ADS1015 ADS1015 ADS1013 ADS1014 ADS1015 www.ti.com SBAS473C MAY 2009REVISED OCTOBER 2009 Ultra-Small, Low-Power, 12-Bit Analog-to-Digital Converter with Internal Reference Check for Samples: ADS1013 ADS1014 ADS1015 1 FEATURES DESCRIPTION 23 ULTRA-SMALL QFN PACKAGE: The ADS1013, ADS1014, and ADS1015 are 2mm 1,5mm 0,4mm precision analog-to-digital converters (ADCs) with 12 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: ADS1013/4/5 are designed with precision, power, and Continuous Mode: Only 150A ease of implementation in mind. The ADS1013/4/5 Single-Shot Mode: Auto Shut-Down feature an onboard reference and oscillator. Data are 2 PROGRAMMABLE DATA RATE: transferred via an I C-compatible serial interface four 2 128SPS to 3.3kSPS I C slave addresses can be selected. The ADS1013/4/5 operate from a single power supply INTERNAL LOW-DRIFT ranging from 2.0V to 5.5V. VOLTAGE REFERENCE The ADS1013/4/5 can perform conversions at rates INTERNAL OSCILLATOR up to 3300 samples per second (SPS). An onboard INTERNAL PGA PGA is available on the ADS1014 and ADS1015 that 2 I C 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 ADS1015 also DIFFERENTIAL INPUTS (ADS1015) features an input multiplexer (MUX) that provides two PROGRAMMABLE COMPARATOR differential or four single-ended inputs. (ADS1014 and ADS1015) The ADS1013/4/5 operate either in continuous conversion mode or a single-shot mode that APPLICATIONS automatically powers down after a conversion and PORTABLE INSTRUMENTATION greatly reduces current consumption during idle CONSUMER GOODS periods. The ADS1013/4/5 are specified from 40C BATTERY MONITORING to +125C.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
