This amplifier offers an adjustable current limit, a thermal shutdown indicator, and enable/shutdown features. The PA is configured with an inverting gain of 7 V/V, has a low-pass filter response, and maintains excellent linearity and low distortion throughout its bandwidth. The PA block is shown in Figure 1.

OPA521 Device Functional Block Diagram The OPA521 can be used as a line driver for narrow band power line communcations (PLC). 1.2 High Power Warning CAUTION The OPA521 evaluation module contains a high voltage, high current power amplifier. Please use precautions when operating the OPA521 EVM. The possibility for accidental electrical shock increases with increased potential difference and the user must take precautions to avoid contact with the PC board when live voltage is present. If circuit probing is required and voltages are present, it is a best practice to apply the “one hand rule.” Use an insulated probe and only one hand when probing the live circuit. Keep the other hand away from the circuit and any metal contacts in the immediate area through which current could flow. Power operational amplifiers can generate a lot of heat under some operating conditions. That excess heat must be conducted away from amplifier in order to assure correct operation and long life. A passive heat sink, or heat sink/fan assembly, may be employed. Heat sinks can become hot to the touch if the power being dissipated as heat is high relative to the heat sink’s ability to dissipate it. When that occurs contacting the heat sink with bare skin may cause a user to become startled, or possibly receive a burn. Therefore, it is best to avoid any contact with the heat sink when the circuit is in use, or cooling down after use.

The EVM is based on a 5-inch × 3.5-inch (12.7-cm × 8.9-cm) PC board that accommodates the QFN-20 package with bottom side power pad. An illuminated red LED (D4) indicates that the OPA521 is operating normally and when turned off it indicates that the device is in thermal shutdown. When off a red LED (D5) indicates the OPA521 output is current limited. The output current limits can be selected by positioning the shunt on jumper JMP4 (J12) to ground for maximum current output or to R10 which can be populated to the appropriate value with the equations in Equation 2. 1.4 Supply Voltage Considerations for the OPA521EVM The OPA521 device is able to operate with a single supply, ground, and V+ (7 V -24 V). Although the supply range of the OPA521 device can operate up to 24-V single supply, the EVM has been designed to be used up to 17.8-V single supply range due to the TVS diode (D1) attached on the supply to ground (see Section 1.5). Two PA power-supply pins and two PA ground pins are available to provide a path for the high currents associated with driving the low impedance of the ac mains. Connecting the three PA supply pins together is recommended. TI also recommends placing a 47-μF to 100-μF bypass capacitor in parallel with a 100nF capacitor as close as possible to the device. Take care when routing the high-current ground lines on the PCB to avoid creating voltage drops in the PCB ground that may vary with changes in load current. The OPA521 operational amplifier also requires a digital supply voltage between 2 V and 5.5 V above the negative supply applied to the amplifier. A fixed output regulator TPS7A1633 was used on the EVM for a 3.3-V supply to fulfill this requirement. 1.5 Input, Output, and Power Supply Protection Power-line communications are frequently harsh operating environment for electrical components connected to the ac line. Noise or surges from electrical anomalies such as lightning, capacitor bank switching, inductive switching, or other grid fault conditions can damage high-performance integrated circuits if they are not properly protected. The OPA521 can survive even these harsh conditions, but several simple recommendations must be followed. One recommendation is to clamp as much of the electrical disturbance before it reaches the OPA521 device with a multi-layer approach using metal-oxide varistors (MOVs), transient voltage suppression diodes (TVSs), Schottky diodes, and a zener diode. This EVM has current-steering diodes (B130-13-F), D2 and D3, which were placed at the output of the OPA521. In the unlikely event a transient surge increases the output pin of the PA beyond its powersupply rail, low-drop Schottky diodes can steer the current around the OPA521 to ground. Maintaining a low forward voltage drop on the Schottky diode is recommended for maximum protection. If the Schottky diode that connects the output of the PA to the power-supply rail turns on and becomes forward-biased, it is important to steer the current to ground without significantly disturbing the PA power-supply voltage. Placing a zener or transient voltage suppressor (TVS) diode at the PA power-supply pins to ground provides a low-impedance path for surges that attempt to raise the power-supply voltage beyond the absolute maximum rated voltage for the OPA521. The OPA521EVM has a TVS diode (SMCJ16A-TP) populated in socketD1. When choosing a suitable TVS or zener-diode, several points must be considered – such as the power supply voltage levels during normal operation and the expected electrical overstress (EOS). TVS diode was used on D1 and limits the operating supply to a maximum limit of 15 V. D1 can be replaced with a TVS diode with A procedure how to select a well-fitting TVS can be found in the following blog: Electrical overstress in a nutshell. 4 OPA521EVM User's Guide SBOU208 – June 2018 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated Overview www.ti.com 1.6 Jumpers A brief description of the basic jumper functions is shown in Table 1.

