Low Noise Precision Op Amps The ADA4075-2 is a dual, high performance, low noise operational Supply 44 V 36 V 12 V to 16 V 5 V amplifier combining excellent dc and ac characteristics on the Single OP27 AD8671 AD8665 AD8605 Analog Devices, Inc., iPolar process. The iPolar process is an AD8675 OP162 AD8655 advanced bipolar technology implementing vertical junction AD8597 AD8691 isolation with lateral trench isolation. This allows for low noise ADA4004-1 performance amplifiers in smaller die size at faster speed and AD797 lower power. Its high slew rate, low distortion, and ultralow Dual OP275 AD8672 AD8666 AD8606 noise make the ADA4075-2 ideal for high fidelity audio and AD8676 OP262 AD8656 high performance instrumentation applications. It is also AD8599 AD8692 especially useful for lower power demands, small enclosures, ADA4004-2 and high density applications. The ADA4075-2 is specified for Quad AD8674 AD8668 AD8608 the 40C to +125C temperature range and is available in a ADA4004-4 OP462 AD8694 standard SOIC package and a 2 mm 2 mm LFCSP package. Rev.
