ADS1158IRTCT

Analog To Digital Converters (ADC) Overview

The ADS1158IRTCT is a 16-channel, 16-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features an integrated multiplexer and programmable gain amplifier (PGA), supporting both differential and single-ended input configurations. The device utilizes a delta-sigma architecture with a maximum data rate of 860 samples per second per channel. It operates on a single supply voltage ranging from 2.7V to 5.5V and includes an internal reference and oscillator. Communication is handled via a standard SPI-compatible interface. The component is housed in a VQFN package and is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRTC against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required operating temperature range and pinout configuration for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by your manufacturing standards.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high channel count is required without external multiplexing circuitry. The integrated PGA reduces the need for discrete amplifiers in low-voltage signal paths. Consider the 860 SPS maximum update rate to ensure it meets the bandwidth requirements of your application. Evaluate power consumption constraints as the device supports low-power modes suitable for battery-operated systems.

Analog To Digital Converters (ADC) Part Context

The ADS1158 belongs to Texas Instruments' family of high-resolution, multi-channel ADCs designed for precision measurement applications. It consolidates multiple functions typically found in separate components into a single small footprint. This integration simplifies board design and reduces overall system cost compared to discrete solutions using separate muxes and ADCs.

Analog To Digital Converters (ADC) Replacement Considerations

Check for ADS1158IRTC or ADS1158EVM variants which may share identical electrical characteristics but differ in packaging or evaluation support. Verify pin compatibility before substituting any alternative models. Consult the latest TI datasheet for any functional updates or recommended upgrades within the same product line.