The CIN and PA combination has a band-pass response because of the inherent lowpass transfer function from the PA. The value of the high-pass cutoff frequency is determined by CIN reacting with the input resistance of the PA circuit, and can be determined by Equation 1: where • • CIN = external input capacitor fHP = desired high-pass cutoff frequency (1) For example, setting CIN to 3.3 nF results in a high-pass cutoff frequency of 2.9 kHz. Determine the voltage rating for CIN to withstand operation up to the PA power-supply voltage. 2.3 Current Limit RSET Value The ILIM pin (pin 12) provides a resistor-programmable output current limit for the PA block. Equation 2 determines the value of the external RSET resistor attached to this pin. where: where • • 3 ILIM =the value of the desired current limit for the PA RSET = the value of the external resistor connected between pin 12 and ground, (2) Getting Started This section explains the purpose of the connectors and jumpers, how to configure the EVM and how to make use of the features provided by the EVM. 3.1 Power Supply The OPA521EVM is configured only use a single 7-V to 24-V supply, power is provided to the EVM through 2 banana jacks: AVDD and GND. The power supply must provide the total anticipated current required in the application. The OPA521 can supply a continuous dc current of 1.9 A, but it is recommended that the supply should be capable of providing at least 2× the anticipated continuous current to account for peak current conditions. Make sure any cables used to carry high current are rated for such service. Even though the OPA521 operational amplifier is specified for an absolute maximum supply voltage of 26 V, TI recommends that not more than 25 V be applied to the EVM to avoid damage to other parts. For this reason TVS diode is attached from supply to ground and limits the operating supply to 18V maximum. 3.2 Inputs The input to the EVM must be an AC signal source such as a signal generator. Note that 50-Ω termination resistors R1 can be utilized on the EVM by placing a short bar on JMP2 (J3). Excessive power dissipation, under high input voltage conditions, could result in their failure and destruction. The signal presented to the inverting OPA521 input pin –IN is selected through JMP1 (J5). 3.3 Outputs Output signals derived from the EVM may be monitored by whatever means required by the user. Often, an oscilloscope provides a convenient way to observe the output waveform from the OPA521. The output is brought to a BNC connector (J6) which is intended for the instrument connection and to carry high output current. The load is intended to be located external to the EVM. The OPA521 can drive a variety of load types which includes resistors, motors, transducers, etc. some of which may have to dissipate significant power, or be physically too large to reside on the EVM.

JMP3 (J10) allows 3 options for placing a shorting bar jumper, that allow the user to Enable, Disable, or use an external waveform generator. 3.5 Current Limitation Capability The OPA521 EVM provides means to limit the maximum output current that it can provide. A resistance between the ground and the amplifier`s ILIM pin is used to set the maximum output current limit. This resistance can be utilized by JMP4 (J12) to set the current limit by positioning the jumper to utilize R10. As an example, if the designer wants to limit the output current to 1 A, then R10 must be populated with a resistance of 11.584 kΩ which using standard resistance values is approximately 11.5 Ω. 3.6 LED Indicator The LED indicators are explained in and Section 1.3. 4 Appendix Figure 3 shows the complete schematics of the OPA521 EVM.
