SBAS444A – MAY 2009 – REVISED AUGUST 2009 Ultra-Small, Low-Power, 16-Bit Analog-to-Digital Converter with Internal Reference Check for Samples: ADS1113 ADS1114 ADS1115 1 FEATURES DESCRIPTION 23 • ULTRA-SMALL QFN PACKAGE: The ADS1113, ADS1114, and ADS1115 are 2mm × 1,5mm × 0,4mm precision analog-to-digital converters (ADCs) with 16 bits of resolution offered in an ultra-small, leadless • WIDE SUPPLY RANGE: 2.0V to 5.5V QFN-10 package or an MSOP-10 package. The • LOW CURRENT CONSUMPTION: ADS1113/4/5 are designed with precision, power, and Continuous Mode: Only 150 μA ease of implementation in mind. The ADS1113/4/5 Single-Shot Mode: Auto Shut-Down feature an onboard reference and oscillator. Data are • PROGRAMMABLE DATA RATE: transferred via an I2C-compatible serial interface; four I2C slave addresses can be selected. The 8SPS to 860SPS ADS1113/4/5 operate from a single power supply • INTERNAL LOW-DRIFT ranging from 2.0V to 5.5V. VOLTAGE REFERENCE The ADS1113/4/5 can perform conversions at rates • INTERNAL OSCILLATOR up to 860 samples per second (SPS). An onboard • INTERNAL PGA PGA is available on the ADS1114 and ADS1115 that • I2C ™ INTERFACE: Pin-Selectable Addresses offers input ranges from the supply to as low as ±256mV, allowing both large and small signals to be • FOUR SINGLE-ENDED OR TWO measured with high resolution. The ADS1115 also DIFFERENTIAL INPUTS (ADS1115) features an input multiplexer (MUX) that provides two • PROGRAMMABLE COMPARATOR differential or four single-ended inputs. (ADS1114 and ADS1115) The ADS1113/4/5 operate either in continuous • OPERATING TEMPERATURE: –40°C to +140°C conversion mode or a single-shot mode that automatically powers down after a conversion and APPLICATIONS greatly reduces current consumption during idle • PORTABLE INSTRUMENTATION periods. The ADS1113/4/5 are specified from –40°C to +125°C. • CONSUMER GOODS • BATTERY MONITORING • TEMPERATURE MEASUREMENT • FACTORY AUTOMATION AND PROCESS CONTROLS 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 I2C is a trademark of NXP Semiconductors. 3 All other trademarks are the property of their respective owners.
