LTC1279CG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1279CG#PBF is a 12-bit, 600ksps sampling A/D converter in a 24-lead SSOP package. It operates from a single 5V or ±5V supply with typical power dissipation of 60mW at full speed and 8.5mW in shutdown mode. The device features an internal synchronized clock, a precision 2.42V reference, and a flexible parallel interface. Key electrical parameters include ±1LSB INL and DNL, 70dB S/(N+D) at 100kHz input, and a full linear bandwidth of 500kHz. It supports unipolar (0V to 5V) and bipolar (±2.5V) input ranges.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix CG#PBF corresponds to the commercial temperature range and lead-free packaging requirements. Confirm that the 24-lead SSOP footprint matches the target PCB design. Ensure the ordering documentation explicitly lists Analog Devices as the manufacturer to avoid counterfeit components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 600ksps throughput are required with low power consumption. Consider the internal clock feature if external clock generation is undesirable. Evaluate the 60mW power dissipation against thermal constraints in the final enclosure design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1279 family of high-speed successive approximation ADCs. It shares architectural similarities with the LTC1277 but offers higher sampling rates. The CG variant denotes the commercial temperature grade housed in a standard plastic SSOP package.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the LTC1277 for lower speed requirements. Verify pin compatibility and interface logic levels before swapping. Check datasheet updates for any changes in timing characteristics or power specifications.
