AD9629BCPZRL7-40

Analog To Digital Converters (ADC) Overview

The AD9629BCPZRL7-40 is a monolithic, single-channel 12-bit analog-to-digital converter (ADC) from Analog Devices Inc. It operates at a maximum sampling rate of 40 MSPS with a differential input bandwidth of 700 MHz. The device utilizes a multistage differential pipeline architecture and features an on-chip voltage reference and sample-and-hold circuit. It requires a 1.8 V analog supply and supports digital output driver supplies ranging from 1.7 V to 3.6 V. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 71.3 dBFS at a 9.7 MHz input frequency and a Spurious-Free Dynamic Range (SFDR) of 95 dBc under the same conditions. Power consumption is specified at 85 mW when operating at the maximum 80 MSPS rate.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix RL7 indicates reel packaging by consulting the manufacturer's official ordering guide. Confirm that the BC designation corresponds to the industrial temperature range specifications (-40°C to +85°C). Ensure compatibility with the required DRVDD voltage levels for your target logic family before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption alongside high dynamic range performance at moderate sampling rates. The separate DRVDD supply allows flexibility in interfacing with various logic families. Consider the internal clock divider options if system clock frequencies do not match the desired conversion rate directly.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9629 series, which includes variants operating at 20 MSPS, 65 MSPS, and 80 MSPS. The AD9629 is pin-compatible with the AD9609 (10-bit) and AD9649 (14-bit) ADCs, facilitating migration paths between different resolution requirements within the same package footprint.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same package and pinout include the AD9629BCPZ-20, AD9629BCPZ-65, and AD9629BCPZ-80. Verify that the alternative speed grade meets the system's timing requirements and that power dissipation characteristics remain within thermal limits.
