VS = ±15V, 0°C ≤ TA ≤ 70°C, unless otherwise noted. Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Typical parameters are defined as the 60% yield of parameter distributions of individual amplifiers, i.e., out of 100 LT2179s (or 100 LT2178s) typically 240 op amps (or 120) will be better than the indicated specification. Note 3: This parameter is tested on a sample basis only. All noise parameters are tested with VS = ±2.5V, VO = 0V. Note 4: This parameter is guaranteed by design and is not tested. Note 5: Power supply rejection ratio is measured at the minimum supply voltage. The op amps actually work at 1.7V supply but with a typical offset skew of –300μV. Note 6: This parameter is not 100% tested. Note 7: During testing at –40°C, the 5V power supply turn-on time is less than 0.5s. Note 8: The LT2178C/LT2179C are designed, characterized and expected to meet the industrial temperature limits, but are not tested at –40°C and 85°C. I-grade parts are guaranteed. The l denotes the specifications which apply over the full operating temperature range. VS = 5V, 0V, VCM = 0.1V, VO = 1.4V, –40°C ≤ TA ≤ 85°C for I-grades, unless otherwise noted.
