AD9627ABCPZ-105

Analog To Digital Converters (ADC) Overview

The AD9627ABCPZ-105 is a dual-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices. It supports sampling rates up to 105 MSPS with a differential pipelined architecture. The device operates on a single 1.8 V analog supply and features flexible digital output drivers supporting 1.8 V to 3.3 V CMOS or 1.8 V LVDS standards. Key performance metrics include an SNR of 69.4 dBc at 70 MHz input frequency and an SFDR of 85 dBc under the same conditions. Power consumption is rated at 650 mW for DC input and 740 mW for sine wave input at maximum speed. It includes an internal voltage reference, clock duty cycle stabilizer, and serial port interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A' against official documentation to confirm package type and temperature grade. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the ordering code matches the required sampling rate variant within the AD9627 family. Check RoHS compliance status prior to final procurement decisions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel solution is required for communication infrastructure. The 105 MSPS rate suits applications needing moderate bandwidth with high linearity. Consider the available output driver options (CMOS vs. LVDS) based on system interconnect requirements. Evaluate the power budget against the specified consumption values at the target operating frequency.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9627 family of dual 12-bit ADCs, which also includes variants supporting 80 MSPS, 125 MSPS, and 150 MSPS speeds. The family shares pin compatibility with other devices like the AD9640 and AD9600, facilitating migration between different resolution and speed requirements in existing designs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the AD9627ABCPZ-80, AD9627ABCPZ-125, and AD9627ABCPZ-150. These parts share identical pinouts and functionality but differ in maximum sampling rates. Verify that the alternative speed meets the application's Nyquist requirements.
