40V Precision Low Power Operational Amplifiers
ISL28117, ISL28217
Features
• Low Input Offset . . . . . . . . . . . . . . ±50µV, Max.
• Superb Offset TC . . . . . . . . . . . . 0.6µV/°C, Max.
• Input Bias Current . . . . . . . . . . . . . . ±1nA, Max.
The ISL28117 and ISL28217 are a family of very high
precision amplifiers featuring low noise vs power
consumption, low offset voltage, low I
current and
BIAS
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.
