LTC1151C PARAMETER CONDITIONS MIN TYP MAX UNITS Maximum Output Voltage Swing RL = 10k, TA = 25°C ±13.5 ±14.50 V RL = 10k q +10.5/–13.5 V RL = 100k ±14.95 V Slew Rate RL = 10k, CL = 50pF 2.5 V/ µs Gain-Bandwidth Product 2 MHz Supply Current per Amplifier No Load, TA = 25°C 0.9 1.5 mA No Load q 2.0 mA Internal Sampling Frequency 1000 Hz Input Offset Voltage TA = 25°C (Note 3) ±0.05 ±5 µV Average Input Offset Drift (Note 3) q ±0.01 ±0.05 µV/°C Long Term Offset Voltage Drift 50 nV/ √mo Input Offset Current TA = 25°C ±10 100 pA Input Bias Current TA = 25°C ±550 pA Input Noise Voltage RS = 100Ω, 0.1Hz to 10Hz 2.0 µVP-P RS = 100Ω, 0.1Hz to 1Hz 0.7 µVP-P Input Noise Current f = 10Hz (Note 4) 1.3 fA/ √Hz Input Voltage Range Positive 2.7 3.2 V Negative 0 – 0.3 V Common-Mode Rejection Ratio VCM = 0V to 2.7V 110 dB Power Supply Rejection Ratio VS = ±2.375V to ±16V q 110 130 dB Large-Signal Voltage Gain RL = 10k, VOUT = 0.3V to 4.5V q 115 140 dB Maximum Output Voltage Swing RL = 10k to GND 4.85 V RL = 100k to GND 4.97 V Slew Rate RL = 10k, CL = 50pF 1.5 V/ µs Gain Bandwidth Product 1.5 MHz Supply Current per Amplifier No Load, TA = 25°C 0.5 1.0 mA q 1.5 mA Internal Sampling Frequency 750 Hz The • denotes the specifications which apply over the full operating temperature range. Note 1: Absolute Maximum Ratings are those values beyond which life of the device may be impaired. Note 2: Connecting any terminal to voltages greater than V+ or less than V– may cause destructive latch-up. It is recommended that no sources operating from external supplies be applied prior to power-up of the LTC1151. Note 3: These parameters are guaranteed by design. Thermocouple effects preclude measurement of these voltage levels in high speed automatic test systems. VOS is measured to a limit determined by test equipment capability. Note 4: Current Noise is calculated from the formula: IN = √(2q • Ib) where q = 1.6 × 10–19 Coulomb. VS = 5V, TA = Operating Temperature Range, unless otherwise specified. |
