Key Differentiators
- Easy Drive technology enables high-impedance inputs without external buffers (vs ADS8568)
- 16-channel multiplexer in a compact 32-LFCSP package (vs MCP3461)
- Higher sampling rate than MCP3461 (vs MCP3461)
Design Notes
The AD4695BCPZ operates from a 1.8V supply. Use low-ESR ceramic capacitors (e.g., 0.1uF and 10uF) placed close to the AVDD and DVDD pins to decouple high-frequency noise. A clean, low-noise supply is critical for achieving the specified 16-bit performance.
For optimal performance, route analog inputs away from digital traces and use a solid ground plane. The exposed pad (EP) should be soldered to the PCB ground with multiple vias to enhance thermal dissipation and reduce ground bounce. Keep the reference input (VREF) well-filtered with a 10uF capacitor.
Avoid driving the analog inputs with high source impedance without considering settling time. Even with Easy Drive high-Z mode, excessive source impedance can cause conversion errors. Use a buffer amplifier if the source impedance exceeds the recommended value. Also, ensure the serial interface timing meets the datasheet specifications to avoid data corruption.
