The MAX987ESA+ requires careful layout and placement to ensure optimal performance. It is recommended to follow the layout guidelines provided in the application note AN4341, which includes recommendations for component placement, routing, and grounding.
To optimize the performance of the MAX987ESA+ in a noisy environment, it is recommended to use proper shielding, grounding, and decoupling techniques. Additionally, consider using a low-pass filter or a ferrite bead to filter out high-frequency noise.
The MAX987ESA+ can handle input voltages up to 5.5V, but it is recommended to operate within the specified input voltage range of 2.7V to 5.5V to ensure optimal performance and reliability.
The gain of the MAX987ESA+ can be programmed using the GAIN pin, which is a digital input that selects one of four gain settings. The gain settings are 20dB, 26dB, 32dB, and 38dB, and can be selected by connecting the GAIN pin to VCC, GND, or a digital signal.
The MAX987ESA+ has a power-down mode that reduces the quiescent current to less than 1μA. To enable power-down mode, the SHDN pin must be pulled low. This can be done by connecting the SHDN pin to GND or a digital signal.
