Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: These parameters are guaranteed by design. Thermocouple effects preclude measurements of these voltage levels during automated testing. Note 3: All versions of the LTC2051/LTC2052 are designed, characterized and expected to meet the extended temperature limits of – 40°C and 125°C. The LTC2051C/LTC2052C/LTC2051HVC/LTC2052HVC are guaranteed to meet the temperature limits of 0°C and 70°C. The LTC2051I/LTC2052I/ LTC2051HVI/LTC2052HVI are guaranteed to meet temperature limits of – 40°C and 85°C. The LTC2051H/LTC2051HVH and LTC2052H/LTC2052HVH (LTC2051HV/LTC2052HV) The ● denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VS = ±5V unless otherwise noted. (Note 3) are guaranteed to meet the temperature limits of – 40°C and 125°C. Note 4: The bias current measurement accuracy depends on the proximity of the negative supply bypass capacitors to the device under test. Because of this, only the bias current of channel B (LTC2051) and channels A and B (LTC2052) are 100% tested to the data sheet specifications. The bias currents of the remaining channels are 100% tested to relaxed limits, however, their values are guaranteed by design to meet the data sheet limits. Note 5: This parameter is guaranteed to meet specified performance through design and characterization. It has not been tested. Note 6: The θJA specified for the DD package is with minimal PCB heat spreading metal. Using expanded metal area on all layers of a board reduces this value. |
