LT1102 High Speed, Precision, JFET Input Instrumentation Amplifier (Fixed Gain = 10 or 100)
U FEATURES DESCRIPTIO
■ Slew Rate: 30V/μs The LT®1102 is the first fast FET input instrumentation ■ Gain-Bandwidth Product: 35MHz amplifier offered in the low cost, space saving 8-pin ■ Settling Time (0.01%): 3μs packages. Fixed gains of 10 and 100 are provided with ■ Overdrive Recovery: 0.4μs excellent gain accuracy (0.01%) and non-linearity (3ppm). ■ Gain Error: 0.05% Max No external gain setting resistor is required. ■ Gain Drift: 5ppm/°C Slew rate, settling time, gain-bandwidth product, ■ Gain Nonlinearity: 16ppm Max overdrive recovery time are all improved compared to ■ Offset Voltage (Input + Output): 600μV Max competitive high speed instrumentation amplifiers. – Drift with Temperature: 2μV/°C ■ Input Bias Current: 40pA Max Industry best speed performance is combined with ■ Input Offset Current: 40pA Max impressive precision specifications: less than 10pA input – Drift with Temperature (to 70°C): 0.5pA/°C bias and offset currents, 180μV offset voltage. Unlike other FET input instrumentation amplifiers, on the LT1102

and input bias currents do not double with every 10°C rise in temperature. Indeed, at 70 ■ °C ambient temperature the Fast Settling Analog Signal Processing input bias current is only 40pA. ■ Multiplexed Input Data Acquisition Systems ■ High Source Impedance Signal Amplification from , LT, LTC and LTM are registered trademarks of Linear Technology Corporation. High Resistance Bridges, Capacitance Sensors, Photodetector Sensors ■ Bridge Amplifier with < 1Hz Lowpass Filtering
