AD9683BCPZRL7-170

Analog To Digital Converters (ADC) Overview

The AD9683BCPZRL7-170 is a 14-bit Analog-to-Digital Converter (ADC) from Analog Devices, operating at a maximum sampling rate of 170 MSPS. It features a multistage differential pipelined architecture with integrated output error correction logic and an internal voltage reference. The device utilizes a JESD204B serial interface supporting lane rates up to 5 Gbps and includes an on-chip PLL for clock generation. It operates from a single 1.8 V supply, supports flexible analog input ranges from 1.4 V p-p to 2.0 V p-p, and incorporates a duty cycle stabilizer. The component is housed in a 32-lead LFCSP package and functions within an industrial temperature range of −40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix corresponds to the required 170 MSPS performance level when ordering. Confirm that the BCPZ packaging variant matches the target PCB footprint requirements. Ensure the RL7 reel specification aligns with automated assembly capabilities. Cross-reference the revision history for any updates to register maps or timing parameters before finalizing design documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring a balance of high resolution and moderate sampling speeds. The integrated JESD204B interface reduces board routing complexity compared to parallel interfaces. Consider the internal reference and PLL features if minimizing external component count is a priority. Verify that the 1.8 V supply requirement fits within the system's power budget constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9683 family of high-speed ADCs designed for communications and broadband data applications. The family includes variants with different maximum sampling rates, such as the 250 MSPS version. All members share the same 32-lead LFCSP package and functional block diagram, differing primarily in their specified conversion rates and associated AC performance metrics.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9683BCPZ-170 is the standard equivalent part number for this component. Other speed grades within the AD9683 series may be compatible if the lower sampling rate meets system requirements.
