FUNCTIONAL DESCRIPTION:

DS3800NOAA1F is a High Voltage Operational Amplifier Module manufactured and designed by General Electric as part of the Mark IV Series used in GE Speedtronic Gas turbine control systems. A high-voltage noninverting amplifier with AV = 17 V/V. An example application circuit is provided below. The board can operate with supply voltages up to ±90 V (180 V) and down to ±6 V (12 V). The high-voltage technology and design enable it to be employed in applications where conventional operational amplifiers are not suitable, such as high-voltage power-supply conditions or when a very high output voltage swing is required. The output may produce up to ±30 mA of current and swing within a few volts of the supply rails at modest current levels.

The non-inverting amplifier circuit, with a closed-loop gain of 17 V/V, has a small signal bandwidth of over 800 kHz at -3 dB. However, large signal bandwidth is likely to be more important in a high-output-voltage application. To determine the maximum large-signal bandwidth in that mode of operation, the operational amplifier's slew rate and peak output swing voltage must be taken into consideration. A high-voltage operational amplifier (op-amp) module typically offers several key features and specifications designed to handle higher voltage requirements than standard op-amps. Here are some common features you might find in such modules:

• High Voltage Capability: Can operate with supply voltages significantly higher than typical op-amps (e.g., up to ±100V or more).
• Wide Supply Voltage Range: Supports a wide range of supply voltages, often beyond the typical ±15V of standard op-amps.
• High Output Voltage Swing: Capable of providing a large output voltage swing close to the supply rails, sometimes referred to as rail-to-rail output.
• High Input Impedance: Maintains a high input impedance to minimize loading effects on preceding circuit stages.
• Low Offset Voltage and Drift: Ensures low offset voltage and drift over temperature variations for accurate DC performance.
• High Slew Rate: Provides a high slew rate to handle rapid changes in the input signal without distortion.
