ADS7253IRTER

Analog To Digital Converters (ADC) Overview

The ADS7253IRTER 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. The device accepts differential, pseudo-differential, or single-ended analog inputs. 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. Communication is handled via a high-speed SPI interface. The component is housed in a 16-pin WQFN package with dimensions of 3x3 mm. It features an internal reference and exhibits a Signal-to-Noise Ratio (SNR) of 73.5 dB.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling capability for two independent channels ensures precise time alignment of input signals without inter-channel skew.
• Flexible input configuration supports differential, pseudo-differential, and single-ended signal types to accommodate various sensor interfaces.
• Integrated internal voltage reference reduces external component count and simplifies board layout requirements.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Medical instrumentation such as portable diagnostic devices
• Vibration monitoring and acoustic analysis equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix IRTER indicates tape-and-reel packaging when ordering. Confirm the I grade temperature range specifications match the operational environment requirements. Ensure the 16-WQFN footprint matches the design layout. Check RoHS compliance status against current regulatory standards for the target market.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the ADS7250IRTET if a higher sampling rate of 1 MSPS is required instead of 750 kSPS. Choose the ADS7254IRTET variant if strictly differential inputs are needed rather than pseudo-differential support. Consider the ADS7853 series if 14-bit resolution is necessary for higher precision applications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS7253 family of dual-channel SAR ADCs. It shares architectural similarities with the ADS7250 and ADS7254 models but offers specific input flexibility. The device is part of Texas Instruments' broader portfolio of precision data converters designed for embedded sensing applications.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7253IRTET serves as the tray-packaged equivalent. ADS7250IRTET provides similar functionality at a lower 750 kSPS speed. ADS7254IRTET offers identical performance with strict differential input support only.
