Texas Instruments recommends a 4-layer PCB with a solid ground plane, and placing the device close to the analog signal sources to minimize noise. Additionally, it's recommended to keep the analog and digital grounds separate and connect them at a single point.
To optimize performance in a noisy environment, use a low-pass filter on the input signals, keep the device away from high-frequency sources, and use shielding or guard rings to reduce electromagnetic interference (EMI). Additionally, consider using a ferrite bead or a common-mode choke to filter out high-frequency noise.
The LMC6772BIMX is rated for operation from -40°C to 125°C, but it's recommended to operate within the -20°C to 85°C range for optimal performance and reliability.
The LMC6772BIMX has a rail-to-rail output stage, but it's recommended to limit the output voltage swing to within 1V of the supply rails to ensure optimal linearity and distortion performance.
Texas Instruments recommends using a 10uF ceramic capacitor in parallel with a 1uF ceramic capacitor, both placed close to the device's power pins, to decouple the power supply and reduce noise.
