LTC1865LIS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1865LIS8#TRPBF is a 16-bit, 150ksps Analog-to-Digital Converter (ADC) from Analog Devices Inc., housed in an 8-lead MSOP package. Operating on a single 3V supply, it draws 450µA at maximum sampling rate and reduces to 10µA in auto-shutdown mode. The device features a software-selectable 2-channel multiplexer, true differential inputs, and an external reference pin. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface. Key electrical parameters include a typical SNR of 82dB, full power bandwidth of 10MHz, and guaranteed operation over the industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 16-Bit Resolution with 150ksps Sampling Rate
• Single 3V Supply Operation with Low Power Consumption (450µA typ)
• Software-Selectable 2-Channel Multiplexer
• 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 that the ordering suffix #TRPBF corresponds to the tape and reel packaging format as specified by Analog Devices. Confirm the 'I' grade designation indicates the extended industrial temperature range (-40°C to +85°C). Ensure the component is sourced from authorized distributors to guarantee authenticity and proper handling for the MSOP package.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 2-channel input capability is required within a compact MSOP footprint. It serves as a direct 16-bit upgrade to 12-bit LTC1860L/LTC1861L devices while maintaining pin compatibility. Choose this variant over the LTC1865L (5V version) if the system operates strictly on a 3V rail, as it offers lower power dissipation (1.22mW) compared to the 5V counterpart.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1864L/LTC1865L family of µPower ADCs. The LTC1865L specifically denotes the 2-channel multiplexed version, whereas the LTC1864L is a single-channel device. Both share identical core architecture, power profiles, and interface protocols, differing primarily in analog input configuration and pin assignments for the second channel.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible replacements include the 12-bit LTC1860L and LTC1861L for cost-down applications requiring fewer bits. For higher speed requirements, the 5V-supply LTC1865 may be considered if voltage levels are compatible, though power consumption will increase significantly.
