LTC1864AHMS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1864AHMS8#TRPBF is a 16-bit, 250ksps successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices. It operates on a single 5V supply with a typical supply current of 850μA at maximum sampling rate. The device features true differential analog inputs and an adjustable reference pin. It utilizes auto-shutdown to reduce power consumption to 2μA at 1ksps. The component is housed in an 8-lead plastic MSOP package and supports extended industrial temperature operation from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Single 5V Supply Operation with 850μA Typical Current
• Auto Shutdown Mode Reduces Current to 2μA at 1ksps
• True Differential Inputs with Adjustable Reference Pin
• SPI/MICROWIRE Compatible Serial I/O Interface

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 specific ordering suffix #TRPBF confirms tape and reel packaging for the AH grade variant. Confirm the manufacturer is Analog Devices Inc. Ensure the part marking corresponds to LTHQ for the lead-free finish. Check RoHS compliance status as detailed in official documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 16-bit precision at high speeds within a compact MSOP footprint. The AH grade ensures guaranteed operation up to +125°C. Compare against the LTC1864AIMS8#TRPBF if a lower temperature range (-40°C to 85°C) is sufficient. Consider the LTC1865 series if two-channel multiplexing is required instead of a single differential input.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1864/LTC1865 family of µPower, 16-Bit ADCs. It serves as a 16-bit upgrade to the 12-bit LTC1286/LTC1298 and is pin-compatible with the 12-bit LTC1860/LTC1861. The AH suffix denotes the extended temperature range variant (-40°C to +125°C) packaged in an 8-lead MSOP.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers: LTC1864AIMS8#TRPBF (lower temp grade), LTC1864HMS8#TRPBF (non-A grade). Verify pin compatibility and electrical specifications before substitution.
