LTC1098LIS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1098LIS8#PBF is an 8-bit micropower sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a software-selectable 2-channel multiplexer and operates on a single supply voltage ranging from 2.65V to 4V. The device draws 80μA maximum supply current during conversion and typically 1nA in shutdown mode. It utilizes a switched-capacitor successive approximation architecture with an integrated sample-and-hold circuit. Data transfer occurs via a synchronous serial interface, requiring three wires for the LTC1096 variant or four for the LTC1098. The component is housed in an 8-lead plastic SOIC package and supports a maximum sampling frequency of 33kHz.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Applications

• Battery-operated systems
• Remote data acquisition
• Battery monitoring and gas gauges
• Temperature measurement
• Isolated data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the part number suffix #PBF indicates lead-free finish and tape and reel packaging availability if required. Confirm the 'I' grade designation corresponds to the –40°C to 85°C industrial temperature range. Ensure the S8 package type matches the PCB footprint requirements. Cross-reference the manufacturer's official documentation for specific ordering suffixes and environmental compliance details.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1098LIS8#PBF when a 2-channel multiplexed input is required for 8-bit precision applications. This model is suitable for designs operating between 2.65V and 4V. Compare against the LTC1096 series if a differential single-ended input without multiplexing is preferred. Consider the 33kHz maximum sampling rate and 16μs conversion time for system timing constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1096/LTC1098 family of micropower 8-bit ADCs. The LTC1098 variant specifically includes a 2-channel multiplexer, distinguishing it from the single-input LTC1096. The 'L' suffix denotes low-voltage operation (2.65V minimum), while 'IS8' specifies the industrial temperature range and 8-lead SOIC package. The '#PBF' suffix confirms lead-free manufacturing.
