Product details
Overview
AD9269BCPZ-65 from Analog Devices is a dual-channel, 16-bit, 65 MSPS analog-to-digital converter operating from a single 1.8 V analog supply with 2 Vp-p differential input range, integrated sample-and-hold and voltage reference, and 700 MHz analog input bandwidth. It delivers 77.6 dBFS SNR at 9.7 MHz input and supports offset binary, gray code, or twos complement output formats for I/Q demodulation in direct-conversion receivers.
For engineers reviewing the AD9269BCPZ-65 datasheet, AD9269BCPZ-65 pinout, AD9269BCPZ-65 application, or AD9269BCPZ-65 equivalent, key selection criteria include guaranteed no-missing-codes performance, quadrature error correction (QEC) for channel matching, programmable clock divider (1-to-6), data clock output (DCO) alignment, and RoHS-compliant 64-lead LFCSP packaging compatible with AD9268/AD9258 family migration paths.
Technical Context
The AD9269BCPZ-65 employs a multistage differential pipeline architecture with output error correction logic to achieve 16-bit accuracy at 65 MSPS while ensuring no missing codes across −40°C to +85°C. Its on-chip quadrature error correction block corrects dc offset, gain, and phase mismatches between channels-critical for complex signal processing in diversity radio systems.
Differential clock inputs accept CMOS/LVDS/LVPECL signals up to 480 MHz, with optional duty cycle stabilizer (DCS) maintaining performance under wide clock duty cycle variation. Digital outputs support 1.8 V to 3.3 V CMOS levels, multiplexed bus operation, and programmable data alignment via DCO timing control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees full-scale linearity and dynamic range suitable for high-fidelity baseband digitization in LTE/W-CDMA receivers. |
| Sample Rate | 65 MSPS - enables Nyquist-limited capture of signals up to 32.5 MHz without aliasing in undersampled RF applications. |
| SNR @ 9.7 MHz | 77.6 dBFS - provides >12.6 ENOB, sufficient for 16-QAM/64-QAM demodulation in multimode digital receivers. |
| Input Bandwidth | 700 MHz - supports direct RF sampling of IF signals up to 200 MHz with minimal amplitude roll-off. |
| Power Consumption | 101.2 mA AVDD current at 65 MSPS - translates to ~182 mW total power (AVDD + DRVDD), enabling battery-powered ultrasound and handheld scope meter designs. |
| Differential Nonlinearity | −0.5/+1.1 LSB (25°C) - ensures monotonicity and low harmonic distortion in precision measurement instrumentation. |
| Package | 64-lead LFCSP (9 mm × 9 mm, CP-64-17) - exposes thermal paddle for soldered AGND connection, achieving θJA = 23°C/W in still air for stable thermal management. |
Pinout & Package
The AD9269BCPZ-65 is housed in a 64-lead RoHS-compliant LFCSP (CP-64-17) with exposed paddle soldered to PCB analog ground for thermal, noise, and mechanical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+, CLK− | Differential encode clock input | Accepts CMOS/LVDS/LVPECL; internal common-mode bias at 0.9 V enables robust clock reception with jitter as low as 0.1 ps rms. |
| D0A–D15A / D0B–D15B | Channel A/B parallel digital outputs | 16-bit MSB-aligned CMOS outputs; configurable for offset binary, gray, or twos complement; support multiplexed bus sharing. |
| DCOA, DCOB | Data clock output per channel | Programmable edge alignment ensures reliable latching by external FPGA/ASIC; supports 1.8 V or 3.3 V logic levels. |
| VIN+A/VIN−A, VIN+B/VIN−B | Differential analog inputs | 700 MHz bandwidth, 2 Vp-p full-scale range, 6.5 pF input capacitance - optimized for transformer- or balun-coupled RF/IF interfaces. |
| AVDD (Pins 49,50,53,54,59,60,63,64) | Analog supply | Eight 1.8 V pins reduce IR drop and noise coupling; require local 100 nF + 10 µF decoupling per group per datasheet layout guidelines. |
| DRVDD (Pins 10,19,28,37) | Digital output driver supply | Independent 1.8 V to 3.3 V rail allows interfacing with mixed-voltage logic families without level shifters. |
| SDIO/DCS, SCLK/DFS, CSB | SPI serial interface control | Three-wire SPI (CSB/SCLK/SDIO) configures QEC, DCO alignment, output format, and power modes; DCS pin doubles as static enable in non-SPI mode. |
