AD9627ABCPZ-80

Analog To Digital Converters (ADC) Overview

The AD9627ABCPZ-80 is a dual-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices Inc. It operates at a maximum sampling rate of 80 MSPS with a differential pipelined architecture. The device requires a 1.8 V analog supply and supports digital output supplies ranging from 1.8 V to 3.3 V for CMOS or 1.8 V for LVDS modes. 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 specified at 490 mW for DC input and up to 657 mW with a sine wave input at 1.8 V DRVDD. It features integrated sample-and-hold amplifiers, an internal voltage reference, and a duty cycle stabilizer.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A' against the manufacturer's current ordering guide to confirm package type and temperature grade specifications. Ensure that the required clock divider settings and power-down modes align with system power constraints. Confirm compatibility with the target digital interface voltage levels before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel solution is required for communications applications needing low cost and small size. Consider the 80 MSPS speed limit relative to the Nyquist frequency of the input signal. Evaluate the need for LVDS versus CMOS outputs based on the downstream processing interface requirements and noise immunity needs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9627 family of dual 12-bit ADCs, which also includes variants operating at 105 MSPS, 125 MSPS, and 150 MSPS. The AD9627 shares pin compatibility with the AD9640, AD9627-11, and AD9600, facilitating migration between different resolution and speed grades within the Analog Devices portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9627BCPZ-80 is listed as a related variant in revision history notes, though functional equivalence should be verified via the latest datasheet. Other speeds in the AD9627 series (105/125/150 MSPS) are pin-compatible but may require re-evaluation of timing and power budgets.
