ADS124S06, ADS124S08

SBAS660C –AUGUST 2016–REVISED JUNE 2017

ADS124S0x Low-Power, Low-Noise, Highly Integrated, 6- and 12-Channel,

4-kSPS, 24-Bit, Delta-Sigma ADC with PGA and Voltage Reference

1 Features

3 Description

The ADS124S06 and ADS124S08 are precision, 24-

bit, delta-sigma (ΔΣ), analog-to-digital converters

(ADCs) that offer low power consumption and many

integrated features to reduce system cost and

component count in applications measuring small-

signal sensors.

•

Low Power Consumption: As Low as 280 µA

Low-Noise PGA: 19 nV_RMSat Gain = 128

Programmable Gain: 1 to 128

•

Programmable Data Rates: 2.5 SPS to 4 kSPS

Simultaneous 50-Hz and 60-Hz Rejection at

≤ 20 SPS with Low-Latency Digital Filter

These ADCs feature configurable digital filters that

offer low-latency conversion results and 50-Hz or

60-Hz rejection for noisy industrial environments. A

low-noise, programmable gain amplifier (PGA)

provides gains ranging from 1 to 128 to amplify low-

level signals for resistive bridge or thermocouple

applications. Additionally, these devices integrate a

low-drift, 2.5-V reference that reduces printed circuit

board (PCB) area. Finally, two programmable

excitation current sources (IDACs) allow for easy and

accurate RTD biasing.

•

Analog Multiplexer with 12 (ADS124S08) or 6

(ADS124S06) Independently Selectable Inputs

Dual-Matched Programmable Current Sources for

Sensor Excitation: 10 µA to 2000 µA

•

Internal Reference: 2.5 V, 10 ppm/°C (max) Drift

Internal Oscillator: 4.096 MHz, 1.5% Accuracy

Internal Temperature Sensor

Extended Fault Detection Circuits

Self Offset and System Calibration

Four General-Purpose I/Os

An input multiplexer supports 12 inputs for the

ADS124S08 and six inputs for the ADS124S06 that

can be connected to the ADC in any combination for

design flexibility. In addition, these devices include

features such as sensor burn-out detection, voltage

bias for thermocouples, system monitoring, and four

general-purpose I/Os.

SPI-Compatible Interface with Optional CRC

Analog Supply: Unipolar (2.7 V to 5.25 V) or

Bipolar (±2.5 V)

•

Digital Supply: 2.7 V to 3.6 V

Operating Temperature: –50°C to +125°C

The devices are offered in a leadless VQFN-32 or a

TQFP-32 package.