| PDWN, OEB | Power and output enable | PDWN high enters 1 mW power-down state; OEB low enables outputs, high places them in high-impedance for shared-bus arbitration. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated quadrature error correction (QEC) | Corrects inter-channel dc offset, gain, and phase mismatch in real time-enabling coherent I/Q sampling without external calibration in smart antenna systems. |
| Programmable 1-to-6 clock divider | Allows use of higher-frequency, lower-jitter master clocks while maintaining precise 65 MSPS sampling rate-reducing clock generation complexity and EMI. |
| Built-in deterministic test pattern generation | Supports BIST via SPI-loaded patterns (pseudorandom, custom, ramp), eliminating need for external signal sources during production test and field diagnostics. |
| Data clock output (DCO) with programmable alignment | Adjusts DCO edge relative to data edges in 125 ps steps-compensating for PCB trace skew and ensuring setup/hold compliance with downstream logic. |
| Optional duty cycle stabilizer (DCS) | Maintains ADC performance even with 30%–70% clock duty cycle variation-tolerating imperfect clock sources in cost-sensitive portable medical imaging platforms. |

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-65 | Same 64-lead LFCSP package and pinout; identical 16-bit/65 MSPS spec but lacks integrated QEC and DCS; lower power (165 mW vs. 182 mW). | Best suited for cost-sensitive applications where inter-channel calibration is handled externally or not required. | Select AD9268BCPZ-65 when QEC is unnecessary and board space/power budget is constrained. |
| AD9653BCPZ-125 | Higher 125 MSPS sample rate; same 16-bit resolution and LFCSP package; requires 3.3 V AVDD (not 1.8 V); no QEC; higher power (320 mW). | Targeted at wideband spectrum analysis and high-speed data acquisition where >65 MSPS is mandatory. | Choose AD9653BCPZ-125 only if sample rate >65 MSPS is required and 3.3 V analog supply is available. |
Compared with AD9269BCPZ-65, AD9268BCPZ-65 offers identical speed and footprint without QEC-reducing cost and power but requiring external calibration-while AD9653BCPZ-125 trades 1.8 V operation and QEC for higher speed and wider bandwidth, increasing power and supply complexity.

FAQ
What is the maximum analog input frequency supported by the AD9269BCPZ-65?
The AD9269BCPZ-65 features a 700 MHz analog input bandwidth, enabling faithful digitization of signals up to 200 MHz with measured SNR of 71 dBFS. This makes it suitable for undersampling IF signals in GSM, W-CDMA, and LTE receivers without requiring external bandpass filtering prior to the ADC input stage.
Does the AD9269BCPZ-65 support simultaneous sampling of both channels with matched latency?
Yes, the AD9269BCPZ-65 provides true simultaneous sampling with identical pipeline latency of 9 cycles (11 cycles when QEC is active) for both Channel A and Channel B. The shared differential clock (CLK+/CLK−) and SYNC input ensure deterministic inter-channel timing alignment critical for I/Q demodulation and beamforming applications.
Can the AD9269BCPZ-65 operate with a 3.3 V digital output supply?
Yes, the AD9269BCPZ-65 supports DRVDD from 1.8 V to 3.3 V, allowing direct interfacing with 3.3 V CMOS logic without level shifters. At DRVDD = 3.3 V, output high-level voltage is ≥3.25 V (IOH = 0.5 mA), and low-level voltage is ≤0.2 V (IOL = 1.6 mA), meeting standard 3.3 V logic thresholds.
How does the quadrature error correction (QEC) block function in the AD9269BCPZ-65?
The QEC block in the AD9269BCPZ-65 performs real-time correction of dc offset, gain, and phase mismatches between Channel A and Channel B using internal calibration registers accessible via SPI. It operates continuously during normal conversion and improves image rejection by >30 dB in direct-conversion receiver architectures without external calibration circuitry.
Is the AD9269BCPZ-65 pin-compatible with other members of the AD92xx family?
Yes, the AD9269BCPZ-65 uses the same 64-lead LFCSP (CP-64-17) package and pinout as the AD9268, AD9258, AD9251, AD9231, AD6659, and AD9204-enabling hardware reuse and simplified migration across 10-bit to 16-bit, 20 MSPS to 125 MSPS performance tiers within the same PCB footprint.
