LTC1865LCMS#PBF

Analog To Digital Converters (ADC) Overview

The LTC1865LCMS#PBF is a 16-bit, 2-channel successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It operates on a single 3V supply with a maximum sampling rate of 150ksps and typical supply current of 450µA. The device features an auto-shutdown mode that reduces current to 10µA at 1ksps. It includes a software-selectable multiplexer for two input channels and an external reference pin. The component utilizes a 3-wire serial interface compatible with SPI/MICROWIRE standards and is housed in a 10-lead MSOP package.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with 150ksps sampling rate
• Single 3V supply operation with 450µA typical current consumption
• Software-selectable 2-channel multiplexer
• Auto-shutdown mode reducing current to 10µA

Analog To Digital Converters (ADC) Applications

• High speed data acquisition systems
• Portable or compact instrumentation
• Low power battery-operated instrumentation
• Isolated and/or remote data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the operating temperature range corresponds to the 'C' suffix, which indicates commercial grade operation from 0°C to 70°C. Confirm the package type is MSOP-10 and ensure compatibility with the system's 3V logic levels. Check for RoHS compliance status as per manufacturer specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this part when a low-power, 16-bit ADC is required for dual-channel applications. It serves as a direct upgrade to 12-bit LTC1285/LTC1288 devices and is pin-compatible with LTC1860L/LTC1861L. Ensure the application supports external voltage references, as internal references are not provided.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1864L/LTC1865L family of µPower ADCs. The LTC1865L variant specifically provides two input channels via a multiplexer, whereas the LTC1864L offers a single differential input. Both share similar electrical characteristics and packaging options.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible replacements include the LTC1860L and LTC1861L (12-bit versions). For higher performance requirements, consider the non-L variants such as LTC1865, which offer 250ksps sampling rates but require a 5V supply.
