COMPARATOR (ADS1114/15 ONLY)

The

ADS1114/5

are

each

equipped

with

a

customizable comparator that can issue an alert on

the ALERT/RDY pin. This feature can significantly

reduce external circuitry for many applications. The

comparator

can

be

implemented

as

either

a

traditional comparator or a window comparator via the

COMP_MODE bit in the Config register. When

implemented

as

a

traditional

comparator,

the

ALERT/RDY pin asserts (active low by default) when

conversion data exceed the limit set in the high

threshold register. The comparator then deasserts

when the input signal falls below the low threshold

register value. In window comparator mode, the

ALERT/RDY pin asserts if conversion data exceed

the high threshold register or fall below the low

threshold register.

In either window or traditional comparator mode, the

comparator can be configured to latch once asserted

by the COMP_LAT bit in the Config register. This

setting causes the assertion to remain even if the

input signal is not beyond the bounds of the threshold

registers. This latched assertion can be cleared by

issuing an SMBus alert response or by reading the

Conversion register. The COMP_POL bit in the

Config register configures the ALERT/RDY pin as

active high or active low. Operational diagrams for

Configured as a Traditional Comparator

the comparator modes are shown in Figure 28 and

Figure 29 .

The comparator can be configured to activate the

ALERT/RDY pin after a set number of successive

readings exceed the threshold. The comparator can

be configured to wait for one, two, or four readings

beyond

the

threshold

before

activating

the

ALERT/RDY pin by changing the COMP_QUE bits in

the Config register. The COMP_QUE bits can also

disable the comparator function.

CONVERSION READY PIN (ADS1114/5 ONLY)

The ALERT/RDY pin can also be configured as a

conversion ready pin. This mode of operation can be

realized if the MSB of the high threshold register is

set to '1' and the MSB of the low threshold register is

set to '0'. The COMP_POL bit continues to function

and the COMP_QUE bits can disable the pin;

however, the COMP_MODE and COMP_LAT bits no

longer control any function. When configured as a

conversion ready pin, ALERT/RDY continues to

require a pull-up resistor. When in continuous

conversion mode, the ADS1113/4/5 provide a brief

(~8µs) pulse on the ALERT/RDY pin at the end of

each conversion. When in single-shot shutdown

mode, the ALERT/RDY pin asserts low at the end of

a conversion if the COMP_POL bit is set to '0'.
