6 / 16 page  LTC2050/LTC2050HV 6 2050fb ELECTRICAL CHARACTERISTICS (LTC2050HV) The l 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) PARAMETER CONDITIONS C, I SUFFIXES H SUFFIX UNITS MIN TYP MAX MIN TYP MAX Input Offset Voltage (Note 2) ±0.5 ±3 ±0.5 ±3 μV Average Input Offset Drift (Note 2) l ±0.03 ±0.05 μV/°C Long-Term Offset Drift 50 50 nV/√mo Input Bias Current (Note 4) l ±25 ±125 ±300 ±25 ±125 ±4000 pA pA Input Offset Current (Note 4) l ±250 ±500 ±250 ±1000 pA pA Input Noise Voltage RS = 100Ω, 0.01Hz to 10Hz 1.5 1.5 μVP-P Common Mode Rejection Ratio VCM = V– to (V+ – 1.3) VCM = V– to (V+ – 1.3) l 120 115 130 130 120 115 130 130 dB dB Power Supply Rejection Ratio VS = 2.7V to 11V l 120 115 130 130 120 115 130 130 dB dB Large-Signal Voltage Gain RL = 10k 125 120 140 140 125 120 140 140 dB dB Maximum Output Voltage Swing RL = 2k to GND RL = 10k to GND l l ±4.75 ±4.90 ±4.94 ±4.98 ±4.50 ±4.85 ±4.94 ±4.98 V V Slew Rate 2 2 V/μs Gain Bandwidth Product 3 3 MHz Supply Current VSHDN = VIH, No Load VSHDN = VIL l l 1 1.5 25 1 1.6 25 mA μA Shutdown Pin Input Low Voltage (VIL) l V– + 0.5 V– + 0.5 V Shutdown Pin Input High Voltage (VIH) l V+ – 0.5 V+ – 0.5 V Shutdown Pin Input Current VSHDN = V– l –3 –20 –3 –20 μA Internal Sampling Frequency 7.5 7.5 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: These parameters are guaranteed by design. Thermocouple effects preclude measurements of these voltage levels during automated testing. Note 3: All versions of the LTC2050 are designed, characterized and expected to meet the extended temperature limits of – 40°C and 125°C. The LTC2050C/LTC2050HVC are guaranteed to meet the temperature limits of 0°C and 70°C. The LTC2050I/LTC2050HVI are guaranteed to meet the temperature limits of –40°C and 85°C. The LTC2050H/LTC2050HVH 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 supply bypass capacitor to the device under test, especially at ±5V supplies. Because of testing limitations on the placement of this bypass capacitor, the bias current at ±5V supplies is guaranteed by design to meet the data sheet limits, but tested to relaxed limits. |
