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.
For Normal operation connect Jumper/Shunt between GD and E/D Com, Jumper J2 open. Use 0 ohms resistors of 1206 Size instead of capacitors C14 and C15. Many optional components are provided for different applications, all capacitors and resistors are SMD 1206. R5 and R6 resistors are SMD 2512 size.
