ADS7253IPWR

Analog To Digital Converters (ADC) Overview

The ADS7253IPWR is a dual-channel, simultaneous-sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 12-bit resolution and operates at a sampling rate of 1 MSPS per channel. The device utilizes a SAR architecture and accepts differential or pseudo-differential inputs. It functions with an analog supply voltage range of 4.5 V to 5.5 V and a digital I/O supply range of 1.65 V to 5.5 V. Communication is handled via a high-speed SPI interface. The component is housed in a 16-pin TSSOP package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling capability for two independent channels ensures precise phase alignment between input signals.
• Integrated sample-and-hold circuitry on each channel allows for independent signal acquisition without cross-talk interference.
• Flexible power supply design separates analog and digital domains, supporting low-voltage digital logic interfacing.

Analog To Digital Converters (ADC) Applications

• Multi-channel data acquisition systems requiring synchronized signal capture
• Industrial process control applications involving vibration or acoustic monitoring
• Medical instrumentation requiring high-fidelity multi-lead signal digitization

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPWR against official Texas Instruments documentation to confirm the tape-and-reel packaging format and commercial grade temperature rating. Ensure the ordering part number matches the required pin configuration and RoHS compliance status before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is critical for maintaining signal integrity. Compare performance metrics such as SNR and THD against single-channel alternatives if space constraints allow. Verify that the SPI clock speed requirements of the host processor are compatible with the ADC's maximum conversion time specifications.

Analog To Digital Converters (ADC) Part Context

The ADS7253 belongs to the ADS725x family of low-power, simultaneous-sampling ADCs. This series includes variants with different resolutions and channel counts. The IPWR suffix specifically denotes the surface-mount TSSOP package variant designed for automated assembly processes in compact electronic designs.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the Texas Instruments ADS7253 datasheet for officially listed pin-compatible or functionally equivalent replacements. Verify that any substitute maintains the 12-bit resolution and simultaneous sampling architecture to ensure system compatibility.
