ADS1158IRTCR

Analog To Digital Converters (ADC) Overview

The ADS1158IRTCR is a 16-channel, 16-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features an integrated multiplexer allowing connection to various single-ended or differential inputs. The device operates with a supply voltage range of 2.375 V to 5.25 V and supports data rates up to 860 samples per second. It utilizes a serial peripheral interface (SPI) for communication and includes an internal programmable gain amplifier. The component is housed in a 48-pin TQFP package and is rated for operation from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRTCR against the manufacturer's official datasheet to confirm pinout, temperature grade, and packaging details. Ensure compatibility with system voltage levels and SPI timing requirements before integration. Cross-reference the part number with authorized distributors to validate authenticity and current production status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high channel count and resolution are required in a compact form factor. Consider the internal multiplexer and PGA to reduce external passive components. Evaluate the maximum sampling rate against the Nyquist requirement of the input signals. Verify that the operating temperature range meets the environmental constraints of the target application.

Analog To Digital Converters (ADC) Part Context

The ADS1158 belongs to the ADS115x family of precision analog-to-digital converters. This series is designed for applications demanding multiple channels with high accuracy. The IRTCR variant specifies the industrial temperature range and tape-and-reel packaging format, distinguishing it from other commercial or evaluation versions within the same functional family.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible alternatives within the ADS115x family. Verify if lower-cost or higher-speed variants meet the system specifications. Ensure any substitute maintains the 16-bit resolution and 16-channel multiplexing capability.
