12-Bit 3.3kSPS 1-Ch Delta-Sigma ADC With Oscillator, Voltage Reference, and I2C

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

I2C-compatible, analog-to-digital converters (ADCs) offered in a leadless X2QFN-10, a

SOT-10, and a VSSOP-10 package. The ADS101x incorporates a

low-drift voltage reference and an oscillator. The ADS1014 and ADS1015 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 perform

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

ranges from ±256mV to ±6.144V, allowing precise large- and small-signal

measurements. The ADS1015 features an input multiplexer (MUX) that allows two

differential or four single-ended input measurements. Use the digital comparator in

the ADS1014 and ADS1015 for under- and overvoltage detection.
