For better accuracy, it is important to consider the error related to offset and accuracy gain. Amplifiers input voltage range from 0V to 3.3V and output swing ranges from 1. The device operates on a 225V high voltage supply and a 5.0V low voltage supply. Depending on the current range to be measured and the shunt resistor used, the voltage drop into the shunt resistor can be very small (hundreds of µV). Description: The HV56264 IC is an AECQ100 rated, Quad High Voltage Amplifier Array integrated circuit. Several parameters related to the application must be taken into account. Look into the direction of current flowsĪfter defining the configuration required, ask yourself if the current in your application needs to flow in both directions, in order to choose a bidirectional or unidirectional current sensing.However, the size of the PCB will be larger and accuracy can be lower. Operational amplifiers can be also used, adding 4 external resistors to set the gain. Low-side configuration: Select a current sense amplifier that can work with a common mode voltage close to 0 volts. High-side configuration: Select the current sense amplifier depending of the max common mode voltage (V ICM) required by the application and its power supply (V CC). Define the configuration required for your device.The addition of an output disable function and an over current flag simplify the implementation of robust failure protections on the system level. Onboard protection for the PA164 includes a user-defined, temperature compensated current limit and a temperature sensor output. Thermal efficiency is further enhanced by the PQ style package featuring a heat slug on top that simplifies the mounting of a single heatsink over a single IC or an “array” pattern of these devices. The PA164 uses separate supplies for the amplifier core and the output stage to help optimize overall power dissipation capabilities of 28W of internally generated heat. With a footprint measuring just 22mm x 22mm, this device is capable of providing 1A output current continuously, and up to 4A PEAK on voltage supplies up to 200V. The PA164 is a high density power amplifier IC that utilizes MOSFET technology and a proprietary silicon design to deliver new benchmarks in performance and thermal management for power amplifier ICs.
