LT1102 - High Speed, Precision, JFET Input Instrumentation Amplifier (Fixed Gain= 10 or 100) - Linear Technology（凌力尔特）
功能描述
The LT1102 is the first fast FET input instrumentation amplifier offered in the low cost, space saving 8-pin packages. Fixed gains of 10 and 100 are provided with excellent gain accuracy (0.01%) and non-linearity (3ppm). No external gain setting resistor is required.
Slew rate, settling time, gain-bandwidth product, overdrive recovery time are all improved compared to competitive high speed instrumentation amplifiers.
Industry best speed performance is combined with impressive precision specifications: less than 10pA input bias and offset currents, 180µV offset voltage. Unlike other FET input instrumentation amplifiers, on the LT1102 there is no output offset voltage contribution to total error, and input bias currents do not double with every 10°C rise in temperature. Indeed, at 70°C ambient temperature the input bias current is only 40pA.
特点
Slew Rate: 30V/µs Gain-Bandwidth Product: 35MHz Settling Time (0.01%): 3µs Overdrive Recovery: 0.4µs Gain Error: 0.05% Max Gain Drift: 5ppm/°C Gain Nonlinearity: 16ppm Max Offset Voltage (Input + Output): 600µV Max– Drift with Temperature: 2µV/°C Input Bias Current: 40pA Max Input Offset Current: 40pA Max-Drift with Temperature (to 70°C):0.5pA/°C应用
