ISL28117, ISL28217, ISL28417, ISL28417SEH
The ISL28117, ISL28217, ISL28417 and ISL28417SEH are a
family of very high precision amplifiers featuring low noise vs
Features
• Low input offset voltage . . . . . . . . . . . . . . . ±50µV, maximum
power consumption, low offset voltage, low bias current and low
temperature drift making them the ideal choice for applications
requiring both high DC accuracy and AC performance. The
combination of precision, low noise and small footprint provides
the user with outstanding value and flexibility relative to similar
competitive parts.
ISL28417SEH ±110µV, maximum
• Superb offset voltage TC. . . . . . . . . . . . 0.6µV/°C, maximum
ISL28417SEH 1µV/°C, maximum
• Input bias current. . . . . . . . . . . . . . . . . . . . . . ±1nA, maximum
ISL28417SEH ±5nA, maximum
Applications for these amplifiers include precision active
filters, medical and analytical instrumentation, precision
power supply controls and industrial controls.
