ADS1013

The Texas Instruments ADS1013 is a high-precision, 12-bit Analog-to-Digital Converter (ADC) designed for efficient data acquisition. Operating with a sample rate of up to 3.3kSPS, this delta-sigma ADC offers a single input channel that can be configured for single-ended or differential measurements.

Key electrical features include a wide analog and digital supply voltage range from 2.0V to 5.5V, and a low power consumption of typically 0.3mW. The device incorporates an internal low-drift voltage reference and an internal oscillator, simplifying external component requirements. Communication is handled via an I2C interface, supporting four pin-selectable addresses.

The ADS1013 is available in ultra-small packages such as X2QFN (1.5mm x 2mm) and SOT (2.9mm x 2.8mm), making it ideal for space-constrained designs. Its operating temperature range is -40°C to +125°C, ensuring reliable performance in demanding environments.

This ADC is part of the ADS101x family, which includes variants with additional features like comparators and programmable gain amplifiers (PGAs). The ADS1013 itself is well-suited for applications requiring accurate analog-to-digital conversion where low power and small size are critical.
