LTC1864CMS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1864CMS8#TRPBF is a 16-bit, 250ksps analog-to-digital converter (ADC) in an 8-lead MSOP package. It operates on a single 5V supply with a typical supply current of 850μA at maximum sampling rate. The device features true differential inputs and an adjustable reference pin. It utilizes a switched capacitor successive approximation architecture with integrated sample-and-hold. The part supports auto-shutdown, reducing current to 2μA at 1ksps. It communicates via a 3-wire serial interface compatible with SPI/MICROWIRE standards.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component matches the specific ordering suffix #TRPBF for tape and reel packaging and lead-free finish. Confirm the temperature range corresponds to the 'C' grade (0°C to 70°C). Ensure the source documentation aligns with the official Analog Devices datasheet 18645fb for accurate electrical specifications and pin configurations.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring high resolution and moderate speed in a compact footprint. The LTC1864 offers a 1-channel differential input, whereas the LTC1865 provides a 2-channel multiplexed input. Consider the power consumption profile, as current drops significantly at lower sampling rates due to auto-shutdown features. Ensure the external reference voltage meets the 1V to VCC requirement if using the adjustable reference pin.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1864/LTC1865 family of µPower ADCs. It serves as a 16-bit upgrade to the 12-bit LTC1286/LTC1298 series. The LTC1864CMS8#TRPBF is pin-compatible with the 12-bit LTC1860/LTC1861 devices, facilitating direct upgrades in existing designs without PCB layout changes.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers include LTC1864IMS8#TRPBF for extended temperature range (-40°C to 85°C) and LTC1864HMS8#TRPBF for industrial temperature range (-40°C to 125°C). For 2-channel functionality, consider the LTC1865CMS8#TRPBF.
