AD9641BCPZ-155

Analog To Digital Converters (ADC) Overview

The AD9641BCPZ-155 is a single-channel, 14-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 155 MSPS. It utilizes a multistage differential pipelined architecture with integrated output error correction logic and features JESD204A coded serial digital outputs. The device operates from a single 1.8 V supply, consuming 313 mW at full speed. Key performance metrics include an SNR of 72.8 dBFS at 70 MHz input frequency and an SFDR of 90 dBc under the same conditions. It supports IF sampling frequencies up to 250 MHz and includes a programmable internal voltage reference.

Analog To Digital Converters (ADC) Feature Summary

• JESD204A coded serial digital outputs reduce board routing requirements and lower pin count for receiving devices.
• Multistage differential pipelined architecture with integrated output error correction logic ensures high linearity.
• Flexible analog input range allows user-selectable spans from 1.4 V p-p to 2.1 V p-p.
• Integrated duty cycle stabilizer compensates for clock variations to maintain excellent performance.

Analog To Digital Converters (ADC) Applications

• Communications systems including GSM, EDGE, W-CDMA, LTE, CDMA2000, WiMAX, and TD-SCDMA.
• Diversity radio systems and smart antenna configurations.
• Multimode digital receivers supporting 3G and 4G standards.
• General-purpose software radios and broadband data applications.
• Ultrasound equipment requiring high-speed digitization.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific -155 speed grade suffix matches system timing requirements. Check RoHS compliance documentation for environmental regulations. Ensure proper ESD handling procedures are followed during receipt and storage due to moisture sensitivity classification.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a single-channel ADC with 155 MSPS throughput is required. Compare against the AD9641-80 variant if lower power consumption at reduced speeds is prioritized over maximum bandwidth. Consider the dual-channel AD9644 family if synchronized multi-channel acquisition is necessary for the design.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9641 series of high-speed serial output ADCs. It shares architectural similarities with the AD9644 but differs in channel count. The -155 suffix specifically denotes the 155 MSPS speed bin, distinct from the 80 MSPS version. It is designed for compact form factors using the 32-lead LFCSP package.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9641BCPZ-80 serves as a lower-speed alternative within the same package and pinout. For dual-channel requirements, the AD9644BCPZ-155 offers comparable performance across two inputs. Verify pin compatibility and thermal characteristics before substituting any cross-model variants.
