J-Fet op-amp is highly precise
14 June 2006, Analogue, Mixed Signal, LSI
High speed/high input impedance and low offset/low drift, are ideal requirements for signal processing in industrial equipment. New Japan Radio has released the NJM411, a single J-Fet input high precision op-amp that achieves high input impedance with 50 pA typ. bias current, and 15 V/μs high-speed slew rate. In addition, this high precision J-Fet input op-amp features low offset voltage (0,8 mV typ.) and low temperature drift (7 μV/°C typ.). With these characteristics the NJM411 is useful for signal processing in instrumentation devices, measurement devices, and a wide range of industrial equipment such as high-speed D/A converter output buffers, sample and hold circuits, sensor amps and precision reference voltage generation amps. Operating voltage is ±5 to ±16 V, and current consumption is 2,0 mA typ. It is equipped with offset voltage adjustment terminal and comes in DIP8 and DMP8 packaging. |
