(1) RB, RM and RT are decoupled to V
(2) Pins 8, 12, 13, 17, 24 and 32 should be connected to the closest ground pin in order to prevent
(3) When RM is not used, pin 11 can be left open circuit, avoiding the decoupling capacitor. In any
(4) When the analog input signal is AC coupled, an input bias or a clamping level must be applied to VI
The analog and digital supplies should be separated and decoupled.
The external voltage reference generator must be built in such a way that a good supply voltage
ripple rejection is achieved with respect to the LSB value. Eventually, the reference ladder voltages
can be derived from a well regulated V
capacitor.
