Once conversion is completed, the device goes into the
programmed power mode until a new control byte is
written.
The power-up delay is dependent on the power-down
state. Software low-power modes will be able to start
conversion immediately when running at decreased
clock rates (see Power-Down Sequencing). Upon
power-on reset, when exiting software full power-down
mode, or when exiting hardware shutdown, the device
goes immediately into full-power mode and is ready to
convert after 2s when using an external reference.
When using the internal reference, wait for the typical
power-up delay from a full power-down (software or
hardware) as shown in Figure 8.
Software Power-Down
Software power-down is activated using bits PD1 and
PD0 of the control byte. When software power-down is
asserted, the ADC completes the conversion in
300ksps/400ksps, Single-Supply, 4-Channel,
Serial 12-Bit ADCs with Internal Reference

BIT
NAME
DESCRIPTION
7(MSB)
START
The first logic 1 bit after CS goes low defines the beginning of the control byte.
6
SEL2
These three bits select which of the eight channels are used for the conversion (Tables 1 and 2).
5
SEL1
4
SEL0
3
UNI/BIP
1 = unipolar, 0 = bipolar. Selects unipolar or bipolar conversion mode. In unipolar mode, an
analog input signal from 0 to VREF can be converted; in bipolar mode, the differential signal can
range from -VREF/2 to +VREF/2.
2
SGL/DIF
1 = single ended, 0 = pseudo-differential. Selects single-ended or pseudo-differential conver-
sions. In single-ended mode, input signal voltages are referred to COM. In pseudo-differential
mode, the voltage difference between two channels is measured (Tables 1 and 2).

Select operating mode.
