The ISL70419SEH and ISL73419SEH contain 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 make it 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 ISL7x419SEH are offered in a 14 Ld hermetic ceramic flatpack package. These devices are offered in an industry-standard pin configuration and operate across the extended temperature range from -55 °C to +125 °C.
