LTC1098LIS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1098LIS8#TRPBF is an 8-bit micropower successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices Inc. It features a software-selectable 2-channel multiplexer and operates on a single supply voltage ranging from 2.65V to 4.0V. The device draws a maximum of 80μA during conversion and automatically powers down to a typical 1nA in shutdown mode. It utilizes a synchronous serial interface for data transfer and includes an internal sample-and-hold circuit. The component is housed in an 8-lead plastic SOIC package and is rated for an industrial operating temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Feature Summary

• Micropower consumption with 80μA active current and 1nA shutdown current
• 2-channel input multiplexer with software selection
• 3V/3.3V compatible operation (2.65V to 4.0V supply range)
• Integrated sample-and-hold with 33kHz maximum sampling rate

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 specific ordering suffix #TRPBF confirms tape and reel packaging. Confirm the 'I' grade designation matches the required –40°C to 85°C industrial temperature range. Ensure the 'L' variant is selected for 3V logic compatibility rather than the standard 5V version.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the non-L variant if the system operates below 5V, as the standard LTC1098 supports up to 6V but requires higher voltage levels. Choose the IS8 package for surface mount applications requiring industrial temperature stability. Verify that the 8-bit resolution and 33kHz speed meet the application's bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1096/LTC1098 family of micropower ADCs. The 'L' suffix indicates low-voltage operation suitable for 3V systems. The 'I' suffix denotes the industrial temperature grade. The 'S8' specifies the 8-lead SOIC package, and '#TRPBF' indicates lead-free tape and reel packaging.
