Analog Input Channel 2. Single-ended analog input. T he analog input range on is
±
10 V (AD7890-
10), 0 V to +4.096 V (AD7890-4) and 0 V to +2.5 V (AD7890-2). T he channel to be converted is
selected using the A0, A1 and A2 bits in the control register. T he multiplexer has guaranteed
break-before-make operation.

Voltage Reference Output/Input. T he part can be used with either its own internal reference or with
an external reference source. T he on-chip +2.5 V reference voltage is provided at this pin. When
using this internal reference as the reference source for the part, REF OUT should decoupled to
AGND with a 0.1
μ
F disc ceramic capacitor. T he output impedance of this reference source is typi-
cally 2 k
. When using an external reference source as the reference voltage for the part, the refer-
ence source should be connected to this pin. T his overdrives the internal reference and provides the
reference source for the part. T he REF IN input is buffered on-chip. T he nominal reference voltage
for correct operation of the AD7890 is +2.5 V.
