LTC1864ACS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1864ACS8#PBF 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 typical supply current of 850μA at maximum sampling rate, dropping to 2μA in shutdown mode. The device features true differential analog inputs and an adjustable external reference pin. It utilizes a 3-wire serial interface compatible with SPI/MICROWIRE standards. Packaged in an 8-lead plastic SOIC, it supports ratiometric applications or external references, offering high speed-to-power efficiency for compact systems.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the 'A' grade designation corresponds to the commercial temperature range of 0°C to +70°C. Ensure compatibility with the 8-lead SOIC footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring 16-bit precision at moderate speeds with low power consumption. The LTC1864 provides a single-channel differential input; consider the LTC1865 if two-channel multiplexing is required. Verify that the external reference voltage meets the 1V to VCC operating range requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1864/LTC1865 family of µPower ADCs. It serves as a 16-bit upgrade to the 12-bit LTC1286/LTC1298 series and is pin-compatible with the 12-bit LTC1860/LTC1861 devices, facilitating design transitions while improving resolution.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet lists the LTC1864IS8#PBF as a pin-compatible alternative with an extended industrial temperature range (-40°C to 85°C). Other family members like the LTC1865 offer dual-channel functionality.
