LTC1864AIS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1864AIS8#PBF is a 16-bit, 250ksps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It operates on a single 5V supply with a typical supply current of 850μA at maximum sampling rates, dropping to 2μA in shutdown mode. The device features true differential analog inputs and an adjustable reference pin. It utilizes a 3-wire serial interface compatible with SPI/MICROWIRE standards. Packaged in an 8-lead plastic MSOP, it supports industrial temperature ranges from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with 250ksps sampling rate
• Single 5V supply operation with auto-shutdown capability
• True differential analog inputs for common-mode noise rejection
• SPI/MICROWIRE compatible 3-wire 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 remote data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the design requirements, as this specific part number denotes the MSOP variant. Confirm that the operating temperature range of -40°C to +85°C aligns with the system environment. Ensure the external reference voltage connected to VREF falls within the specified 1V to VCC range for proper ADC functionality.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1864AIS8#PBF when a single-channel, high-resolution ADC with low power consumption is required. This model is suitable for applications needing direct connection to signal sources without external gain stages due to its high impedance inputs. Consider the LTC1865 if a second channel or multiplexing capability is necessary instead.

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 series and is pin-compatible with the 12-bit LTC1860/LTC1861 devices. The 'AI' suffix indicates the industrial temperature grade (-40°C to +85°C), while 'S8' specifies the 8-lead MSOP package.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1864LIS8#PBF is listed as a parameter-equivalent substitute. Verify that the performance specifications of any replacement part meet the original design requirements before implementation.
