Texas Instruments introduces a pair of 32-bit delta-sigma analog-to-digital converters (ADCs) that combine high resolution, low noise, and integrated fault detection capabilities, eliminating many of the performance and functional compromises typically associated with them Evaluation and selection. The highly integrated sensor-ready ADS1262 and ADS1263 also eliminate the need for external components that increase system cost and reduce noise and drift performance.
Until now, system designers who need high-resolution ADCs have had to sacrifice other required specifications, such as low noise or low offset drift, and some integrated features. The ADS1262 and ADS1263 eliminate these trade-offs by providing 32-bit resolution, integration, fault detection capabilities, fast data rates, and a wide temperature range, thereby helping to maximize the performance and performance of programmable logic controllers (PLCs) and industrial automation equipment. Sensor measurement applications.
Key Features: 1-Accurate measurement of small signals: At 2.5 SPS, high resolution of 32 bits and low noise of 7 nVRMS enable measurement of the smallest signal, which is 10 mV or less for a typical full-scale signal Bridge applications are critical. Offset error drift is also 80% lower than competing solutions, ensuring measurement stability over temperature. 2-Reduced component count, thus reducing system cost, board area and design time: ADS1262 integrates a programmable gain amplifier (PGA), 2. 5V reference voltage, oscillator, level shifter, temperature sensor, dual excitation current source (IDAC) and eight general-purpose input / output (GPIO) pins. The ADS1263 adds a secondary 24-bit delta-sigma ADC for systems that require parallel main channel conversion, sensor temperature compensation, or sensor diagnostics. 3-Integrated monitoring and diagnostics: Internal signal chain monitoring, data error detection, sensor disconnection detection and test digital-to-analog converter (DAC) functions provide internal and external fault detection and diagnostics for high reliability. Reliability system.
