Analog To Digital Converters (ADC) Procurement Notes

Verify the 'I' suffix indicates the industrial temperature range (-40°C to +85°C). Confirm the '#PBF' suffix denotes lead-free finish and RoHS compliance. Ensure the package matches the 40-lead 6mm x 6mm QFN specification. Check for availability of development kits like DC1369A-N for evaluation purposes.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring low power consumption under 150mW at high speeds. Choose between CMOS or LVDS outputs based on system noise and trace length requirements. Use the serial SPI port to configure modes such as shutdown, nap, or data randomization. Ensure the analog input drive circuitry supports the required common mode voltage set by the VCM pin.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2262 family of ultralow power high-speed ADCs. It is pin-compatible with the 14-bit version (LTC2262-14) and other variants in the series. The device is designed for digitizing high-frequency signals where power efficiency and dynamic range are critical constraints.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2262-14 is a pin-compatible alternative offering 14-bit resolution. Other members of the LTC2262 family may share the same package but differ in resolution or speed specifications.
