SGM58031 Ultra-Small, Low-Power, 16-Bit Analog-to-Digital Converter with Internal Reference GENERAL DESCRIPTION The SGM58031 is precision analog-to-digital converter (ADC) with 16 bits of resolution. The SGM58031 is designed with precision, low power, and ease of implementation. The SGM58031 features an on-chip reference and oscillator. Data are transferred via an I2C-compatible serial interface; four I2C slave addresses can be selected. The SGM58031 operates from a single power supply ranging from 3V to 5.5V. The SGM58031 can perform conversions at rates up to 960 samples per second (SPS). An on-chip PGA is available on the SGM58031 that offers input ranges from the supply to as low as ±256mV, allowing both large and small signals to be measured with high resolution. The SGM58031 also features an input multiplexer (MUX) that provides two differential or four single-ended inputs. The SGM58031 operates either in continuous conversion mode or a single-shot mode that automatically powers down after a conversion and greatly reduces current consumption during idle periods. The SGM58031 is available in Green MSOP-10 and TDFN-3×3-10L packages and it is specified from -40℃ to +125℃. FEATURES ● Wide Power Supply Range: 3V to 5.5V  I2C Bus Voltage: 3V to 5.5V ● Low Current Consumption: Continuous Mode: 255μA (TYP) Power-Down Mode: 0.8μA (TYP) ● Programmable Date Rate: 6.25SPS to 960SPS ● Internal Low-Drift Voltage Reference ● Internal Oscillator ● Internal PGA ● I2C Interface: Pin-Selectable Addresses ● Four Single-Ended or Two Differential Inputs ● Programmable Comparator ● Available in Green MSOP-10 and TDFN-3×3-10L Packages APPLICATIONS Portable Instrumentation Consumer Goods Battery Monitoring Temperature Measurement Factory Automation and Process Controls SG Micro Corp www.sg-micro.com DECEMBER 2019 – REV.

SGMICRO 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.

This parameter expresses the full-scale range of the ADC scaling. In no event should more than VDD + 0.3V be applied to this device. 2. 99% of full-scale. 3. Includes all errors from on-chip PGA and reference. 4. Gain temperature drift is defined as the maximum change of gain error measured over the specified temperature range. The gain error drift is calculated using the box method, as described by Equation: Gain Error Drift = (GEMAX - GEMIN)/(TMAX - TMIN) where: • GEMAX and GEMIN are the maximum and minimum gain errors, respectively. • TMAX and TMIN are the maximum and minimum temperatures, respectively, over the temperature range -40℃ to +125℃.

There are 2 scenarios: VDD = 5V, VBUS can be 3V to 5V; VDD = 3.3V, VBUS should be 3.3V. Note that VBUS = 3V may cause leakage in some extreme conditions, and it's better to make it higher than 3.1V. For VBUS = VDD, VIL/VIH = 30%/70% of VBUS. For VBUS = 3.3V and VDD = 5V, VIL/VIH = 20%/80% of VBUS. 6. Meet the "loss of VDD" requirement of I2C fast mode. When VDD is lost, the leakage drawn from the pin is controlled. 7. Power-down current increases to 2.3μA at +25℃ and 3.5μA at +125℃ when Config1 BUS_FLEX is set to '1'.
