ADS8558IPMR

Analog To Digital Converters (ADC) Overview

The ADS8558IPMR is a six-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 730 kSPS per channel and supports simultaneous sampling across all channels. The device accepts single-ended inputs and features both parallel and serial digital interfaces. It requires an analog supply voltage between 4.5 V and 5.5 V and a digital supply voltage ranging from 2.7 V to 5.5 V. The component is housed in a 64-pin LQFP package and includes an internal oscillator. It offers a signal-to-noise ratio of 73.9 dB, with differential nonlinearity of +/- 0.5 LSB and integral nonlinearity of +/- 0.75 LSB.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPMR against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration. Ensure that the ordering information matches the exact pinout and electrical specifications defined in the current datasheet revision. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement actions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a design requires six channels of simultaneous sampling at 12-bit resolution. It is suitable for applications where single-ended input signals are present and a SAR architecture provides the necessary speed. Consider the available board space for the 64-pin LQFP package and ensure the system can accommodate the required dual voltage supplies for optimal performance.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS8558 family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with other members of the series but is distinguished by its 12-bit resolution and six-channel configuration. The IPMR suffix indicates a specific packaging variant designed for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the manufacturer's product selection guide for direct replacements within the ADS8558 family. Verify compatibility regarding pin assignments, voltage levels, and interface protocols before substituting with alternative part numbers.
