The ADS1146/7/8 feature an • Single-Cycle Settling for All Data Rates onboard, low-noise, programmable gain amplifier • Simultaneous 50/60Hz Rejection at 20SPS (PGA), a precision delta-sigma ADC with a • 4 Differential/7 Single-Ended Inputs (ADS1148) single-cycle settling digital filter, and an internal oscillator. The ADS1147 and ADS1148 also provide a • 2 Differential/3 Single-Ended Inputs (ADS1147) built-in voltage reference with 10mA output capacity, • Matched Current Source DACs and two matched programmable current • Internal Voltage Reference digital-to-analog converters (DACs). The ADS1146/7/8 provide a complete front-end solution • Sensor Burnout Detection for temperature sensor applications including thermal • 4/8 General-Purpose I/Os (ADS1147/8) couples, thermistors, and resistance temperature • Internal Temperature Sensor detectors (RTDs). • Power Supply and VREF Monitoring An input multiplexer supports four differential inputs (ADS1147/8) for the ADS1148, two for the ADS1147, and one for the ADS1146. In addition, the multiplexer has a • Self and System Calibration sensor burnout detect, voltage bias for • SPI™-Compatible Serial Interface thermocouples, system monitoring, and • Analog Supply Operation: general-purpose digital I/Os (ADS1147 and +2.7V to +5.25V Unipolar, ±2.5V Bipolar ADS1148). The onboard, low-noise PGA provides selectable gains of 1 to 128. The delta-sigma • Digital Supply: +2.7V to +5.25V modulator and adjustable digital filter settle in only • Operating Temperature –40°C to +125°C one cycle, for fast channel cycling when using the input multiplexer, and support data rates up to APPLICATIONS 2kSPS. For data rates of 20SPS or less, both 50Hz • Temperature Measurement and 60Hz interference are rejected by the filter. – RTDs, Thermocouples, and Thermistors The ADS1146 is offered in a small TSSOP-16 • Pressure Measurement package, the ADS1147 is available in a TSSOP-20 • Industrial Process Control package, and the ADS1148 in a TSSOP-28 package. All three devices operate over the extended specified temperature range of –40°C to +105°C. 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 SPI is a trademark of Motorola, Inc. 3 All other trademarks are the property of their respective owners.
