ADS1112 Description

Short technical summary and product information.

The ADS1112 from Texas Instruments is a high-precision, 16-bit Analog-to-Digital Converter (ADC) designed for a variety of data acquisition applications. It utilizes a Delta-Sigma architecture and supports both differential and single-ended input types, with multiplexed channel configurations allowing for measurements from up to two differential or three single-ended channels.

 

Key electrical features include a programmable data rate ranging from 15SPS to 240SPS, an onboard oscillator, and a programmable gain amplifier (PGA). The device operates with analog and digital supply voltages between 2.7V and 5.5V, consuming a typical power of 0.675mW. It also features an internal, pin-selectable voltage reference with an accuracy of 2.048V ±0.05% and a low drift of 5ppm/°C.

 

Available in compact VSON (DRC) and VSSOP (DGS) packages, the ADS1112 is suitable for space-constrained designs. Its operating temperature range is -40°C to 85°C, making it robust for industrial process control, portable instrumentation, and factory automation.

 

The I2C interface supports eight selectable addresses, simplifying integration into existing systems. The ADC boasts 16-bit resolution with no missing codes and a maximum Integral Non-Linearity (INL) of 0.01% of FSR, ensuring accurate measurements.
