AD9641BCPZRL7-80

Analog To Digital Converters (ADC) Overview

The AD9641BCPZRL7-80 is a single-channel, 14-bit analog-to-digital converter (ADC) operating at an 80 MSPS sampling rate. It features a JESD204A coded serial digital output interface and operates from a single 1.8 V supply. The device utilizes a multistage differential pipelined architecture with integrated output error correction logic. Key electrical specifications include a signal-to-noise ratio (SNR) of 73.7 dBFS at 70 MHz input frequency, a spurious-free dynamic range (SFDR) of 94 dBc, and power consumption of 238 mW. It supports flexible analog input ranges from 1.4 V p-p to 2.1 V p-p and includes a programmable internal voltage reference.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging configuration when sourcing components. Confirm that the -80 speed grade matches the required 80 MSPS conversion rate for the target application design. Ensure compatibility with the 32-lead LFCSP package dimensions during PCB layout planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component for designs requiring a single-channel 14-bit ADC with serial output capabilities. The 80 MSPS speed grade is suitable for intermediate frequency sampling up to 250 MHz. Consider the 238 mW power consumption at this speed grade against thermal constraints in the final enclosure.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9641 family of high-speed serial output ADCs. The -80 designation indicates the 80 MSPS speed bin, distinct from the 155 MSPS variant. The BCPZ suffix denotes the lead-free LFCSP package type compliant with RoHS standards.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9641BCPZ-80 is the tray-packaged equivalent of this reel-delivered component. Both share identical electrical specifications and functionality within the 80 MSPS speed grade.

Analog To Digital Converters (ADC) FAQ

What is the maximum analog input frequency supported by the AD9641?

The usable full-scale bandwidth is 250 MHz, although the analog input bandwidth parameter specifies a -3 dB input bandwidth of 780 MHz.

How does the device handle clock duty cycle variations?

An integrated ADC clock duty cycle stabilizer (DCS) compensates for variations in the ADC clock duty cycle, allowing the converter to maintain excellent performance.

What control interface is used for setup and configuration?

Programming for setup and control is accomplished using a 3-wire SPI-compatible serial interface.
