LTC1865LACS8#PBF

Analog To Digital Converters (ADC) Overview

The Analog Devices LTC1865LACS8#PBF is a 16-bit, 150ksps successive approximation register (SAR) analog-to-digital converter (ADC) housed in an 8-lead MSOP package. Operating on a single 3V supply, it draws 450µA at maximum sampling rates and reduces to 10µA in auto-shutdown mode. The device features a software-selectable 2-channel multiplexer with true differential inputs and an external reference pin. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface for data transfer.

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 for differential or single-ended inputs
• Auto-shutdown capability reducing current to 10µA at 1ksps

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 'ACMS8' corresponds to the commercial temperature range (0°C to 70°C) and MSOP-8 packaging as defined in the manufacturer's order guide. Confirm RoHS compliance status through official documentation prior to procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption with a single 3V supply. Ensure the system supports the required 3-wire serial interface. For designs needing two input channels, verify that the software-configurable multiplexer meets the signal routing requirements compared to fixed single-channel alternatives.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1864L/LTC1865L family of µPower ADCs. The LTC1865L variant specifically provides a 2-channel multiplexer, whereas the LTC1864L offers a single differential channel. Both share similar power characteristics and package options within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1865LACS8#PBF is pin-compatible with the 12-bit LTC1861L. Designers upgrading from 12-bit architectures should verify that the increased resolution and voltage levels are supported by the existing system components.
