Product details
Overview
AD9650BCPZ-25 from Analog Devices is a dual-channel, 16-bit, 25 MSPS analog-to-digital converter optimized for high-dynamic-range digitization of IF and baseband signals up to 300 MHz. It operates from a single 1.8 V analog supply, delivers 83 dBFS SNR at 9.7 MHz input, 95 dBc SFDR, and consumes only 119 mW per channel-enabling low-power, high-fidelity acquisition in medical ultrasound front-ends.
For engineers reviewing the AD9650BCPZ-25 datasheet, AD9650BCPZ-25 pinout, AD9650BCPZ-25 application, or AD9650BCPZ-25 equivalent, this page provides verified specifications, validated CMOS/LVDS pin mapping, confirmed industrial temperature operation (−40°C to +85°C), and real-world design context for instrumentation and spectral analysis systems.
Technical Context
The AD9650BCPZ-25 implements a multistage differential pipelined ADC architecture with integrated error correction logic and a duty cycle stabilizer that compensates for clock asymmetry-ensuring stable performance even with non-50% duty-cycle inputs. Its dual core shares a precision 1.35 V internal voltage reference and supports integer 1-to-8 clock division.
Differential analog inputs feature 500 MHz bandwidth and 2.7 V p-p full-scale range, while digital outputs are configurable as either parallel 16-bit CMOS or LVDS, each with programmable latency (12/12.5 cycles) and dedicated DCO timing signals. The SPI interface enables full configuration of data formatting, dither, power modes, and synchronization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit-guarantees no missing codes and supports ≥98 dB theoretical dynamic range for high-precision signal capture. |
| Sampling Rate | 25 MSPS-fixed maximum conversion rate for this variant, enabling Nyquist-limited bandwidth up to 12.5 MHz with oversampling capability. |
| SNR @ 9.7 MHz | 83 dBFS-measured at 25°C, indicating <1.5 LSB rms input-referred noise for clean digitization of low-amplitude RF/IF tones. |
| SFDR @ 9.7 MHz | 95 dBc-specifies spurious-free resolution critical for spectrum analysis where harmonic distortion must be suppressed below −90 dBc. |
| Power Consumption | 119 mW per channel-measured at 25 MSPS with 1.8 V CMOS outputs, enabling thermally constrained embedded designs without active cooling. |
| Analog Input Bandwidth | 500 MHz-supports direct sampling of wideband IF signals up to third Nyquist zone, reducing external filtering complexity. |
| Supply Voltages | AVDD = 1.8 V ±0.1 V, DRVDD = 1.8 V ±0.1 V-tight tolerance ensures stable reference and output driver operation across industrial temperature range. |
Pinout & Package
The AD9650BCPZ-25 is housed in a 64-lead LFCSP (Lead Frame Chip Scale Package) with exposed thermal pad requiring solder connection to PCB ground plane for proper thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+, CLK− | Differential ADC clock input | Accepts CMOS/LVDS/LVPECL; internal bias at 0.9 V enables robust clock reception with jitter immunity via duty cycle stabilizer. |
| VIN+A, VIN−A / VIN+B, VIN−B | Differential analog inputs (Ch A/B) | 500 MHz bandwidth, 2.7 V p-p full-scale range, 11 pF input capacitance-designed for transformer- or amplifier-driven IF interfaces. |
| D0A–D15A, D0B–D15B | Parallel digital outputs | 16-bit CMOS outputs (1.8 V) or LVDS pairs; MSB-aligned, with configurable interleaved or independent channel routing. |
| DCOA, DCOB | Data clock outputs | Source-synchronous timing references for FPGA/CPLD capture; skew-controlled to ≤±0.6 ns in CMOS mode. |
| CSB, SCLK/DFS, SDIO/DCS | SPI serial interface | 3-wire, 40 ns minimum SCLK period; supports register read/write for offset calibration, dither enable, and power-down control. |
| PDWN, OEB | Hardware control inputs | Asynchronous power-down (<2.5 mW) and output enable allow rapid system-level power gating without SPI interaction. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip dither option | Improves SFDR by >5 dB at low-input amplitudes-critical for detecting weak spectral components in chemical analysis applications. |
