Ultra-Small, Low-Power, 16-Bit

Analog-to-Digital Converter with Internal Reference

Check for Samples: ADS1113 ADS1114 ADS1115

FEATURES

DESCRIPTION

•

ULTRA-SMALL QFN PACKAGE:

2mm × 1,5mm × 0,4mm

The ADS1113, ADS1114, and ADS1115 are

precision analog-to-digital converters (ADCs) with 16

bits of resolution offered in an ultra-small, leadless

QFN-10 package or an MSOP-10 package. The

ADS1113/4/5 are designed with precision, power, and

ease of implementation in mind. The ADS1113/4/5

feature an onboard reference and oscillator. Data are

transferred via an I²C-compatible serial interface; four

I²C slave addresses can be selected. The

ADS1113/4/5 operate from a single power supply

ranging from 2.0V to 5.5V.

•

WIDE SUPPLY RANGE: 2.0V to 5.5V

LOW CURRENT CONSUMPTION:

Continuous Mode: Only 150μA

Single-Shot Mode: Auto Shut-Down

•

PROGRAMMABLE DATA RATE:

8SPS to 860SPS

INTERNAL LOW-DRIFT

VOLTAGE REFERENCE

The ADS1113/4/5 can perform conversions at rates

up to 860 samples per second (SPS). An onboard

PGA is available on the ADS1114 and ADS1115 that

offers input ranges from the supply to as low as

±256mV, allowing both large and small signals to be

measured with high resolution. The ADS1115 also

features an input multiplexer (MUX) that provides two

differential or four single-ended inputs.

•

PROGRAMMABLE COMPARATOR

(ADS1114 and ADS1115)

The ADS1113/4/5 operate either in continuous

OPERATING TEMPERATURE: –40°C to +140°C

conversion mode or

single-shot mode that

automatically powers down after a conversion and

greatly reduces current consumption during idle

periods. The ADS1113/4/5 are specified from –40°C

to +125°C.
