LTC1098LCS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1098LCS8#TRPBF is an 8-bit micropower successive approximation analog-to-digital converter (ADC) from Analog Devices Inc. It features a software-selectable two-channel multiplexer and operates on a single supply voltage ranging from 2.65V to 4V. The device draws a maximum of 80μA during conversion and automatically powers down to 1nA typical current when inactive. It supports sampling rates up to 33kHz with a 16μs conversion time. Data transfer occurs via a synchronous serial interface, and the component is housed in an 8-lead plastic SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the specific ordering suffix corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards as indicated by the manufacturer's documentation. Ensure the supply voltage requirements align with the 2.65V to 4V operational range specified for the L-series variant.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring low power consumption and dual-channel input capability within a compact 8-pin SOIC footprint. The L-series designation indicates compatibility with lower supply voltages starting at 2.65V. Ensure the system clock frequency does not exceed 250kHz when operating at the minimum supply voltage to maintain performance specifications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1098 family of micropower ADCs. The 'L' suffix denotes the low-voltage version capable of operating down to 2.65V. The 'C' indicates the commercial temperature range of 0°C to 70°C. The 'S8' specifies the 8-lead SOIC package, and '#TRPBF' identifies the lead-free tape and reel packaging configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1098CS8#TRPBF serves as a functional substitute but operates on a higher voltage range of 3V to 6V. Verify that the system supply voltage remains within the acceptable limits of the replacement part before implementation.
