The ADS1100A0IDBVR is a self-calibrating, 16-bit delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. Housed in a tiny SOT-23-6 package, it integrates a programmable gain amplifier (PGA) and an I2C interface, providing a complete data acquisition system in minimal board space. With its low power consumption of only 90\u00b5A and wide supply range of 2.7V to 5.5V, it is ideal for portable and battery-powered instrumentation.<\/p>\n

It performs ratiometric conversions using the power supply as reference voltage, eliminating the need for an external reference. The device features continuous self-calibration, ensuring drift-free performance over time and temperature. With PGA gains of 1, 2, 4, or 8, the ADS1100 can measure small differential signals with high resolution. Data rates are programmable from 8 SPS to 128 SPS. In single-conversion mode, the ADC automatically powers down after each conversion, reducing idle current to mere microamps. The I2C interface supports standard (100kHz), fast (400kHz), and high-speed (3.4MHz) modes. Eight pin-selectable I2C addresses allow multiple ADS1100 devices on the same bus.","working_principle":"The ADS1100 employs a second-order delta-sigma modulator followed by a digital decimation filter. The modulator oversamples the input at a frequency much higher than the output data rate, converting the analog input into a high-speed bit stream. The digital filter then decimates this bit stream to produce 16-bit output data. The on-chip PGA amplifies small differential signals before the modulator, enabling measurement of millivolt-level inputs. Self-calibration runs continuously in the background, compensating for offset and gain drift. The configuration register controls data rate, PGA gain, and conversion mode (single or continuous). In single-conversion mode, the ST\/BSY bit initiates a conversion and indicates when results are ready.","pin_description":"

      • Portable Instrumentation:<\/b> The ADS1100's 90\u00b5A operating current and SOT-23-6 footprint make it ideal for handheld multimeters and DMMs. Use PGA gain of 8 to measure millivolt-level signals from shunt resistors or thermocouples directly, with 16-bit resolution providing 1\u00b5V LSB at gain 8.<\/li>
      • Industrial Process Control:<\/b> In 4-20mA current loop receivers, the ADS1100 digitizes the voltage across a precision shunt resistor. The differential input rejects common-mode noise, while self-calibration maintains long-term accuracy without periodic recalibration. Multiple devices can share the I2C bus using different addresses.<\/li>
      • Battery-Powered Data Loggers:<\/b> Single-conversion mode powers down the ADC between readings, extending battery life. At 8 SPS with gain 1, the ADS1100 achieves maximum resolution while consuming minimal energy per measurement cycle.<\/li><\/ul>","alternative_models":"
