AD9629BCPZRL7-65

Analog To Digital Converters (ADC) Overview

The AD9629BCPZRL7-65 is a monolithic, single-channel 12-bit analog-to-digital converter (ADC) from Analog Devices Inc. It operates at a sampling rate of 65 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 (AVDD range: 1.7 V to 1.9 V) and supports digital driver supplies (DRVDD) 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. The component is housed in a 32-lead LFCSP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix RL7 corresponds to the reel packaging format as specified by Analog Devices. Confirm the specific speed grade matches the required 65 MSPS conversion rate. Ensure the component is sourced from authorized distributors to guarantee authenticity and adherence to RoHS compliance standards.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 65 MSPS sampling rate is required alongside 12-bit resolution. The separate DRVDD supply allows compatibility with both 1.8 V and 3.3 V logic families. Consider the 700 MHz analog input bandwidth for wideband signal processing applications requiring low power consumption.

Analog To Digital Converters (ADC) Part Context

The AD9629 belongs to a family of low-power, 1.8 V ADCs available in multiple speed grades (20, 40, 65, and 80 MSPS). It shares pin compatibility with the AD9609 (10-bit) and AD9649 (14-bit) converters, facilitating design migration within the same package footprint while adjusting for bit depth and sampling speed requirements.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9629BCPZ-65 is the tray-packaged equivalent of this part number. Other speed grades within the AD9629 series may be considered if the sampling rate requirement differs.
