Overview
The ADS1250UG4 is a 24-bit analog-to-digital converter (ADC) from Texas Instruments, utilizing sigma-delta architecture. It features a single differential input channel and supports SPI communication interfaces. The device operates with both analog and digital supply voltages ranging from 4.75 V to 5.25 V. It achieves a sampling rate of 20 kS/s and includes built-in 50/60 Hz rejection capabilities. The component is housed in an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- High-resolution 24-bit data acquisition capability
- Integrated programmable gain amplifier for signal conditioning
- Low power consumption suitable for battery-operated systems
Applications
- Industrial process control systems
- Weighing scales and load cell measurements
- Medical equipment requiring high precision
Procurement Notes
Verify the specific suffix 'UG4' indicates RoHS compliance and lead-free manufacturing status as per Texas Instruments documentation. Confirm the package type matches the design requirements before ordering. Ensure the external reference voltage meets the specified operating conditions for optimal performance.
Selection Notes
Select this component when a single-channel, high-precision measurement solution is required. The ADS1250UG4 is appropriate for applications needing low noise and high linearity at moderate data rates. Consider the external reference requirement and available PCB space for the SOIC-8 package during the design phase.
Part Context
This part belongs to the ADS125x family of low-power, high-precision ADCs from Texas Instruments. These devices are designed for demanding industrial and scientific applications where accuracy and low power are critical. The UG4 variant specifically denotes the commercial grade version in an SOIC package with enhanced environmental compliance.
Replacement Considerations
Direct pin-compatible alternatives within the same family include the ADS1251U and ADS1252U, which offer similar performance characteristics with potential differences in channel count or interface options.
