LTC1286CS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1286CS8#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. It includes an on-chip sample-and-hold circuit and automatically powers down to a typical leakage current of 1nA when not performing conversions. Data transfer is managed via a serial interface compatible with SPI and Microwire protocols.

Analog To Digital Converters (ADC) Feature Summary

• Battery monitoring
• Temperature measurement
• Isolated data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CS8' corresponds to the commercial temperature range (0°C to 70°C) and SOIC-8 package configuration as defined in the manufacturer's ordering guide. Confirm that the '#PBF' designation indicates lead-free and RoHS compliance status according to current Analog Devices material declarations before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1286CS8#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 for optimal performance at 5V supplies. Consider the LTC1288 if a lower 3V supply voltage or single-ended input architecture is required instead of the differential configuration provided by this model.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1286/LTC1298 family of micropower sampling ADCs. While the LTC1298 variant offers a two-channel multiplexer and a fixed 4.5V to 5.5V supply range, the LTC1286 provides a dedicated differential input structure and supports higher supply voltages up to 9V. Both devices share the same 12-bit SAR architecture and low-power characteristics.
