Power Supply Recommendations

The power supply pins should be bypassed with a 0.1-µF capacitor and with a 100-pF ceramic chip capacitor close to each power pin. Leadless chip capacitors are preferred because they have low series inductance.

As is the case with all high-speed converters, the ADC14155 is sensitive to power supply noise. Accordingly, the noise on the analog supply pin should be kept below 100 mVP-P.

The VDR pin provides power for the output drivers and may be operated from a supply in the range of 1.6 V to 2 V. This enables lower power operation, reduces the noise coupling effects from the digital outputs to the analog circuitry and simplifies interfacing to lower voltage devices and systems. Note, however, that tOD increases with reduced VDR. A level translator may be required to interface the digital output signals of the ADC14155 to non-1.8-V CMOS devices.

Care should be taken to avoid extremely rapid power supply ramp up rate. Excessive power supply ramp up rate may damage the device.
