AD9640BCPZ-105

Analog To Digital Converters (ADC) Overview

The AD9640BCPZ-105 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 105 MSPS. It features a multistage differential pipelined architecture with integrated output error correction logic and an internal voltage reference. The device supports flexible analog input ranges from 1 V p-p to 2 V p-p with a 650 MHz bandwidth. Digital outputs are configurable for 1.8 V to 3.3 V CMOS or 1.8 V LVDS operation. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 71.9 dB at 70 MHz input and a Spurious-Free Dynamic Range (SFDR) of 85 dBc. Power consumption is approximately 645 mW with a sine wave input at DRVDD = 1.8 V.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCPZ' against the manufacturer's current ordering guide to confirm package type and temperature range specifications. Ensure that the required sampling speed aligns with the 105 MSPS designation rather than other variants in the AD9640 family. Confirm RoHS compliance status through official documentation before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel 14-bit resolution is required for intermediate frequency sampling up to 105 MSPS. Consider the power consumption differences between CMOS and LVDS output modes based on system requirements. Evaluate the need for the integrated signal monitor and fast detect features if automatic gain control latency is a critical design constraint.

Analog To Digital Converters (ADC) Part Context

The AD9640BCPZ-105 belongs to the AD9640 family of high-speed data converters designed for communications applications. This series offers pin compatibility with lower-resolution devices like the AD9627 and AD9600, facilitating migration paths. The device is housed in a 64-lead LFCSP package suitable for compact board designs.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9640ABCPZ-105 serves as a direct functional replacement within the same family, differing primarily in temperature grade specifications. Other variants such as the AD9640BCPZ-80 or AD9640BCPZ-125 offer different sampling rates but maintain architectural similarities.
