具有振荡器、电压基准和 I2C 的汽车类 16 位 860SPS 单通道 Δ-Σ ADC 10-VSSOP -40 to 125
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.
