LTC1865LCS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1865LCS8#TRPBF is a 16-bit, 150ksps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It operates on a single 3V supply with a typical supply current of 450µA at maximum sampling rate. The device features a software-selectable 2-channel multiplexer and an external reference pin in the MSOP-8 package. It utilizes a 3-wire serial interface compatible with SPI/MICROWIRE standards. Key performance metrics include a signal-to-noise ratio of 82 dB, full power bandwidth of 10 MHz, and integral nonlinearity of ±6 LSB. The component supports auto-shutdown, reducing current to 10µA at 1ksps.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with 150ksps sampling rate
• Single 3V supply operation with 450µA typical current
• Software-selectable 2-channel MUX in MSOP-8 package
• Auto-shutdown mode reduces 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 specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the LCS8 designation corresponds to the commercial temperature range (0°C to 70°C) and MSOP-8 package variant. Ensure compatibility with single 3V supply requirements for the target application design.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring low power consumption with 16-bit precision at moderate speeds. The LTC1865L differs from the standard LTC1865 by operating on a 3V supply rather than 5V, with a reduced sampling rate of 150ksps compared to 250ksps. Verify that the external reference voltage requirement aligns with the system's available reference sources, as the MSOP version does not have an internal fixed reference.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1864L/LTC1865L family of µPower ADCs. It serves as a 16-bit upgrade path for older 12-bit devices like the LTC1860L/LTC1861L, maintaining pin compatibility. The LTC1865L specifically provides dual-channel input capability via a multiplexer, distinguishing it from the single-channel LTC1864L.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed pin-compatible replacements include the LTC1864L/LTC1865L (5V, 250ksps) and the 12-bit LTC1860L/LTC1861L series. Verify voltage supply constraints and sampling rate requirements when substituting these variants.
