Product details
Overview
AD9269BCPZ-40 from Analog Devices is a dual-channel, 16-bit, 40 MSPS analog-to-digital converter (ADC) operating from a single 1.8 V analog supply with separate 1.8–3.3 V digital output drivers. It delivers 77.6 dBFS SNR at 9.7 MHz input and 71 dBFS at 200 MHz, supports differential 700 MHz analog input bandwidth, integrates quadrature error correction (QEC), and is specified for industrial temperature range (−40°C to +85°C). It serves in I/Q demodulation systems for LTE and W-CDMA receivers.
For engineers reviewing the AD9269BCPZ-40 datasheet, AD9269BCPZ-40 pinout, AD9269BCPZ-40 application, or AD9269BCPZ-40 equivalent, key selection considerations include its 40 MSPS sampling rate, dual-channel 16-bit resolution with guaranteed no missing codes, integrated QEC for direct-conversion receiver alignment, and LFCSP-64 package compatibility with AD9268/AD9258 family members.
Technical Context
The AD9269BCPZ-40 employs a multistage differential pipeline architecture with output error correction logic to achieve 16-bit accuracy at 40 MSPS while ensuring no missing codes across −40°C to +85°C. Its sample-and-hold circuit maintains performance up to 200 MHz input frequency and supports 2 V p-p differential analog input with 0.9 V common-mode voltage.
It features an optional SPI-configurable quadrature error correction (QEC) block that corrects dc offset, gain, and phase mismatch between channels-critical for complex baseband signal processing. Clocking is handled via differential CLK+/CLK− inputs supporting CMOS/LVDS/LVPECL, with programmable 1-to-6 integer division and duty cycle stabilizer (DCS) option.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees full-scale linearity and no missing codes over industrial temperature range. |
| Sampling Rate | 40 MSPS - fixed maximum conversion rate for this variant; enables real-time digitization of IF signals up to ~20 MHz Nyquist bandwidth. |
| SNR @ 9.7 MHz | 77.6 dBFS - defines dynamic range for narrowband communication signals; sufficient for high-fidelity I/Q sampling in LTE/W-CDMA. |
| SFDR @ 9.7 MHz | 93 dBc - indicates spurious-free performance critical for detecting weak signals adjacent to strong interferers in diversity radio systems. |
| Analog Input BW | 700 MHz - supports wideband RF sampling and direct IF digitization without external anti-alias filtering below 350 MHz. |
| Power @ 40 MSPS | 121.7 mW (DC input) / 136.3 mW (sine wave) - low power enables battery-powered handheld scope meters and portable ultrasound. |
| Differential Nonlinearity | −0.5/+1.1 LSB (25°C) - ensures monotonicity and minimal code-width variation for precision measurement applications. |
Pinout & Package
The AD9269BCPZ-40 is housed in a 64-lead RoHS-compliant LFCSP (CP-64-17) package with exposed paddle soldered to AGND for thermal and noise integrity. Pin count and layout are identical to AD9268, AD9258, AD9251, AD9231, AD6659, and AD9204-enabling drop-in migration across 10–16-bit, 20–125 MSPS ADC families.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+, CLK− | Differential clock input | Accepts CMOS/LVDS/LVPECL; enables jitter-insensitive sampling with aperture uncertainty of 0.1 ps rms. |
| D0A–D15A, D0B–D15B | Channel A/B parallel digital outputs | 16-bit MSB-first CMOS outputs; support offset binary/gray/twos complement format; multiplexable onto shared bus. |
| DCOA, DCOB | Data clock outputs | Programmable timing-aligned clocks for latch synchronization with FPGA/ASIC receivers; reduces setup/hold margin requirements. |
| VIN+A/VIN−A, VIN+B/VIN−B | Differential analog inputs | 700 MHz bandwidth; 2 V p-p full-scale range; 6.5 pF input capacitance; require matched 50 Ω termination for optimal SFDR. |
| AVDD (Pins 49,50,53,54,59,60,63,64) | Analog supply | Eight 1.8 V pins minimize IR drop and PSRR sensitivity; must be decoupled locally with 100 nF + 10 µF per pair. |
| DRVDD (Pins 10,19,28,37) | Digital output driver supply | Configurable 1.8–3.3 V; sets output logic levels independently of analog domain-enables direct interface to 1.8 V or 3.3 V FPGAs. |
