AD9627BCPZ-80

Analog To Digital Converters (ADC) Overview

The AD9627BCPZ-80 is a dual-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 80 MSPS. It features a multistage differential pipelined architecture with integrated output error correction logic and wide bandwidth sample-and-hold amplifiers. The device operates on a single 1.8 V analog supply and supports flexible digital output drivers ranging from 1.8 V to 3.3 V CMOS or 1.8 V LVDS. Key performance specifications include an SNR of 69.5 dBc at 70 MHz input frequency and an SFDR of 85 dBc under the same conditions. Power consumption is rated at 490 mW for DC input and up to 657 mW during sine wave operation.

• User-configurable serial port interface supporting data formatting options and built-in self-test capabilities.

Analog To Digital Converters (ADC) Applications

• Diversity radio systems
• Multimode digital receivers including GSM, EDGE, WCDMA, CDMA2000, WiMAX, and TD-SCDMA
• I/Q demodulation systems
• Smart antenna systems
• General-purpose software radios

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCPZ corresponds to the LFCSP-64 package configuration required for your design. Confirm that the -80 speed grade meets the system timing requirements, as this variant is limited to 80 MSPS compared to higher-speed options in the family. Ensure the ordering documentation matches the Rev. B datasheet specifications for accuracy.

Analog To Digital Converters (ADC) Selection Notes

Select the AD9627BCPZ-80 when a lower sampling rate than the 125 MSPS or 150 MSPS variants is sufficient for the application. This model offers reduced power consumption compared to faster versions while maintaining identical architectural features. Consider the available output driver voltage levels (CMOS vs. LVDS) to match the receiving logic family without additional translation circuitry.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9627 series of dual 12-bit ADCs, which also includes variants optimized for 105 MSPS, 125 MSPS, and 150 MSPS speeds. The series shares pin compatibility with the AD9640, AD9627-11, and AD9600, facilitating migration between different resolution and speed requirements within the same package footprint.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9627ABCPZ-80 serves as a direct functional replacement within the same package and specification envelope. For applications requiring higher throughput, the AD9627BCPZ-125 or AD9627BCPZ-150 are compatible upgrades. Lower resolution alternatives like the AD9600 may be considered if cost reduction is prioritized over dynamic range.
