Key Differentiators
- Simultaneous sampling of four channels (vs ADS7800KU/1K)
- Higher sampling rate than delta-sigma alternatives (vs ADS1258-EP)
- Parallel interface for low-latency data transfer (vs ADS1217)
Design Notes
The THS1207IDA requires a clean 5V analog supply (AVDD) and digital supply (DVDD). Use separate analog and digital ground planes to minimize noise coupling. Place 0.1uF and 10uF decoupling capacitors close to each supply pin. The reference output (REFOUT) should be bypassed with a 1uF capacitor to ground to ensure stability.
For optimal performance, route analog input traces away from digital traces to reduce crosstalk. Use differential routing for AINP/AINM pairs to maintain signal integrity. Keep the analog input traces short and shielded if possible. The TSSOP package has a thermal pad that should be connected to the ground plane for heat dissipation.
Ensure the conversion start (CONVST) signal is properly synchronized with the clock to avoid metastability. The parallel data bus should be buffered if driving long traces. Do not exceed the absolute maximum ratings for supply voltage and input voltage. Refer to the datasheet for timing diagrams to avoid setup/hold violations.
