ADS1115BQDGSRQ1

The ADS1113-Q1, ADS1114-Q1, and ADS1115-Q1 devices (ADS111x-Q1) are 16-bit, low-power, precision analog-to-digital converters (ADCs) with I2C compatibility, packaged in VSSOP-10 and UQFN-10. The ADS111x-Q1 devices feature a low-drift voltage reference and an oscillator. The ADS1114-Q1 and ADS1115-Q1 also include a programmable gain amplifier (PGA) and a digital comparator. In addition to these features, the ADS111x-Q1 has a wide operating supply voltage range, making it well-suited for power- and space-constrained sensor measurement applications. The ADS111x-Q1 can perform conversions at data rates of up to 860 samples per second (SPS). The PGA provides input ranges from ±256mV to ±6.144V, enabling accurate measurement of both large and small signals. The ADS1115-Q1 has an input multiplexer (MUX) that allows for dual differential or quad single-ended input measurements. The digital comparator in the ADS1114-Q1 and ADS1115-Q1 can be used for undervoltage and overvoltage detection.
