3 Description

The ADS1013-Q1, ADS1014-Q1, and ADS1015-Q1

(ADS101x-Q1) are precision, low-power, 12-bit,

I2C-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.
