LTC1098IS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1098IS8#PBF is a microPOWER sampling 8-bit serial I/O analog-to-digital converter (ADC) manufactured by Analog Devices. It features a successive approximation register (SAR) architecture with a sampling rate of 33 kS/s. The device supports pseudo-differential or single-ended inputs and operates on a single 5 V supply. Key electrical specifications include a differential nonlinearity (DNL) of 1 LSB, an integral nonlinearity (INL) of 0.5 LSB, and a power dissipation of 780 µW. It is housed in an 8-pin SOIC package and operates within a temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the IS8 variant meets the commercial temperature range requirements of 0°C to +70°C. Ensure the external reference voltage matches the ADC input range for optimal accuracy. Check for availability constraints as distribution status may vary by region.

Analog To Digital Converters (ADC) Selection Notes

Select this component when low power consumption is critical alongside moderate speed requirements. The external reference pin allows flexibility in system design but requires careful selection of the reference source. Compare DNL and INL specifications against application tolerance levels. Consider the SOIC-8 package dimensions for PCB layout compatibility.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1098 family of microPOWER SAR ADCs. It shares architectural similarities with the LTC1096 but offers higher resolution. The IS8 designation specifies the industrial/commercial temperature grade and SOIC-8 package format. It serves as a cost-effective solution for applications requiring minimal power without sacrificing significant performance.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1098CS8#PBF is a verified equivalent part number within the same family, differing primarily in temperature grade or packaging lot variations. Verify pinout compatibility and electrical parameter equivalence before substitution.
