Description:Analog to Digital Converters - ADC Automotive 24-bit, 7.2-kSPS, 3-ch differential input, delta-sigma ADC with PGA and AC excitation 32-VQFN -40 to 125
The ADS1235QWRHMRQ1 requires careful layout and placement to ensure optimal performance. TI recommends placing the device close to the analog signal sources, using a solid ground plane, and keeping the analog and digital traces separate. Additionally, the device should be placed in a quiet area of the board, away from high-frequency noise sources.
To optimize the ADS1235QWRHMRQ1's performance, consider the following: choose the correct gain setting, adjust the sampling rate, and optimize the analog front-end (AFE) circuitry. Additionally, ensure proper PCB layout, decoupling, and noise reduction techniques are employed. TI provides application notes and design guides to help with optimization.
The ADS1235QWRHMRQ1 is rated for operation up to 125°C. However, high temperatures can affect the device's accuracy, noise performance, and long-term reliability. Ensure proper thermal management, and consider using thermal pads or heat sinks to maintain a safe operating temperature.
To ensure EMC, follow proper PCB design practices, such as using a solid ground plane, separating analog and digital traces, and using shielding or filtering to reduce electromagnetic interference (EMI). Additionally, ensure the device is properly decoupled, and consider using EMI filters or common-mode chokes.
The ADS1235QWRHMRQ1 requires a specific power sequencing to ensure proper operation. TI recommends powering up the analog supply (AVDD) before the digital supply (DVDD), and ensuring that the analog supply is stable before starting conversions.
