DESCRIPTION
The ADS1013, ADS1014, and ADS1015 are
precision analog-to-digital converters (ADCs) with 12
bits of resolution offered in an ultra-small, leadless
QFN-10 package or an MSOP-10 package. The
ADS1013/4/5 are designed with precision, power, and
ease of implementation in mind. The ADS1013/4/5
feature an onboard reference and oscillator. Data are
transferred via an I²C-compatible serial interface; four
I²C slave addresses can be selected. The
ADS1013/4/5 operate from a single power supply
ranging from 2.0V to 5.5V.
The ADS1013/4/5 can perform conversions at rates
up to 3300 samples per second (SPS). An onboard
PGA is available on the ADS1014 and ADS1015 that
offers input ranges from the supply to as low as
±256mV, allowing both large and small signals to be
measured with high resolution. The ADS1015 also
features an input multiplexer (MUX) that provides two
differential or four single-ended inputs.
The ADS1013/4/5 operate either in continuous
conversion mode or a single-shot mode that
automatically powers down after a conversion and
greatly reduces current consumption during idle
periods. The ADS1013/4/5 are specified from –40°C
to +125°C.
