 4: When these pin voltages are taken below VSS (ground for unipolar mode), they will be clamped by internal diodes. This product can handle input currents greater than 60mA below VSS (ground for unipolar mode) without latch-up. These pins are not clamped to VDD. Note 5: VDD = 5V (VSS = – 5V for bipolar mode), VLOGIC = VDD (LTC1277), fSAMPLE = 100ksps, tr = tf = 5ns unless otherwise specified. Note 6: Linearity, offset and full-scale specifications apply for unipolar and bipolar modes. Note 7: 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 8: For LTC1274, bipolar offset is the offset voltage measured from – 0.5LSB when the output code flickers between 0000 0000 0000 and 1111 1111 1111. For LTC1277, bipolar offset voltage is measured from – 0.5LSB when the output code flickers between 0111 1111 1111 and 1000 0000 0000. Note 9: The AC tests apply to bipolar mode only and the S/(N + D) is 71dB (typ) for unipolar mode at 100kHz input frequency. Note 10: Guaranteed by design, not subject to test. Note 11: Recommended operating conditions. Note 12: AIN must not exceed VDD or fall below VSS by more than 50mV to specified accuracy. Note 13: The falling CONVST edge starts a conversion. If CONVST returns high at a bit decision point during the conversion it can create small errors. For best performance ensure that CONVST returns high either within 400ns after conversion start (i.e., before the first bit decision) or after BUSY rises (i.e., after the last bit test). See timing diagrams Modes 1a and 1b (Figures 13, 14).