| Duty cycle stabilizer (DCS) | Compensates for clock duty cycle variation down to ±10%, eliminating need for external clock conditioning circuitry. |
| Flexible output interface | Single 1.8 V supply supports both CMOS and LVDS outputs-reducing BOM count and simplifying layout for mixed-signal FPGA interfaces. |
| Integer 1-to-8 clock divider | Enables use of higher-frequency, lower-jitter master clocks (e.g., 200 MHz) while maintaining precise 25 MSPS sampling rate. |
| Integrated voltage reference | 1.35 V ±14 mV internal reference eliminates external reference IC, saving space and improving drift stability over −40°C to +85°C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 16-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9268BCPZ-20 | 20 MSPS max, identical 16-bit resolution and LFCSP-64 package; lacks on-chip dither and has 81 dBFS SNR at 9.7 MHz. | Lower sampling rate limits usable bandwidth to 10 MHz; suitable only where reduced throughput suffices. | Select when cost sensitivity outweighs need for 25 MSPS or enhanced SFDR via dither. |
| ADS52J90IRGCT | Texas Instruments 16-bit, 40 MSPS dual ADC; requires separate 3.3 V digital supply and offers JESD204B serial output instead of parallel. | Higher speed but incompatible pinout and interface-requires FPGA redesign and new layout. | Choose only if migrating to high-speed serial interface and accepting increased power (380 mW total) and layout effort. |
Compared with AD9268BCPZ-20 and ADS52J90IRGCT, the AD9650BCPZ-25 uniquely balances 25 MSPS throughput, on-chip dither for spectral purity, and drop-in compatibility with existing AD92xx-family layouts-making it optimal for incremental upgrades in medical and test equipment.

FAQ
What is the maximum analog input frequency supported by the AD9650BCPZ-25?
The AD9650BCPZ-25 supports analog input frequencies up to 300 MHz, enabled by its 500 MHz differential input bandwidth and proprietary input architecture. This allows direct sampling of signals in the third Nyquist zone, making the AD9650BCPZ-25 suitable for IF digitization in software-defined radios and broadband test equipment without requiring external undersampling filters.
Does the AD9650BCPZ-25 require an external voltage reference?
No, the AD9650BCPZ-25 integrates a precision 1.35 V internal voltage reference with ±14 mV output voltage error over temperature. External reference is optional and only needed when higher absolute accuracy or custom reference voltage is required-otherwise, the AD9650BCPZ-25 operates fully self-contained with VREF and SENSE pins configured for internal mode.
Can the AD9650BCPZ-25 operate in LVDS output mode?
Yes, the AD9650BCPZ-25 supports both 1.8 V CMOS and LVDS digital output modes. In LVDS mode, it delivers ANSI-compliant differential outputs (290–400 mV VOD) with 1.15–1.35 V common-mode offset, and requires DRVDD = 1.8 V. Pin configuration differs between CMOS and LVDS modes-refer to Figures 6 and 7 in the AD9650BCPZ-25 datasheet for exact mappings.
What is the power consumption of the AD9650BCPZ-25 at 25 MSPS?
At 25 MSPS with 1.8 V CMOS outputs, the AD9650BCPZ-25 consumes 119 mW per channel (238 mW total), as specified in Table 1 under "Power Consumption." With 1.8 V LVDS outputs, total power rises to 355 mW due to higher driver current requirements-confirming the AD9650BCPZ-25's suitability for low-power portable instrumentation where thermal budget is constrained.
Is the AD9650BCPZ-25 pin-compatible with other members of the AD9650 family?
Yes, all AD9650 variants-including AD9650BCPZ-25, AD9650BCPZ-65, AD9650BCPZ-80, and AD9650BCPZ-105-share identical 64-lead LFCSP packaging and pinout. This allows hardware reuse across sampling rates; only firmware and clock configuration need adjustment when upgrading to higher-speed versions, preserving board layout and reducing qualification time for the AD9650BCPZ-25 and its siblings.
