Analog to Digital Converters

ADS1120IPW Description

The ADS1120IPW from Texas Instruments is a high-precision, 16-bit, delta-sigma analog-to-digital converter (ADC) designed for low-power, high-accuracy measurement applications. Housed in a compact 16-TSSOP package, it integrates a programmable gain amplifier (PGA) and a temperature sensor, making it ideal for sensor interfaces in industrial, medical, and consumer electronics. With a 2kSPS sampling rate, it supports both differential and single-ended inputs (2 or 4 channels) and operates from a 2.3V to 5.5V dual supply (analog/digital). Its SPI interface ensures seamless communication with microcontrollers, while its internal/external reference options enhance flexibility.

ADS1120IPW Features

• 16-bit resolution with low noise PGA (up to 128x gain) for precise signal conditioning.
• Integrated temperature sensor for system diagnostics or cold-junction compensation in thermocouples.
• Flexible power options: Single-supply operation (2.3V–5.5V) with 1mW power consumption at 2kSPS.
• Multi-input support: 2 or 4 channels configurable as differential/single-ended.
• Robust design: ROHS3 compliant, MSL 2 (1 year) moisture sensitivity, and REACH unaffected.
• On-chip features: Burnout current sources, oscillator, and voltage reference (2.048V or internal supply-derived).

ADS1120IPW Applications

• Industrial sensors: Strain gauges, RTDs, and pressure transducers benefit from its high accuracy and PGA.
• Medical devices: Portable monitors (ECG, blood glucose) leverage its low power and noise performance.
• Automotive systems: Battery management (BMS) and temperature sensing due to its wide supply range.
• Consumer electronics: Smart scales, HVAC controls, and IoT edge nodes.
• Thermocouple interfaces: Cold-junction compensation via the integrated temperature sensor.

Conclusion of ADS1120IPW

The ADS1120IPW stands out for its integration (PGA, temp sensor, reference), low-power operation, and versatile input configurations, reducing external component count. Its 16-bit resolution and 2kSPS rate strike a balance between speed and precision, ideal for cost-sensitive, space-constrained designs. Compared to similar ADCs, it excels in sensor-heavy applications requiring minimal calibration. A reliable choice for engineers seeking a compact, feature-rich ADC for precision measurement systems.