| SDIO/DCS, SCLK/DFS, CSB | SPI serial interface | 3-wire SPI (CSB/SCLK/SDIO) for runtime configuration of QEC, clock divider, data format, DCO alignment, and power modes. |
| PDWN, OEB | Power and output control | PDWN high enters 1 mW power-down mode; OEB low enables outputs, high places them in high-impedance state for bus sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated quadrature error correction (QEC) | Corrects inter-channel dc offset, gain, and phase mismatch in real time-eliminates need for external calibration in I/Q receivers. |
| Programmable clock/data alignment | Adjusts DCO-to-data skew (±1 ns resolution) and data edge placement-simplifies timing closure with high-speed FPGA receivers. |
| Built-in deterministic test pattern generation | Supports BIST via SPI: ramp, checkerboard, pseudo-random, and custom user-defined patterns-enables production test without external signal sources. |
| Duty cycle stabilizer (DCS) | Compensates for asymmetric clock duty cycles (e.g., from PLLs or dividers) while maintaining <0.1 ps rms jitter-preserves SNR/SFDR. |
| Flexible digital output interface | Offset binary/gray/twos complement formatting + 1.8 V/3.3 V CMOS drive + multiplexed bus option-reduces PCB layer count and FPGA pin usage. |

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-40 | Same 64-lead LFCSP package and pinout; identical 16-bit/40 MSPS spec but lacks integrated QEC block. | Requires external calibration for I/Q imbalance correction; suitable where QEC is implemented digitally in FPGA. | Select AD9269BCPZ-40 when analog-domain QEC is needed to reduce FPGA resource usage and improve real-time stability. |
| AD9656BCPZ-40 | 16-bit, 40 MSPS, but single-channel only; uses same LFCSP-64 package but different pin mapping (no Channel B signals). | Not suitable for simultaneous I/Q sampling; requires two devices for dual-path operation-increasing cost, power, and board area. | Choose AD9269BCPZ-40 for space-constrained designs needing true dual-channel correlation without inter-device skew. |
Compared with AD9268BCPZ-40, the AD9269BCPZ-40 adds hardware QEC-reducing system-level calibration overhead-while compared with AD9656BCPZ-40, it provides native dual-channel synchronization and lower total BOM cost per I/Q path.

FAQ
What is the maximum analog input frequency supported by the AD9269BCPZ-40?
The AD9269BCPZ-40 supports analog input frequencies up to 200 MHz while maintaining specified AC performance-including 71 dBFS SNR and 80 dBc SFDR. Its 700 MHz small-signal analog input bandwidth ensures minimal roll-off and phase distortion below this limit, making it suitable for direct IF sampling in broadband receivers.
Does the AD9269BCPZ-40 require an external reference voltage?
No-the AD9269BCPZ-40 includes an on-chip 1.0 V voltage reference with ±12 mV tolerance over temperature. External reference is optional via the VREF pin; using the internal reference simplifies layout and reduces BOM count while delivering 77.6 dBFS SNR at 9.7 MHz.
How does the quadrature error correction (QEC) function in the AD9269BCPZ-40?
The AD9269BCPZ-40's QEC block corrects dc offset, gain, and phase mismatches between Channel A and Channel B in real time using internal calibration registers. Enabled via SPI, it operates continuously during normal conversion-improving image rejection ratio by >40 dB without external DSP or calibration routines.
What digital output formats does the AD9269BCPZ-40 support?
The AD9269BCPZ-40 supports offset binary, gray code, and twos complement data formats-all selectable via SPI register or hardware pins (SCLK/DFS). Format choice affects FPGA logic complexity: offset binary simplifies DC-coupled signal handling, while gray code minimizes metastability during clock domain crossing.
Is the AD9269BCPZ-40 pin-compatible with other Analog Devices ADCs?
Yes-the AD9269BCPZ-40 uses the same 64-lead LFCSP (CP-64-17) footprint and pinout as AD9268, AD9258, AD9251, AD9231, AD6659, and AD9204. This enables hardware reuse and migration across 10–16-bit, 20–125 MSPS ADC families without PCB redesign.
