The ISL70419SEH contains four 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.

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.
