AD7774KN

ADCs/DACs - Special Purpose Overview

The AD7774KN is a high-speed, low-power analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features four independent channels with a resolution of 12 bits and supports sampling rates up to 500 kSPS per channel. The device utilizes a successive approximation register (SAR) architecture and accepts single-ended inputs. It operates with a 5 V analog supply and a separate digital supply, typically 3.3 V or 5 V. The part is housed in a 48-lead LFCSP package and is designed for applications requiring simultaneous multi-channel acquisition with parallel data output interfaces.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix KN against the official Analog Devices datasheet to confirm package type and temperature range. Ensure compatibility with existing board layouts regarding the 48-lead LFCSP footprint. Check for any recent lifecycle notices or obsolescence warnings directly from the manufacturer before procurement planning.

ADCs/DACs - Special Purpose Selection Notes

Select this component when four synchronized 12-bit conversions are required at moderate speeds. Compare power dissipation figures against system thermal constraints. Verify that the parallel interface timing requirements align with the host microcontroller or FPGA capabilities. Consider the input voltage range relative to sensor outputs.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AD777x family of high-speed, low-power ADCs from Analog Devices. The family includes variants with different resolutions and channel counts, such as the AD7773 and AD7775. The AD7774 specifically targets applications needing four channels of 12-bit performance.

ADCs/DACs - Special Purpose Replacement Considerations

Check for direct pin-compatible replacements within the AD777x series, such as the AD7773 or AD7775, depending on whether channel count or resolution adjustments are acceptable. Verify electrical parameter equivalence for critical specifications like SNR and power consumption.
