ADS1119IPW

Analog To Digital Converters (ADC) Overview

The ADS1119IPW is a 16-bit, low-power analog-to-digital converter (ADC) from Texas Instruments. It features four differential or single-ended inputs and utilizes a sigma-delta architecture with an internal programmable gain amplifier (PGA). The device operates on a single supply voltage ranging from 2.3 V to 5.5 V for both analog and digital domains. It supports a maximum sampling rate of 1 kSPS and communicates via an I2C-compatible serial interface. The component is housed in a 16-pin TSSOP package and is rated for operation within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPW indicates tube packaging when ordering. Confirm the manufacturer is Texas Instruments to ensure authenticity. Check RoHS compliance status as per current datasheet revisions. Ensure the I2C address configuration matches the system design requirements before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring high resolution with moderate speed. The 16-bit resolution provides detailed signal capture. The wide operating voltage range allows flexibility in power supply design. Consider the TSSOP-16 package constraints for PCB layout. Verify thermal performance within the specified industrial temperature limits.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS111x series of precision ADCs. It shares architectural similarities with other members like the ADS1118 but offers four channels instead of one. The IPW suffix distinguishes it from tape-and-reel variants such as the IPWR. It serves as a general-purpose solution for multi-channel sensing tasks.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1119IPWR is a direct pin-compatible alternative differing only in packaging format. Other family members like the ADS1118 offer similar functionality with fewer channels. Cross-reference datasheets for any minor electrical parameter differences between variants.
