TI intros 16-bit delta-sigma ADC for automotive market

DALLAS, USA: Texas Instruments Inc. (TI) introduced the industry's most highly integrated automotive-qualified, 16-bit delta-sigma analog-to-digital converter (ADC). The ADS1115-Q1 includes a reference, programmable gain amplifier (PGA), mux and oscillator in a small package and supports up to 860 samples per second (SPS).

For automotive applications such as battery monitoring systems in HEV/EV vehicles, fuel or oil pressure sensing, the ADS1115-Q1 offers the industry's only integrated programmable comparator, allowing easy over- or under-voltage threshold monitoring to increase design flexibility while reducing board space and component cost.

Key features and benefits of the ADS1115-Q1
On-chip integration increases design flexibility: Features an integrated oscillator, low-drift reference and 4-channel mux with PGA to support a wide range of inputs.

Low power extends battery life: Consumes only 150 uA of supply current at 2 V while running at up to 860 SPS.

High integration saves system space, component cost: Offers higher precision performance and component integration than the competition in a small, low-power, 16-bit solution for design efficiency and lower cost.

Extended ranges support automotive applications: Supports a wide supply range of 2 V to 5.5 V and operating temperature range of -40 Celsius (C) to 125 C, offering greater flexibility in system design.
