RT2904WH：Dual general purpose operational amplifier

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.

Key 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)
