connected to VP

(1) The 220 nF capacitor should be placed close to the VP and PGND pins of the IC.

(2) In non-I2C-bus mode the PROG pin should be left unconnected for 26 dB gain selection or connected via a resistor of

1500 Ω to GND for 16 dB gain selection.

(3) CLIP is not available in the DBS27P version.

(4) In non-I2C-bus mode (ADS1 pin connected to GND) and balanced input source (ADS2 pin connected to GND) selected.

ADS2 is not available in DBS27P version.
