The ADS1000-Q1 is an I2C-compatible serial interface
analog-to-digital (A/D) converter with differential inputs and 12 bits of resolution in a tiny
SOT23-6 package. Conversions are performed ratiometrically, using the power supply as the reference
voltage. The ADS1000-Q1 operates from a single power supply ranging from 2.7 V to 5.5 V.
The ADS1000-Q1 performs conversions at a rate of 128 samples per second (SPS). The
onboard programmable gain amplifier (PGA), which offers gains of up to 8, allows smaller signals to
be measured with high resolution. In single-conversion mode, the ADS1000-Q1 automatically powers
down after a conversion, greatly reducing current consumption during idle periods.
The ADS1000-Q1 is designed for applications where space and power consumption are major
considerations. Typical applications include head units, battery management systems, on-board
chargers, and emissions and gas sensors.
