AD9265BCPZ-105

Analog To Digital Converters (ADC) Overview

The AD9265BCPZ-105 is a 16-bit, 105 MSPS analog-to-digital converter (ADC) utilizing a multistage differential pipelined architecture with integrated output error correction logic. It guarantees no missing codes across the full operating temperature range of −40°C to +85°C. The device operates from a single 1.8 V analog supply and a separate digital output driver supply supporting 1.8 V CMOS or LVDS outputs. Key performance metrics include a signal-to-noise ratio (SNR) of 79.0 dBFS at 70 MHz input frequency and 105 MSPS sampling rate, and a spurious-free dynamic range (SFDR) of 93 dBc under identical conditions. Power consumption is specified at 343 mW for DC input and 394 mW for sine wave input in CMOS mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '105' corresponds to the 105 MSPS conversion rate variant within the AD9265 family. Confirm package type is 48-lead LFCSP (CP-48-9) and check RoHS compliance status. Ensure the ordering code matches the exact speed grade required for the target application timing constraints.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 105 MSPS sampling rate are required for high-performance communication systems. Consider the 1.8 V supply requirement and available output interface options (CMOS vs. LVDS). Evaluate power consumption needs against the 394 mW typical draw in CMOS mode. Verify compatibility with existing clocking infrastructure given the integer 1-to-8 input clock divider capability.

Analog To Digital Converters (ADC) Part Context

The AD9265BCPZ-105 belongs to the AD9265 series of high-speed, low-power ADCs from Analog Devices. It shares pinout compatibility with the AD9255, facilitating migration between 16-bit and 14-bit resolutions. The device is designed for applications demanding high linearity and low power in a compact form factor, serving as a versatile solution for modern digital receiver architectures.

Analog To Digital Converters (ADC) Replacement Considerations
