ADS7254IRTET

Analog To Digital Converters (ADC) Overview

The ADS7254IRTET is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 1 MSPS per channel and supports simultaneous sampling for both inputs. The device utilizes a WQFN-16 package and accepts differential input signals. It requires an analog supply voltage ranging from 4.5 V to 5.5 V and a digital supply voltage between 1.65 V and 5.5 V. Key performance metrics include a signal-to-noise ratio (SNR) of 74 dB and a SINAD of 73.9 dB. The component features an SPI serial interface and offers both internal and external reference options.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to ensure the correct tape-and-reel packaging format matches your assembly requirements. Confirm that the industrial temperature range specifications align with your operational environment constraints. Cross-reference the datasheet revision history to ensure compatibility with existing design documentation and pinout configurations before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is required at speeds up to 1 MSPS. Ensure the system design accommodates the specified analog and digital supply voltage ranges. Consider the WQFN-16 package dimensions for PCB layout constraints. Verify that the SPI interface timing parameters meet the microcontroller or DSP clock requirements of the host system.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7254 family of dual-channel SAR ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7250 and ADS7253 but differs in sampling speed and input type specifications. The IRTET suffix indicates the industrial temperature grade and WQFN-16 reel packaging. It serves as a high-performance alternative to single-channel solutions in compact form factors.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7254IPWR is a parameter-equivalent alternative in a TSSOP-16 package. ADS7253IRTET offers similar performance but supports pseudo-differential and single-ended inputs in addition to differential. ADS7251IRTET provides higher sampling rates but may differ in power characteristics.
