ISO122JPE4
TEXAS INSTRUMENTS ISO122JPE4 隔离放大器, 精准, 1个放大器, 50 mV, 1.5 kV, ± 4.5V 至 ± 18V, DIP, 8 引脚
The is a Precision Isolation Amplifier incorporating a novel duty cycle modulation-demodulation technique. The signal is transmitted digitally across a 2pF differential capacitive barrier. With digital modulation the barrier characteristics do not affect signal integrity, thus resulting in excellent reliability and good high-frequency transient immunity across the barrier. The ISO122JPE4 is an easy-to-use device. No external components are required for operation. The key specifications are 0.020% maximum nonlinearity, 50kHz signal bandwidth and 200V/°C VOS drift. A power supply range of 4.5 to 18V and quiescent currents of 5mA on VS1 and ±5.5mA on VS2 make the ISO122JPE4 ideal for a wide range of applications.
