4 / 14 page  LT1797 4 1797fb ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C.VS = ±5V, VCM = 0V, VOUT = 0V, pulse power tested unless otherwise specified. (Note 3) SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS RIN Input Resistance Differential Common Mode, VCM = –5V to 3.7V 200 330 100 kΩ MΩ CIN Input Capacitance 4pF Input Voltage Range l –5 5 V CMRR Common Mode Rejection Ratio VCM = –5V to 3.7V VCM = –5V to 5V l l 78 66 96 76 dB dB AVOL Large-Signal Voltage Gain VO = ±4V, RL = 10k l 400 300 1000 V/mV V/mV VOL Output Voltage Swing LOW No Load, Input Overdrive = 30mV ISINK = 5mA ISINK = 10mA l l l –4.99 –4.92 –4.85 –4.97 –4.87 –4.79 V V V VOH Output Voltage Swing HIGH No Load, Input Overdrive = 30mV ISOURCE = 5mA ISOURCE = 10mA l l l 4.84 4.70 4.61 4.95 4.80 4.70 V V V ISC Short-Circuit Current (Note 2) Short to GND 30 50 mA PSRR Power Supply Rejection Ratio VS = ±1.35V to ±6V l 80 90 dB IS Supply Current l 1.40 2.25 3.00 mA mA GBW Gain Bandwidth Product f = 100kHz 0°C ≤ TA ≤ 70°C –40°C ≤ TA ≤ 85°C l l 6.5 5.5 5.0 11 MHz MHz MHz SR Slew Rate AV = –1, RL = ∞, VO = ±4V, Measured at VO = ±2V 0°C ≤ TA ≤ 70°C –40°C ≤ TA ≤ 85°C l l 1.50 1.25 1.10 2.50 V/μs V/μs V/μs tr Output Rise Time 10% to 90%, 0.1V Step, RL = 10k 55 ns tf Output Fall Time 10% to 90%, 0.1V Step, RL = 10k 55 ns tS Settling Time ΔVOUT = 4V to 0.1%, AV = 1 2.6 μs FPBW Full-Power Bandwidth (Note 6) VOUT = 8VP-P 100 kHz 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: A heat sink may be required to keep the junction temperature below absolute maximum. Note 3: The LT1797C is guaranteed to meet 0°C to 70°C specifications and is designed, characterized and expected to meet the extended temperature limits, but is not tested at –40°C and 85°C. The LT1797I is guaranteed to meet specified performance from –40°C to 85°C. Note 4: This parameter is not 100% tested. Note 5: VS = 3V limit guaranteed by correlation to 5V tests. Note 6: Full-power bandwidth is calculated from the slew rate: FPBW = SR/2πVP |
