Note 2: The inputs are protected by back-to-back diodes. If the differential input voltage exceeds 1.4V, the input current should be limited to less than 10mA. Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefinitely. Note 4: The LT6220C/LT6221C/LT6222C and LT6220I/LT6221I/LT6222I are guaranteed functional over the temperature range of –40°C and 85°C. Note 5: The LT6220C/LT6221C/LT6222C are guaranteed to meet specified performance from 0°C to 70°C. The LT6220C/LT6221C/LT6222C are designed, characterized and expected to meet specified performance from –40°C to 85°C but is not tested or QA sampled at these temperatures. The LT6220I/LT6221I/LT6222I are guaranteed to meet specified performance from –40°C to 85°C. Note 6: Minimum supply voltage is guaranteed by power supply rejection ratio test. Note 7: Output voltage swings are measured between the output and power supply rails. Note 8: This parameter is not 100% tested. Note 9: Matching parameters are the difference between amplifiers A and D and between B and C on the LT6222; between the two amplifiers on the LT6221. Note 10: Thermal resistance (θJA) varies with the amount of PC board metal connected to the package. The specified values are for short traces connected to the leads. If desired, the thermal resistance can be substantially reduced by connecting Pin 2 of the LT6220CS5/LT6220IS5 or the underside metal of DD packages to a larger metal area (VS– trace). ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the –40°C ≤ T A ≤ 85°C temperature range. VS = ±5V, VCM = 0V, VOUT = 0V, unless otherwise noted. (Note 5) |
