High-Voltage (180V) – High-Current (30mA) Operational Amplifier Module

This module provides a platform to evaluate the OPA462 high-voltage, high-current operational amplifier. Multiple component footprints allow the most common circuit configurations. The board accommodates high-voltage and high-current operational amplifier OPA462 from Texas Instruments. A High-Voltage Noninverting Amplifier, AV = 17 V/V. An example application circuit is given below. The board is capable of operating with supply voltages as high as ±90 V (180 V), or as low as ±6 V (12 V). The high-voltage process and design of the OPA462 allow the device to be used in applications where most operational amplifiers cannot be applied, such as high-voltage power-supply conditions, or when there is a need for a very high-output voltage swing. The output is capable of delivering up to ±30 mA output current or swinging within a few volts of the supply rails at moderate current levels. The OPA462 features input overvoltage protection, output current limiting, thermal protection, a status flag, and enable-disable capability. The output swing is 85V with 5V AC signal input and frequency 10Khz. Status Flag is an open-drain active-low output referenced to E/D Com. This pin goes active for either an overcurrent or overtemperature condition. Close (Link) Shunt between GD and E/D Com to enable the output, and Close E/D and E/D Com Jumper J2 to disable the Output.
