AD9633BCPZ-80

Analog To Digital Converters (ADC) Overview

The AD9633BCPZ-80 is a quad-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices. It features an on-chip sample-and-hold circuit and operates at a maximum conversion rate of 80 MSPS. The device utilizes a single 1.8 V power supply for both analog and digital domains. Key electrical specifications include a signal-to-noise ratio (SNR) of 71.7 dBFS at 9.7 MHz input frequency and a spurious-free dynamic range (SFDR) of 96 dBc under the same conditions. Differential nonlinearity (DNL) is typically ±0.3 LSB, while integral nonlinearity (INL) is typically ±0.5 LSB. The ADC provides serial LVDS outputs compliant with ANSI-644 standards.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Applications

• Medical ultrasound systems
• High-speed imaging equipment
• Quadrature radio receivers
• Diversity radio receivers
• Test and measurement instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCPZ corresponds to the RoHS-compliant lead-free 48-lead LFCSP package variant. Confirm that the -80 designation strictly limits the maximum sampling rate to 80 MSPS, distinguishing it from higher-speed variants in the family. Ensure compatibility with the required 1.8 V supply rails and LVDS interface requirements before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a four-channel solution is required within a small footprint. The AD9633BCPZ-80 is suitable for applications prioritizing low power and ease of integration over ultra-high speed. Consider the pin-compatible AD9253 if a 14-bit resolution upgrade path is needed without changing the PCB layout. Evaluate the 650 MHz analog bandwidth against the specific Nyquist zone requirements of the target application.

Analog To Digital Converters (ADC) Part Context

The AD9633 belongs to a family of high-performance, low-power serial LVDS ADCs designed for space-constrained environments. It shares architectural similarities with other Analog Devices converters but is distinct in its quad-channel configuration and 12-bit resolution. The device is optimized for applications requiring multiple simultaneous channels with synchronized operation.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9253 is a pin-compatible alternative offering 14-bit resolution. Other variants within the AD9633 family, such as the AD9633BCPZ-105 and AD9633BCPZ-125, offer higher sampling rates but may require verification of thermal performance and power supply stability.
