ADS1224IPWR

Overview

The ADS1224IPWR is a low-power, 24-bit analog-to-digital converter (ADC) from Texas Instruments, housed in a TSSOP-20 package. It features a sigma-delta architecture with four differential or single-ended input channels and an SPI interface. The device supports sampling rates up to 240 S/s and operates on analog and digital supply voltages ranging from 2.7 V to 5.5 V. Key performance metrics include a differential nonlinearity of +/- 1 LSB and integral nonlinearity of 0.0015% FSR. Power consumption is rated at 1.35 mW typical and 2.25 mW maximum. It includes built-in 50/60 Hz rejection and a temperature sensor, functioning within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated multiplexer and programmable gain amplifier for flexible signal conditioning
• Built-in internal oscillator and external clock options for precise timing control
• On-chip temperature sensor for system monitoring capabilities

Applications

• Industrial process control systems requiring high-resolution data acquisition
• Portable battery-powered instrumentation due to low power consumption
• Weight scales and load cell measurement applications

Procurement Notes

Verify the specific suffix against official documentation to confirm pin compatibility and electrical characteristics. Ensure the component meets RoHS standards if required by your manufacturing process. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent package damage during production.

Selection Notes

Select this model when four independent channels are necessary for simultaneous multi-sensor monitoring. Compare against the ADS1222 for two-channel requirements or the ADS122C04 for I2C interface compatibility. Consider the ADS1242 if higher channel counts or different sampling speeds are needed for the target application design.

Part Context

This component belongs to the ADS122x family of precision ADCs designed for cost-sensitive, space-constrained applications. It shares architectural similarities with other members like the ADS1220 and ADS1222 but offers four input channels. The IPWR suffix indicates a plastic small-outline package suitable for surface-mount technology in compact electronic designs.

Replacement Considerations

ADS1224IPWT is a tape-and-reel variant of the same functional device. ADS1224IPWRG4 denotes a lead-free version compliant with specific environmental directives.
