Texas Instruments recommends a layout that minimizes parasitic inductance and capacitance, with short traces and a solid ground plane. A 4-layer PCB with a dedicated analog ground plane is recommended. See the TI application note 'AN-2025 PCB Layout for Op-Amps' for more details.
The output capacitor should be chosen based on the desired closed-loop bandwidth and stability. A general rule of thumb is to use a capacitor with a value between 10nF to 100nF. A larger capacitor can improve stability but may reduce bandwidth. See the TI application note 'SLVA883A Output Capacitor Selection for Op-Amps' for more details.
Yes, the OPA1632DG4 can be used in a single-supply configuration, but the input common-mode range is limited to VCC-1.5V to VCC-0.5V. The output voltage swing will also be limited to VCC-1.5V to VCC-0.5V. See the TI datasheet for more details on single-supply operation.
To reduce noise and EMI, use a low-impedance power supply, decouple the power pins with 10uF and 100nF capacitors, and use a shielded enclosure. Also, keep the input and output traces away from each other and from other noisy signals. See the TI application note 'SLVA795A EMI and RFI Filtering for Op-Amps' for more details.
The OPA1632DG4 is rated for operation up to 125°C, but the device's performance may degrade at high temperatures. The maximum junction temperature (TJ) should not exceed 150°C. See the TI datasheet for more details on temperature ratings and derating.
