AD9629BCPZ-65

Analog To Digital Converters (ADC) Overview

The AD9629BCPZ-65 is a monolithic, single-channel 12-bit analog-to-digital converter (ADC) from Analog Devices Inc. It operates with a 1.8 V analog supply and supports digital logic voltages between 1.7 V and 3.6 V. The device features a multistage differential pipeline architecture with output error correction to ensure no missing codes across the full operating temperature range of -40°C to +85°C. It samples at a rate of 65 MSPS with a 700 MHz analog input bandwidth. Key electrical specifications include a signal-to-noise ratio (SNR) of 71.3 dBFS at a 9.7 MHz input frequency and a spurious-free dynamic range (SFDR) of 95 dBc under the same conditions. Power consumption is rated at 85 mW when operating at maximum speed.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CPZ' indicates the lead-free RoHS-compliant LFCSP package variant. Confirm that the '-65' designation strictly corresponds to the 65 MSPS sampling grade within the AD9629 family. Ensure compatibility with the required 1.8 V analog supply and appropriate digital driver voltage levels before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 65 MSPS throughput are required alongside low power consumption. Consider the AD9629BCPZ-40 or AD9629BCPZ-80 if different sampling rates better match the system requirements. Evaluate the need for the internal voltage reference versus an external precision reference based on noise performance goals.

Analog To Digital Converters (ADC) Part Context

The AD9629BCPZ-65 belongs to the AD9629 series of 12-bit ADCs, which also includes variants operating at 20 MSPS, 40 MSPS, and 80 MSPS. These devices share pinout compatibility with the AD9609 (10-bit) and AD9649 (14-bit) converters, facilitating design migration across different resolution and speed requirements within the same package footprint.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same package include the AD9629BCPZ-20, AD9629BCPZ-40, and AD9629BCPZ-80. Verify that the alternative sampling rate meets the application's Nyquist requirements and that power dissipation characteristics remain within thermal limits.
