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
Datasheet - production data

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)
Applications
• Aerospace and defense
• Harsh environments
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.
