ADS1119IPWT

Analog To Digital Converters (ADC) Overview

The ADS1119IPWT is a 16-bit analog-to-digital converter (ADC) from Texas Instruments, housed in a 16-TSSOP package. It features a sigma-delta architecture with an integrated multiplexer supporting four differential or single-ended inputs. The device operates on a single supply voltage ranging from 2.3V to 5.5V for both analog and digital domains. It supports sampling rates up to 1kSPS and communicates via an I2C-compatible serial interface. The component includes a programmable gain amplifier and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated four-channel multiplexer enabling flexible input configuration for differential or single-ended signals.
• Sigma-delta modulation architecture provides high resolution with internal filtering capabilities.
• Supports standard I2C serial interface for simplified system connectivity and data transfer.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Portable instrumentation utilizing low-voltage power supplies
• Data acquisition modules for environmental monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number including the suffix to confirm the specific tape and reel packaging configuration intended for your assembly line. Confirm that the RoHS status aligns with current regulatory requirements for your target market. Ensure compatibility with your existing I2C bus voltage levels given the wide operating supply range. Check for any recent product change notifications regarding marking or material composition updates.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate speed and high resolution is required for multiple input channels. The integrated PGA reduces external component count compared to non-PGA alternatives. Consider the TSSOP package dimensions against available PCB space constraints. Evaluate the 1kSPS maximum rate against your Nyquist requirements for the specific signal bandwidth being measured.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS111x family of precision ADCs designed for general-purpose applications. It shares architectural similarities with other members like the ADS1110 but offers additional channel flexibility through its internal multiplexer. The IPWT suffix indicates a specific thermal and mechanical variant within the broader ADS1119 product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-to-pin replacements within the same family include the ADS1118IPWT, which offers fewer channels but similar performance characteristics. Verify functional equivalence regarding register maps and timing specifications before substitution. Cross-model comparisons should focus on channel count and interface compatibility rather than just resolution.
