Key Differentiators
- 4-channel multiplexer with software configuration (vs TLV0838IPW)
- Differential input capability (vs ADC0834CCWM)
- Low supply voltage operation (2.7V to 3.6V) (vs ADC0834CCWM)
Design Notes
Decouple the VCC pin with a 0.1uF ceramic capacitor placed as close to the pin as possible. Additionally, a 10uF bulk capacitor may be needed if the supply is noisy. The TLV0834 operates from 2.7V to 3.6V; ensure the supply is stable and within this range to avoid conversion errors.
Keep analog input traces short and away from digital signals to minimize noise coupling. Use a ground plane under the ADC to reduce noise. For differential inputs, route the pair closely together to maintain common-mode rejection. Place the reference bypass capacitor close to the REF pin.
Do not exceed the absolute maximum ratings, especially on analog inputs, which should not go below GND or above VCC. Ensure the serial clock is clean and free of glitches. When using the multiplexer, allow sufficient settling time after switching channels before starting a conversion.
