Analog Devices Inc. AD9626BCPZRL7-250

Overview

AD9626BCPZRL7-250 from Analog Devices is a 12-bit, 250 MSPS analog-to-digital converter optimized for wideband communications and radar subsystems. It delivers 64.8 dBFS SNR at 70 MHz input, 80 dBc SFDR, and 10.5 ENOB with 1.8 V single-supply operation, integrated track-and-hold, on-chip reference, and CMOS output interface.

For engineers reviewing the AD9626BCPZRL7-250 datasheet, AD9626BCPZRL7-250 pinout, AD9626BCPZRL7-250 application, or AD9626BCPZRL7-250 equivalent, key selection criteria include sampling rate scalability (170/210/250 MSPS variants), input bandwidth (700 MHz), power efficiency (364 mW @ 250 MSPS), and programmable data format support (offset binary, twos complement, Gray code).

Technical Context

The AD9626BCPZRL7-250 employs a pipelined switched-capacitor ADC architecture with digital error correction logic and a front-end differential sample-and-hold amplifier. Sampling occurs on the rising edge of the differential clock input, supporting CMOS/LVDS/LVPECL clock signaling.

It features dual-output modes: single-port CMOS output at up to 250 MHz or interleaved dual-port mode at 125 MHz per port, with integrated clock duty cycle stabilizer and data capture clock (DCO+/DCO−) for timing alignment. The analog input is self-biased to ~1.4 V common-mode voltage with 4.3 kΩ differential input resistance and 2 pF capacitance.

FAQ

What is the maximum analog input frequency supported by the AD9626BCPZRL7-250?

The AD9626BCPZRL7-250 has a full-power analog bandwidth of 700 MHz, meaning it can accurately digitize signals with fundamental frequencies up to 700 MHz while maintaining specified SNR and SFDR performance. This enables direct RF sampling in L-band and S-band applications without intermediate frequency conversion stages, and is verified per AC specifications in the datasheet under conditions of −1.0 dBFS input at 25°C.

Does the AD9626BCPZRL7-250 require external reference components?

No, the AD9626BCPZRL7-250 integrates a precision voltage reference and does not require external decoupling capacitors or reference ICs. The on-chip reference establishes the 1.25 V p-p full-scale span for the 12-bit ADC core and is programmable via SPI to adjust input range between 1.0 V and 1.5 V p-p, simplifying system design and improving board-level reliability.

What output data formats does the AD9626BCPZRL7-250 support?

The AD9626BCPZRL7-250 supports three programmable output data formats: offset binary (default), twos complement, and Gray code-all selectable via its serial port interface (SPI). This flexibility allows direct compatibility with various FPGA logic families and DSP architectures without external format translation logic, reducing gate count and timing uncertainty in high-speed digital interfaces.

How does the power consumption of the AD9626BCPZRL7-250 scale with sample rate?

The AD9626BCPZRL7-250 consumes 364 mW at its maximum 250 MSPS rate, 310 mW at 210 MSPS, and 272 mW at 170 MSPS in single-port mode. Power scales approximately linearly with sample rate due to pipelined architecture clocking, enabling dynamic power optimization in systems where throughput can be reduced during low-activity periods without sacrificing signal fidelity.

Is the AD9626BCPZRL7-250 pin-compatible with other members of the AD962x family?

Yes, the AD9626BCPZRL7-250 shares identical pinout and package (56-lead LFCSP) with the AD9625 (LVDS output variant) and AD9627 (dual-channel version), enabling hardware reuse across performance tiers. However, it is not pin-compatible with the 10-bit AD9601 family-despite marketing language about "pin-compatible family," the AD9601 uses a different pin assignment and smaller package, requiring PCB redesign for substitution.
