Input pin to supply the negative supply voltage for the 20X gain instrumentation amplifier and
coarse/fine charge buffers. May be tied to AGND if AIN+ and AIN- inputs are centered around
+2.5 V; or it may be tied to a negative supply voltage (-2.1 V typical) to allow the amplifier to
handle low level signals more negative than ground. When using the CS5528 in either the
25 mV, 55 mV or 100 mV range, the analog inputs are expected to be ground referenced;
therefore, NBV must be between -1.8 to -2.5 to ensure proper operation.
Square wave output used to provide energy for the charge pump.
Positive analog supply voltage. Nominally +5 V.
Positive digital supply voltage. Nominally +3.0 V or +5 V.
Analog Ground.
Digital Ground.
