The recommended PCB layout for the MAX9601EUP 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 increases the bandwidth. The datasheet provides a table with recommended values for R1 and R2 based on the desired gain and bandwidth. It's also recommended to use resistors with a 1% tolerance to ensure accurate gain and bandwidth.
The maximum input signal amplitude that the MAX9601EUP can handle without saturating is approximately 2.5Vpp differential. Exceeding this amplitude may cause the amplifier to saturate, resulting in distortion and reduced accuracy.
To ensure that the MAX9601EUP is operating within its recommended operating conditions, it's essential to monitor the device's power supply voltage, temperature, and input signal amplitude. The device should be operated within the recommended voltage range of 2.7V to 5.5V, and the temperature should be kept within the range of -40°C to +125°C. Additionally, the input signal amplitude should be kept within the recommended range to prevent saturation.
The typical settling time of the MAX9601EUP is approximately 10ns to 90% of the final output value. This settling time is dependent on the gain and bandwidth of the amplifier, as well as the input signal frequency and amplitude.
