ADS1158IRTCTG4

Analog To Digital Converters (ADC) Overview

The ADS1158IRTCTG4 is a 16-channel, 16-bit Analog-to-Digital Converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture to achieve high precision data conversion. The device supports a sampling rate of up to 860 kSPS and operates with an analog supply voltage range of 2.7 V to 5.5 V and a digital supply voltage range of 1.65 V to 5.5 V. It features an internal programmable gain amplifier and a 2.04 V internal reference. The component is housed in a 32-pin WQFN package and communicates via a standard SPI interface.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-channel multiplexer with an internal programmable gain amplifier for flexible input configuration.
• Provides high-speed data conversion capabilities with a maximum sampling rate of 860 kSPS.
• Includes an internal 2.04 V reference and low-drift oscillator to minimize external component requirements.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition.
• Portable battery-powered instrumentation due to low power consumption modes.
• Medical equipment such as ECG and patient monitoring devices.
• Data acquisition systems for environmental sensing and structural health monitoring.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free manufacturing status according to Texas Instruments documentation. Confirm the 'CT' suffix corresponds to Cut Tape packaging rather than Reel or Tray formats. Ensure the operating temperature grade matches the design requirements for the intended application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high channel count and moderate resolution are required without external amplifiers. Compare against the ADS1158IRTCR if packaging preferences differ between cut tape and reel. Evaluate power consumption specifications against system battery life constraints. Consider the available EVM for initial hardware validation before final integration.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1158 family of 16-bit ADCs designed for precision applications. It serves as a direct replacement for the ADS1158IRTCR with potential differences in packaging or compliance markings. The device is widely used in scenarios demanding multiple differential or single-ended inputs within a compact footprint.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1158IRTCR is a primary equivalent part number within the same product family. Verify pin compatibility and electrical specifications before substitution. Check for any variations in packaging quantity or moisture sensitivity levels associated with different suffixes.
