DATASHEET
40V Radiation Hardened and SET Enhanced Precision
Low Power Operational Amplifier
ISL70219ASEH, ISL70419ASEH
Features
The ISL70219ASEH and ISL70419ASEH are a family of very high
precision amplifiers featuring the perfect combination of low
noise vs power consumption. Low offset voltage, low IBIAS current
and low temperature drift making them the ideal choice for
applications requiring both high DC accuracy and AC
performance. The combination of high precision, low noise, low
power and small footprint provides the user with outstanding
value and flexibility relative to similar competitive parts.
• Electrically screened to DLA SMD# 5962-14226
Applications for these amplifiers include precision active
filters, medical and analytical instrumentation, precision
power supply controls and industrial controls.
The ISL70219ASEH is offered in a 10 lead hermetic ceramic
flatpack. The ISL70419ASEH is offered in a 14 lead hermetic
ceramic flatpack package. The devices are packaged in
industry standard pin configurations and operate across the
extended temperature range from -55°C to +125°C.
