ADS7253IRTET

Analog To Digital Converters (ADC) Overview

The ADS7253IRTET 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 and features simultaneous sampling capabilities for both channels. The device supports differential, pseudo-differential, and single-ended input configurations via an SPI-compatible serial interface. 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. The component achieves a signal-to-noise ratio of 73.5 dB and is housed in a 16-pin WQFN package rated for operation up to 125°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling architecture ensures precise phase alignment between two independent channels without interleaving delays.
• Flexible input configuration supports differential, pseudo-differential, and single-ended signal connections for diverse sensor interfaces.
• Integrated sample-and-hold circuitry maintains signal integrity during the conversion cycle for accurate data acquisition.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel temperature or pressure monitoring
• Data acquisition modules for factory automation and machinery health monitoring
• Portable instrumentation devices utilizing battery-powered single-supply operation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRTET' corresponds to the tape-and-reel packaging format when ordering. Confirm that the industrial temperature range rating aligns with the operational environment requirements. Ensure compatibility with the target system's logic voltage levels, as the digital interface supports a wide range from 1.65 V to 5.5 V. Cross-reference the manufacturer datasheet for any recent pinout or electrical specification updates before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is critical for phase-sensitive applications. Choose this part over sequential sampling ADCs if channel-to-channel timing skew must be minimized. Consider the 12-bit resolution and 1 MSPS speed as sufficient for most general-purpose industrial sensing tasks. Verify that the WQFN-16 package footprint fits within the available PCB area constraints.

Analog To Digital Converters (ADC) Part Context

The ADS7253IRTET belongs to the ADS7253 family of dual-channel SAR ADCs from Texas Instruments. This series is designed for high-speed, low-power data acquisition applications. The device shares architectural similarities with other members like the ADS7250 and ADS7254, differing primarily in sampling rates and input types. It serves as a key component in mixed-signal systems requiring reliable analog-to-digital conversion.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7250IRTET offers similar functionality but operates at a lower sampling rate of 750 kSPS. The ADS7254IRTET provides comparable performance but supports only differential inputs. Verify pin compatibility and software register settings when substituting these variants to ensure seamless integration into existing designs.
