AD9627BCPZ11-150

Analog To Digital Converters (ADC) Overview

The AD9627BCPZ11-150 is a dual, 11-bit analog-to-digital converter (ADC) operating at sampling rates up to 150 MSPS. It features a multistage differential pipelined architecture with integrated output error correction logic and wide bandwidth differential sample-and-hold inputs. The device supports flexible analog input ranges from 1 V p-p to 2 V p-p and includes an internal voltage reference. Digital outputs are configurable for 1.8 V to 3.3 V CMOS or 1.8 V LVDS operation. Key performance metrics include an SNR of 65.7 dBc to 70 MHz at 150 MSPS and an SFDR of 84 dBc. Power consumption is 820 mW at maximum speed.

Analog To Digital Converters (ADC) Feature Summary

• Dual 11-bit ADC cores with 105 MSPS/150 MSPS sampling rates
• Integrated duty cycle stabilizer and internal voltage reference
• Configurable digital outputs: 1.8 V–3.3 V CMOS or 1.8 V LVDS
• Fast detect/threshold bits and composite signal monitor for AGC

Analog To Digital Converters (ADC) Applications

• Diversity radio systems
• Multimode digital receivers (3G)
• I/Q demodulation systems
• Smart antenna systems
• General-purpose software radios

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '11' indicates the 11-bit variant of the AD9627 family. Confirm the package type is 64-lead LFCSP (CP-64-3). Ensure compatibility with the required supply voltages: AVDD/DVDD at 1.8 V nominal and DRVDD between 1.8 V and 3.3 V depending on the selected output interface mode.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 11-bit resolution is sufficient for the application, offering pin compatibility with the 10-bit AD9600, 12-bit AD9627, and 14-bit AD9640 for migration purposes. Consider the 150 MSPS rate if higher IF sampling frequencies up to 450 MHz are required using the integer 1-to-8 clock divider. Evaluate power constraints, as standby power is 77 mW and power-down power is 6 mW.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9627-11 series, which is a derivative of the broader AD9627 family. While the standard AD9627 offers 12-bit resolution, the AD9627-11 provides 11-bit resolution. The BC in the model name denotes the commercial temperature range extension to industrial (-40°C to +85°C), and PZ indicates the lead-free LFCSP package.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible replacements within the same package include the AD9627 (12-bit), AD9640 (14-bit), and AD9600 (10-bit). These allow for simple migration between different resolution requirements without changing the PCB layout.
