Texas Instruments provides a recommended PCB layout in the PGA4311U/1KG4 application note (SLAU264). It's essential to follow the layout guidelines to minimize noise, parasitic inductance, and ensure optimal performance.
The PGA4311U/1KG4 datasheet provides guidelines for selecting resistors, capacitors, and inductors. Additionally, Texas Instruments offers a PGA4311U/1KG4 component selection guide (SLAU265) that helps with component selection and optimization.
The recommended power-up sequence is to apply VCC first, followed by VDD, and then the analog input signal. This ensures proper device initialization and prevents potential damage.
Texas Instruments recommends using ESD protection devices, such as the TCTUA016, in conjunction with proper PCB layout and design practices to ensure ESD protection for the PGA4311U/1KG4.
The PGA4311U/1KG4 has a thermal pad that must be connected to a thermal plane on the PCB. Ensure good thermal conductivity between the thermal pad and the thermal plane to prevent overheating and ensure reliable operation.
