LTC1298IS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1298IS8#PBF is a micropower, 12-bit successive approximation analog-to-digital converter (ADC) housed in an 8-lead plastic SOIC package. It features a software-selectable two-channel multiplexer and operates on a single 4.5V to 5.5V supply. The device draws typical supply current of 360µA at maximum sampling rates and powers down to 1nA when inactive. It includes an on-chip sample-and-hold circuit and communicates via a synchronous serial interface compatible with SPI and Microwire standards.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with guaranteed ±3/4 LSB max DNL
• Two-channel input multiplexer for differential or single-ended measurements
• Automatic shutdown mode reduces supply current to 1nA typical
• Serial interface supports data transfer over three wires

Analog To Digital Converters (ADC) Applications

• Battery-operated systems
• Remote data acquisition
• Battery monitoring
• Temperature measurement

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IS8 indicates the industrial temperature range (-40°C to 85°C) and SOIC-8 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply voltage constraints between 4.5V and 5.5V are strictly maintained during operation.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption and multi-channel input capabilities within a small footprint. The LTC1298 is suitable where external reference pins are not required, as the reference is tied to the supply pin. Compare against the LTC1286 if a dedicated external reference input and wider supply voltage range up to 9V are necessary instead.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1286/LTC1298 family of micropower sampling ADCs. While sharing the same core 12-bit SAR architecture and S0-8 packaging, the LTC1298 differs from the LTC1286 by integrating a two-channel multiplexer and fixing the reference input to the VCC pin, whereas the LTC1286 offers a single differential input and separate VREF pin.
