LTC1418IG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1418IG#PBF is a low-power, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates at a sampling rate of 200ksps and supports both serial and parallel data output formats. The device functions from a single 5V supply or ±5V supplies, accommodating input ranges of 0V to 4.096V or ±2.048V respectively. Key electrical specifications include ±1.25LSB maximum integral nonlinearity (INL), ±1LSB differential nonlinearity (DNL), and typical power dissipation of 15mW. It features an internal 2.5V reference, high-impedance differential analog inputs, and two user-selectable power shutdown modes.

• Audio and telecom processing

Analog To Digital Converters (ADC) Procurement Notes

Verify the component marking '1418IG' on the package to confirm the industrial temperature grade (-40°C to 85°C). Ensure the ordering suffix '#PBF' corresponds to lead-free RoHS compliance. Confirm the package type is the 28-lead plastic SSOP. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 14-bit accuracy at 200ksps with low power constraints. Choose the IG suffix over the CG suffix if operation below 0°C is required. Verify that the system interface supports either SPI/MICROWIRE serial communication or parallel data transfer. Ensure the analog source impedance is managed to meet the 1µs acquisition time requirement for full throughput.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1418 family of low-power SAR ADCs. The 'I' designation indicates the industrial temperature range variant, distinct from the commercial 'C' grade. The '#PBF' suffix denotes a lead-free finish compliant with RoHS standards. It is housed in a 28-lead SSOP package designed for surface-mount assembly.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1418CG#PBF serves as a direct functional substitute within the same package but is rated for the commercial temperature range (0°C to 70°C) instead of the industrial range.
