ADS1014QNKSRQ1

Analog To Digital Converters (ADC) Overview

The ADS1014QNKSRQ1 is a precision, automotive-grade analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 12-bit resolution and utilizes a sigma-delta architecture to achieve a maximum data rate of 3.3 kSPS. The device supports both differential and single-ended input configurations through an integrated multiplexer. It operates with a supply voltage range of 2V to 5.5V for both analog and digital domains. Communication is handled via an I2C-compatible serial interface. The component is qualified under AEC-Q100 standards and functions within a temperature range of -40°C to +125°C.
