Overview
The ADS1286PAG4 is a 12-bit micro-power sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with a single differential input channel. The device operates on dual power supplies ranging from 4.5 V to 5.25 V for both analog and digital domains. It supports serial interfaces including SPI, I2C, and 3-wire communication. The component is specified for an operating temperature range of -40°C to +85°C and is housed in a 14-pin TSSOP package.
Feature Summary
- Micro-power consumption suitable for battery-operated systems
- Integrated SAR ADC with high-speed sampling capabilities
- Flexible digital interface supporting multiple serial protocols
Applications
- Portable medical instrumentation
- Industrial process control data acquisition
- Battery-powered sensor nodes
Procurement Notes
Verify the specific suffix 'PAG4' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering part number matches the required tape-and-reel or tube packaging configuration for your assembly line. Cross-reference the date code to ensure availability of fresh stock for sensitive applications.
Selection Notes
Select this component when a balance between moderate resolution and low power consumption is required. It is appropriate for applications needing single-channel conversion without the complexity of multi-channel multiplexing. Consider thermal management requirements if operating near the upper limit of the specified temperature range.
Part Context
This part belongs to the ADS1286 family of micro-power ADCs. It shares architectural similarities with other devices in the series but differs in package type and specific interface configurations. The PAG4 designation indicates a specific lead-free and RoHS-compliant variant within the broader product line.
Replacement Considerations
Direct substitutes include ADS1286UCG4 and ADS1286UA. Verify pin compatibility and software register settings before swapping. Alternative families may require schematic modifications due to differences in interface timing or power supply requirements.
