ADS1115IDGSR

Texas Instruments ADS1115IDGSR - High-Precision 16-Bit Analog-to-Digital Converter

The ADS1115IDGSR from Texas Instruments is a precision 16-bit analog-to-digital converter featuring an integrated programmable gain amplifier (PGA), voltage reference, and oscillator. With its I2C-compatible serial interface and four multiplexed input channels, this ultra-small, low-power ADC is ideal for space-constrained, power-sensitive sensor measurement applications. The device can perform conversions at data rates up to 860 samples per second (SPS) with exceptional accuracy and low noise.

Key Features:

• High Resolution: 16-bit sigma-delta ADC for precise measurements
• Flexible Input Configuration: 4 single-ended or 2 differential inputs with integrated multiplexer
• Programmable Gain Amplifier: PGA with gains from ±256mV to ±6.144V full-scale range
• Fast Sampling Rate: Up to 860 samples per second for responsive measurements
• I2C Interface: Simple 2-wire digital interface with 4 selectable addresses
• Internal Voltage Reference: Eliminates need for external reference components
• Low Power Consumption: Ideal for battery-powered and portable applications
• Wide Supply Range: 2V to 5.5V operation for both analog and digital supplies
• Extended Temperature Range: -40°C to 125°C for industrial environments
• Compact Package: 10-VSSOP surface mount package saves valuable board space

Applications:

The ADS1115IDGSR is perfectly suited for a wide range of precision measurement applications including:

• Portable instrumentation and handheld test equipment
• Industrial process control and factory automation
• Temperature, pressure, and humidity sensor interfaces
• Battery monitoring and power management systems
• Medical and healthcare monitoring devices
• Consumer electronics and smart home devices
• Data acquisition systems and data loggers
• Weigh scales and load cell signal conditioning
• Bridge sensor amplification (strain gauges, pressure sensors)
• Multi-channel sensor monitoring systems

Design Advantages:

The integrated MUX-PGA-ADC configuration of the ADS1115IDGSR significantly reduces external component count and board space requirements. The programmable gain amplifier allows direct interfacing to sensors with varying output ranges without external signal conditioning circuitry. The I2C interface with four selectable addresses enables multiple devices on a single bus, making it ideal for multi-channel measurement systems. The sigma-delta architecture provides excellent noise rejection and linearity, ensuring accurate measurements even in electrically noisy environments.
