CLOCK MODE 11 EXAMPLE 1: COMMAND A SCAN OF CHANNELS 0, 5, AND 10 WITH AN INTERNAL REFERENCE.

Figure 31. Clock Mode 11 Timing Example 1

Clock Mode 01

In clock mode 01, power-up, acquisition, conversion,

and power-down are all initiated by a single CNVST low

pulse and performed automatically using the internal

oscillator. Initiate a scan by writing to the ADC conver-

sion register to indicate which channels to convert.

Then set CNVST low for at least 20ns only once to con-

vert all of the channels selected in the ADC conversion

register. With ADCMON set to 1, the ADC sets the

BUSY output high, powers up, scans all requested

channels, stores the results in the FIFO, and powers

down. After the scan is complete, the BUSY output is

pulled low and the results are available in the FIFO.

Externally Timed Acquisitions and

Conversions

Clock Mode 10

Clock mode 10 is reserved. Do not use this clock mode.

Clock Mode 11

In clock mode 11, conversions are initiated by CNVST

one at a time and performed using the internal oscilla-

tor. See Figures 31 and 32 for a pair of clock mode 11

timing examples. Initiate a conversion by writing to the

ADC conversion register and pulling CNVST low for at

least 1.5μs for each channel converted. Different timing

parameters apply to whether the conversion is a tem-

perature, a voltage using the external reference, or a

voltage using the internal reference conversion.

Internal and external temperature conversions are inter-

nally timed. Set CNVST low for at least 20ns to acquire

a temperature conversion. The BUSY output goes high

while sampling and the internal reference typically

requires 45μs to power up. The temperature sensor cir-

cuit requires 5μs to power up. Temperature conversion

results are available after an additional 30μs. The typi-

cal conversion time of the initial temperature sensor

scan is 80μs. Subsequent temperature scans only take

30μs typically as the internal reference and tempera-

ture sensor circuits are already powered. See the

Electrical Characteristics table for more details.

Set CNVST low for at least 1.5μs to acquire a voltage

conversion using the external reference. The BUSY out-

put goes high while sampling and the conversion

results are available after an additional 3.5μs (typ).

Set CNVST low for at least 50μs to trigger an initial volt-

age conversion using the internal reference. The BUSY

output goes high and the conversion results are avail-

able after an additional 3.5μs typically. Additional volt-

age conversions do not require the acquisition time of

powering up the internal reference. Set CNVST low for

at least 1.5μs to power up the ADC and place it in track

mode. The BUSY output goes high while sampling and

the conversion results are available after 5.6μs.
