产品信息
描述 The ADS1113-Q1, ADS1114-Q1, and ADS1115-Q1 devices (ADS111x-Q1) are precision, low-power, 16-bit, I2C-compatible, analog-to-digital converters (ADCs) offered in a VSSOP-10 package. The ADS111x-Q1 devices incorporate a low-drift voltage reference and an oscillator. The ADS1114-Q1 and ADS1115-Q1 also incorporate a programmable gain amplifier (PGA) and a digital comparator. These features, along with a wide operating supply range, make the ADS111x-Q1 well suited for power- and space-constrained, sensor measurement applications. The ADS111x-Q1 perform conversions at data rates up to 860 samples per second (SPS). The PGA offers input ranges from ±256 mV to ±6.144 V, allowing precise large- and small-signal measurements. The ADS1115-Q1 features an input multiplexer (MUX) that allows two differential or four single-ended input measurements. Use the digital comparator in the ADS1114-Q1 and ADS1115-Q1 for under- and overvoltage detection.The ADS111x-Q1 operate in either continuous-conversion mode or single-shot mode. The devices are automatically powered down after one conversion in single-shot mode; therefore, power consumption is significantly reduced during idle periods.特性Qualified for Automotive Applications AEC-Q100 Qualified With the Following Results: Temperature Grade 1: –40°C to +125°C HBM ESD Classification 2 CDM ESD Classification C4B Wide Supply Range: 2.0 V to 5.5 V Low Current Consumption: 150 µA (Continuous-Conversion Mode) Programmable Data Rate: 8 SPS to 860 SPS Single-Cycle Settling Internal Low-Drift Voltage Reference Internal Oscillator I2C Interface: Four Pin-Selectable Addresses Four Single-Ended or Two Differential Inputs (ADS1115-Q1) Programmable Comparator (ADS1114-Q1 and ADS1115-Q1)
