Radiation Hardened 36V Quad Precision Low Power
Operational Amplifier With Enhanced SET Performance
ISL70419SEH
The ISL70419SEH contains four very high precision amplifiers
featuring the perfect combination of low noise vs power
consumption. Low offset voltage, low I_BIAS 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.
Applications for these amplifiers include precision active
filters, medical and analytical instrumentation, precision
power supply controls, and industrial controls.
The ISL70419SEH is offered in a 14 Ld hermetic ceramic
flatpack package. The device is offered in an industry standard
pin configuration and operates over the extended temperature
range from -55°C to +125°C.
