LTC1098ACS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1098ACS8#TRPBF is an 8-bit successive approximation register (SAR) 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 3V to 6V. 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 total unadjusted error of ±0.5LSB over the temperature range. Data transfer occurs via a synchronous serial interface compatible with standard microprocessor ports.

Analog To Digital Converters (ADC) Feature Summary

• Micropower consumption: 80μA active, 1nA shutdown
• 8-bit resolution with 33kHz sample rate
• Software-selectable 2-channel input multiplexer
• ±0.5LSB total unadjusted error over temperature

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 that the component matches the specified 8-pin SOIC package and the 3V to 6V operating voltage range. Confirm the suffix #TRPBF indicates tape and reel packaging for automated assembly. Ensure the 'A' grade designation aligns with the required ±0.5LSB accuracy specifications for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a two-channel input capability is required, distinguishing it from the single-channel LTC1096. Verify that the system power supply remains within the 3V to 6V limit, as higher voltages may exceed absolute maximum ratings. Consider the 10μs wake-up time requirement if the device is frequently cycled between active and shutdown states at high clock frequencies.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1096/LTC1098 family of micropower sampling ADCs. The LTC1098 variant specifically includes a 2-channel multiplexer, whereas the LTC1096 offers a differential input. Both share the same SAR architecture and low-power characteristics but differ in input configuration and reference pin usage.
