LF353  双路通用 JFET 输入运算放大器说明 This device is a low-cost, high-speed, JFET-input operational amplifier with very low input offset voltage. It requires low supply current yet maintains a large gain-bandwidth product and a fast slew rate. In addition, the matched high-voltage JFET input provides very low input bias and offset currents.The LF353 can be used in applications such as high-speed integrators, digital-to-analog converters, sample-and-hold circuits, and many other circuits.The LF353 is characterized for operation from 0°C to 70°C.特性 Low Input Bias Current...50 pA TypLow Input Noise Current0.01 pA/Hz\ TypLow Input Noise Voltage...18 nV/Hz\ TypLow Supply Current...3.6 mA TypHigh Input Impedance...1012TypInternally Trimmed Offset VoltageGain Bandwidth...3 MHz TypHigh Slew Rate...13 V/us Typ参数 LF353Iq per channel(Max)(mA)3.25  VIO (25 deg C)(Max)(mV)10  CMRR(Min)(dB)70  Vn at 1kHz(Typ)(nV/rtHz)18  IIB(Max)(pA)200  Slew Rate(Min)(V/us)8  Slew Rate(Typ)(V/us)13  GBW(Typ)(MHz)3  Spec'd at Vs(V)+/-15  VIO (Full Range)(Max)(mV)13  Vs(Min)(V)7  Vs(Max)(V)36  Pin/Package8PDIP, 8SOIC  Vio(Max)(mV)13  Open Loop Gain(Min)(dB)88  Offset Drift(Typ)(uV/C)10  IQ Per Amp (+/-)(Max)(mA)3.25  Offset Voltage (+/-)(Max)(mV)13  Number of Channels2  Approx.
