Input
Input
Channel-A sense pin for the negative voltage output load connection.
Channel-A sense pin for the positive voltage output load connection.
6
Channel-A external compensation capacitor connection pin.
The addition of an external capacitor improves the output buffer stability with high capacitive
loads at the OUTA pin by reducing the bandwidth of the output amplifier at the expense of
increased settling time.

Channel-A analog output voltage.
Serial interface data output.
The SDO pin must be enabled before operation by setting the SDO-EN bit. Data are clocked out
of the input shift register on either rising or falling edges of the SCLK pin as specified by the
FSDO bit (rising edge by default).
