AD9627BCPZ-105

Analog To Digital Converters (ADC) Overview

The AD9627BCPZ-105 is a dual-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 105 MSPS. It utilizes a multistage differential pipelined architecture with integrated output error correction logic. The device features wide bandwidth differential sample-and-hold inputs supporting user-selectable input ranges from 1 V p-p to 2 V p-p. Power consumption is specified at 657 mW with a sine wave input and DRVDD at 1.8 V, or up to 740 mW with DRVDD at 3.3 V. The analog supply voltage (AVDD) and digital core supply (DVDD) operate at 1.8 V, while the digital output driver supply (DRVDD) supports 1.8 V CMOS/LVDS or 3.3 V CMOS levels. It includes an internal voltage reference, clock duty cycle stabilizer, and serial port interface for configuration.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCPZ' against the manufacturer's current ordering guide to confirm package type and lead time specifications. Ensure that the required DRVDD voltage level matches your system design, as the component supports both 1.8 V and 3.3 V digital output supplies. Confirm availability through authorized distributors, as stock levels fluctuate.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a dual-channel 12-bit resolution is required at sampling rates up to 105 MSPS. Consider the power consumption requirements, which vary based on the selected DRVDD voltage and load conditions. Verify that the analog input frequency does not exceed the 650 MHz bandwidth specification. Ensure compatibility with the desired digital interface standards, either CMOS or LVDS, before finalizing the design.

Analog To Digital Converters (ADC) Part Context

The AD9627 series encompasses multiple speed grades, including 80 MSPS, 105 MSPS, 125 MSPS, and 150 MSPS variants. The BCPZ suffix indicates a 64-lead LFCSP package. This component is part of a family designed for communications applications where low cost, small size, and versatility are prioritized. It shares pin compatibility with other devices in the Analog Devices portfolio for migration purposes.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the AD9627BCPZ-80, AD9627BCPZ-125, and AD9627BCPZ-150, depending on the required sampling rate. For different resolutions, consider the AD9640 (14-bit), AD9627-11 (11-bit), or AD9600 (10-bit), noting that these offer pin compatibility for migration.
