The recommended PCB layout for the MAX962EUA involves keeping the input and output traces as short as possible, using a solid ground plane, and placing the device close to the input signal source. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane to minimize noise and EMI.
The values of R1 and R2 depend on the desired gain and bandwidth of the amplifier. A higher value of R1 increases the gain, while a higher value of R2 decreases the bandwidth. The datasheet provides a table to help select the correct values based on the desired gain and bandwidth. Additionally, the Maxim Integrated Products' application note AN1891 provides more detailed guidance on selecting the correct values.
The maximum input signal amplitude that the MAX962EUA can handle without saturating is approximately 2.5Vpp differential. Exceeding this amplitude may cause the amplifier to saturate, resulting in distortion and reduced performance.
To ensure proper biasing for single-supply operation, the MAX962EUA requires a voltage divider network to set the input common-mode voltage to half of the supply voltage. The datasheet provides an example circuit to achieve this. Additionally, the application note AN1891 provides more detailed guidance on single-supply operation.
The recommended power-supply decoupling scheme for the MAX962EUA involves using a 10uF ceramic capacitor in parallel with a 1uF ceramic capacitor, both connected between the supply pin and ground. This helps to filter out high-frequency noise and ensure stable operation.
