ADS111x/ADS111x-Q1 16-Bit Delta-Sigma ADCs Texas Instruments ADS111x/ADS111x-Q1 16-Bit Delta-Sigma Analog-to-Digital Converters (ADCs) are precision, low-power, I2C-compatible ADCs offered in a VSSOP-10 package and an ultra-small, leadless, X2QFN-10 package. The ADS111x/ADS111x-Q1 devices incorporate a low-drift voltage reference and an oscillator. The ADS1114/ADS1114-Q1 and ADS1115/ADS1115-Q1 also include a programmable gain amplifier (PGA) and a digital comparator. These features and a wide operating supply range make the ADS111x/ADS111x-Q1 well-suited for power- and space-constrained sensor measurement applications.
