Texas Instruments' ADS1115-Q1 is the industry's most highly integrated automotive-qualified 16-bit delta-sigma analog-to-digital converter (ADC), claims the company. Supporting up to 860 samples per second, the device includes a reference, programmable gain amplifier, mux, and oscillator in a small package. For automotive applications such as battery monitoring systems in HEV/EV vehicles and fuel or oil pressure sensing, the ADS1115-Q1 offers the industry’s only integrated programmable comparator, claims TI, allowing easy over- or under-voltage threshold monitoring to increase design flexibility while reducing board space and component cost. Key features of the ADS1115-Q1 are on-chip integration to increase design flexibility, low power to extend battery life, high integration to save system space and component cost, and extended ranges to support automotive applications.
