Automotive 12-Bit 3.3kSPS 1-Ch Delta-Sigma ADC With PGA, Oscillator, VREF, Comparator, and I2C

The ADS1013-Q1, ADS1014-Q1, and ADS1015-Q1 ( ADS101x-Q1) are precision, low-power, 12-bit,

I 2C-compatible, analog-to-digital converters (ADCs) offered in VSSOP-10

and UQFN-10 packages. The ADS101x-Q1 incorporate a low-drift voltage

reference and an oscillator. The ADS1014-Q1 and ADS1015-Q1 also incorporate a

programmable gain amplifier (PGA) and a digital comparator. These features, along

with a wide operating supply range, are useful for power- and space-constrained,

sensor measurement applications.

The ADS101x-Q1 perform conversions

at data rates up to 3300 samples per second (SPS). The PGA offers input ranges from

±256 mV to ±6.144 V, allowing precise large- and small-signal measurements. The

ADS1015-Q1 features an input multiplexer (MUX) that allows two differential or four

single-ended input measurements. Use the digital comparator in the ADS1014-Q1 and

ADS1015-Q1 for under- and overvoltage detection.
