3 Features

Several features that are available in the standard-grade devices are removed from the B-grade devices. Table 3-1 summarizes these features as well as their intended purpose in the standard-grade devices.

Table 3-1 Features Available Only in Standard-Grade Devices
FeaturePurpose
SINC3 FilterReduces ADC noise compared to low-latency filter, while increasing settling time
Low-Side Power SwitchPower-down path for resistive bridges to reduce power consumption between conversions
Global ChopAverages two readings to reduce offset, offset drift, and noise
PGA Rail DetectionDetects if the PGA is operating outside the linear region of operation
Reference Detection(1)Detects if the differential reference voltage drops below 1/3 × (AVDD – AVSS) V
Cyclic Redundancy Check (CRC)Detects single-bit or multibit data-transmission errors
Programmable Conversion DelayUser-defined programmable delay time to compensate for external analog circuitry settling time when multiplexing through channels
(1) A 300-mV reference detection threshold is available on both the standard and B-grade versions of the ADS114S0x
