The LT1012 combines picoampere bias currents (which are maintained over the full –55 °C to 125°C temperature range), microvolt offset voltage (and low drift with time and temperature), low voltage and current noise, and low power dissipation. The LT1012 achieves precision operation on two Ni-Cad batteries with 1mW of power dissipation. Extremely high common mode and power supply rejection ratios, practically unmeasurable warm-up drift, and the ability to deliver 5mA load current with a voltage gain of one million round out the LT1012’s superb precision specifications. The all around excellence of the LT1012 eliminates the necessity of the time consuming error analysis procedure of precision system design in many applications; the LT1012 can be stocked as the universal internally compensated precision op amp. s Replaces OP-07 While Saving Power s Precision Instrumentation s Charge Integrators s Wide Dynamic Range Logarithmic Amplifiers s Light Meters s Low Frequency Active Filters s Thermocouple Amplifiers ± 250V Common Mode Range Instrumentation Amplifier (AV = 1) Picoamp Input Current, Microvolt Offset, Low Noise Op Amp Typical Distribution of Input Offset Voltage +IN –IN – + 2 3 4 LT1012 7 6 LT1012A • TA01 R3 1M R2 20k R4 19.608k R1 1M R5 975k – 6V TO –18V 6V TO 18V R6 25k OUT R1 TO R6: VISHAY 444 ACCUTRACT THIN FILM OPTIONAL CMRR TRIM 50k SIP NETWORK : VISHAY 444 PIN NUMBERS VISHAY INTERTECHNOLOGY, INC 63 LINCOLN HIGHWAY MALVERN, PA 19355 COMMON MODE REJECTION RATIO = 74dB (RESISTOR LIMITED) WITH OPTIONAL TRIM = 130dB OUTPUT OFFSET (TRIMMABLE TO ZERO) = 500 µV OUTPUT OFFSET DRIFT = 10 µV/°C INPUT RESISTANCE = 1M COMMON MODE INPUT ±250V X 3 4 1 2 7 6 5 INPUT OFFSET VOLTAGE ( µV) 120 160 200 LT1012A • TA02 80 40 0 –40 –20 20 40 0 1140 UNITS FROM THREE RUNS VS = ±15V TA = 25°C VCM = 0V Protected by U.
