Texas Instruments provides a recommended PCB layout in the THS1007CDA evaluation module documentation, which includes guidelines for component placement, routing, and grounding to minimize noise and ensure optimal performance.
The input termination resistors (RIN) should be chosen based on the source impedance and the desired input impedance of the amplifier. A general guideline is to choose RIN = 2 * ZS, where ZS is the source impedance. Additionally, the THS1007CDA datasheet provides a table with recommended RIN values for different source impedances.
The maximum power dissipation of the THS1007CDA is 1.4W. To ensure it doesn't overheat, the device should be operated within the recommended operating temperature range (-40°C to 85°C), and a heat sink or thermal pad may be required depending on the application and ambient temperature. The THS1007CDA datasheet provides a thermal resistance (RθJA) of 45°C/W, which can be used to estimate the junction temperature.
Yes, the THS1007CDA can be used as a single-ended amplifier. To configure it as a single-ended amplifier, connect the non-inverting input (VIN+) to the signal source, and tie the inverting input (VIN-) to a fixed voltage reference (e.g., GND or VCC/2). The output will be single-ended, and the gain will be determined by the feedback resistors.
To ensure EMI compliance, follow proper PCB layout and design practices, such as using a solid ground plane, minimizing trace lengths, and using shielding or filtering components as needed. Additionally, the THS1007CDA datasheet provides guidelines for EMI reduction, including the use of input and output filters, and the selection of components with low electromagnetic radiation.
