Analog To Digital Converters (ADC) Procurement Notes

Verify the 'I' suffix indicates an industrial temperature range of -40°C to +85°C. Confirm the 'SW' suffix corresponds to the 28-lead plastic SOIC package. Ensure '#PBF' denotes lead-free compliance. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current production status and availability.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high linearity and fast conversion speeds within a single channel. The ±2.5V input range suits bipolar signals without additional scaling circuitry. Consider the parallel interface requirements and ensure the driving source impedance is low enough to meet the 90ns acquisition time specification at full throughput.

Analog To Digital Converters (ADC) Part Context

The LTC1419 series comprises 14-bit, 800ksps ADCs with shutdown capabilities. Variants include the 'C' (commercial, 0°C to 70°C) and 'I' (industrial, -40°C to 85°C) temperature grades. Packages available are SSOP (G) and SOIC (SW). The ISW variant specifically denotes the industrial grade in the 28-lead SOIC package.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes are not identified in the provided datasheet. The LTC1416 is a related 400ksps variant. Verify pin compatibility and electrical specifications against any potential cross-model replacements before implementation.
