11 / 24 page  LT6236/LT6237 11 623637f ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the –40°C < T A < 125°C temperature range. VS = ±5V, VCM = VOUT = 0V, ENABLE = 0V, unless otherwise noted.

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. Inputs are protected by back-to-back diodes. If the differential input voltage exceeds 0.7V, the input current must be limited to less than 40mA. 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 LT6236C/LT6236I/LT6236H and the LT6237C/LT6237I/LT6237H are guaranteed functional over the temperature range of –40°C and 125°C. Note 5. The LT6236C/LT6237C are guaranteed to meet specified performance from 0°C to 70°C. The LT6236I/LT6237I are guaranteed to meet specified performance from –40°C to 85°C. The LT6236H/LT6237H are guaranteed to meet specified performance from –40°C to 125°C. The LT6236C/LT6237C are designed, characterized and expected to meet specified performance from –40°C to 85°C, but are not tested or QA sampled at these temperatures. Note 6. Matching parameters are the difference between the two amplifiers of the LT6237. Note 7. Minimum supply voltage is guaranteed by power supply rejection ratio test. Note 8. Output voltage swings are measured between the output and power supply rails. Note 9. Full-power bandwidth is calculated from the slew rate: FPBW = SR/2πVP Note 10. This parameter is not 100% tested. |
