7 / 20 page 7 LT1677 1677fa The ● denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VS = ±15V, VCM = VO = 0V unless otherwise noted. ELECTRICAL CHARACTERISTICS SYMBOL PARAMETER CONDITIONS (Note 6) MIN TYP MAX UNITS THD Total Harmonic Distortion RL = 2k, AV = 1, fO = 1kHz, VO = 10VP-P 0.0006 % tS Settling Time 10V Step 0.1%, AV = +1 5 µs 10V Step 0.01%, AV = +1 6 µs RO Open-Loop Output Resistance IOUT = 0 80 Ω Closed-Loop Output Resistance AV = 100, f = 10kHz 1 Ω IS Supply Current 2.75 3.5 mA 0 °C ≤ TA ≤ 70°C ● 3.00 3.9 mA –40 °C ≤ TA ≤ 85°C ● 3.10 4.0 mA 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: The inputs are protected by back-to-back diodes. Current limiting resistors are not used in order to achieve low noise. If differential input voltage exceeds ±1.4V, the input current should be limited to 25mA. If the common mode range exceeds either rail, the input current should be limited to 10mA. Note 3: A heat sink may be required to keep the junction temperature below absolute maximum. Note 4: The LT1677C and LT1677I are guaranteed functional over the Operating Temperature Range of – 40 °C to 85°C. Note 5: The LT1677C is guaranteed to meet specified performance from 0 °C to 70°C. The LT1677C is 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 LT1677I is guaranteed to meet specified performance from – 40 °C to 85°C. Note 6: Typical parameters are defined as the 60% yield of parameter distributions of individual amplifier; i.e., out of 100 LT1677s, typically 60 op amps will be better than the indicated specification. Note 7: See the test circuit and frequency response curve for 0.1Hz to 10Hz tester in the Applications Information section of the LT1677 data sheet. Note 8: Noise is 100% tested at ±15V supplies. Note 9: Slew rate is measured in AV = – 1; input signal is ±7.5V, output measured at ±2.5V. Note 10: This parameter is not 100% tested. VS = 3V and 5V limits are guaranteed by correlation to VS = ±15V test. Note 11: VS = 5V limits are guaranteed by correlation to VS = 3V and VS = ±15V tests. Note 12: VS = 3V limits are guaranteed by correlation to VS = 5V and VS = ±15V tests. Note 13: Guaranteed by correlation to slew rate at VS = ±15V and GBW at VS = 3V and VS = ±15V tests.
