LTC1286IS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1286IS8#PBF is a micropower, 12-bit successive approximation sampling analog-to-digital converter (ADC) housed in an 8-lead plastic SOIC package. It features a single differential analog input and operates on a single supply voltage ranging from 4.5V to 9V. The device typically draws 250µA of supply current when converting at a maximum sampling rate of 12.5 ksps and automatically powers down to a typical leakage current of 1nA during idle periods. It includes an on-chip sample-and-hold circuit and communicates via a serial interface compatible with SPI and Microwire protocols.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with guaranteed max DNL of -3/4 LSB

• Serial interface compatible with standard microprocessor buses

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the component matches the specific Analog Devices part number LTC1286IS8#PBF. Confirm the suffix indicates lead-free composition and RoHS compliance as per manufacturer standards. Ensure the package type is identified as SOIC-8 for physical compatibility. Cross-reference the operating temperature range (-40°C to +85°C) with system requirements before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption and moderate speed. The LTC1286 is suitable for single-channel differential measurements. If multiplexing between two channels is required, consider the LTC1298 variant instead. Ensure the external reference voltage does not exceed the supply voltage limits defined in the datasheet to maintain accuracy.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1286/LTC1298 family of micropower 12-bit ADCs. The 'I' suffix denotes an industrial temperature range of -40°C to +85°C, while the 'S8' suffix specifies the 8-lead SOIC plastic package. The '#PBF' suffix indicates that the device is manufactured in a lead-free and RoHS-compliant configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1286CN8 or LTC1286IN8 are alternative package options within the same series. For dual-channel multiplexing requirements, the LTC1298IS8#PBF serves as a functional equivalent with added MUX capabilities. Verify pinout compatibility when substituting with other 12-bit SAR ADCs.
