Description
This circuit consists of two independent, high gain operational amplifiers with frequency compensation implemented internally. It is designed specifically for aerospace and defense applications. The circuit operates from a single power supply over a wide range of voltages. Low power supply drain is independent of the magnitude of the power supply voltage. In linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from a single power supply.

Features
■ Frequency compensation implemented internally
■ Large DC voltage gain: 100 dB
■ Wide bandwidth (unity gain): 1.1 MHz (temperature compensated)
■ Very low supply current/amplifier, essentially independent of supply voltage
■ Low input bias current: 20 nA (temperature compensated)
■ Low input offset current: 2 nA
■ Input common-mode voltage range includes negative rail
■ Differential input voltage range equal to the power supply voltage
■ Large output voltage swing 0 V to (VCC+) - 1.5V
■ Intended for use in aerospace and defense applications: – Dedicated traceability and part marking – Approval documents available for production parts – Adapted extended life time and obsolescence management – Extended product change notification process – Designed and manufactured to meet sub ppm quality goals – Advanced mold and frame designs for superior resilience to harsh environments (acceleration, EMI, thermal, humidity) – Extended screening capability on request – Single fabrication, assembly, and test site – Temperature range (-40 °C to 150 °C)
