LTC1286IN8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1286IN8#PBF is a micropower, 12-bit successive approximation sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 4.5V to 9V and features a differential analog input with an external reference pin. The device typically draws 250µA of supply current when sampling at 12.5ksps 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. The component is housed in an 8-lead plastic DIP package.

Analog To Digital Converters (ADC) Feature Summary

• On-chip sample-and-hold with 12.5ksps maximum sampling rate

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 specific ordering suffix IN8 corresponds to the industrial temperature range (-40°C to 85°C) and the 8-lead PDIP package configuration as defined in the manufacturer's documentation. Confirm RoHS compliance status through official Analog Devices channels prior to procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1286IN8#PBF for applications requiring a single differential input channel and operation within a 4.5V to 9V supply range. Ensure the system clock frequency does not exceed 200kHz at 5V operation. Consider the LTC1298 variant if a two-channel multiplexer is required instead of a fixed differential input.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1286/LTC1298 family of micropower sampling ADCs. The 'I' designation indicates the industrial temperature grade, while 'N8' specifies the 8-lead plastic DIP package. The '#PBF' suffix denotes lead-free finish and RoHS compliance according to manufacturer standards.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1286CN8#PBF serves as a commercial temperature grade alternative (0°C to 70°C). For dual-channel multiplexing requirements, the LTC1298 series is the functional equivalent within the same package.
