ADS7253IPW

Analog To Digital Converters (ADC) Overview

The ADS7253IPW is a dual-channel, simultaneous-sampling Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) manufactured by Texas Instruments. It features a 12-bit resolution and supports a maximum sampling rate of 1 MSPS per channel. The device operates with an analog supply voltage range of 4.5 V to 5.5 V and a digital supply voltage range of 1.65 V to 5.5 V. It utilizes a serial Peripheral Interface (SPI) for data communication. The component is housed in a 16-pin TSSOP package and is rated for an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling architecture ensures precise phase alignment between the two input channels.
• Integrated sample-and-hold circuitry on each channel allows independent signal acquisition.
• Flexible input configuration supports differential, pseudo-differential, and single-ended signal types.

Analog To Digital Converters (ADC) Applications

• Multi-axis motor control systems requiring synchronized current sensing
• Industrial process monitoring with multiple isolated sensor inputs
• Data acquisition modules for vibration analysis

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPW corresponds to the TSSOP-16 package variant when sourcing. Confirm that the required operating temperature range aligns with the industrial grade specifications. Ensure the design accommodates the separate analog and digital power supply requirements. Check for availability of compatible EMI filtering components for the high-speed digital interface.

Analog To Digital Converters (ADC) Selection Notes

Select this model when simultaneous sampling of two signals is critical for maintaining phase integrity. Compare against the ADS7254 if higher pin count or different packaging is preferred. Consider the ADS7251 if a higher sampling rate of 2 MSPS is required, noting the architectural differences. Verify that the SPI clock speed meets the system timing constraints for the 1 MSPS throughput.

Analog To Digital Converters (ADC) Part Context

The ADS7253 belongs to the ADS725x family of low-power, simultaneous-sampling ADCs. This series is designed for applications requiring accurate correlation between multiple analog inputs. The IPW suffix denotes the plastic small-outline package with leads, distinguishing it from QFN variants like the IRTET which offer different thermal and footprint characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7254IPWR is a functionally similar dual-channel SAR ADC in a TSSOP package. Verify pinout compatibility and software register settings before substitution. The ADS7253IRTET offers the same electrical performance but in a WQFN package, requiring PCB layout adjustments.
