Product details
Overview
AD9269BCPZ-80 from Analog Devices is a dual-channel, 16-bit, 80 MSPS analog-to-digital converter operating from a single 1.8 V analog supply with 700 MHz analog input bandwidth, 77.6 dBFS SNR at 9.7 MHz, and integrated quadrature error correction (QEC) for I/Q signal processing in direct-conversion receivers.
For engineers reviewing the AD9269BCPZ-80 datasheet, AD9269BCPZ-80 pinout, AD9269BCPZ-80 application, or AD9269BCPZ-80 equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial-temperature operation (−40°C to +85°C), LFCSP-64 package mapping, and two rigorously cross-checked alternative ADCs for diversity radio and ultrasound systems.
Technical Context
The AD9269BCPZ-80 employs a multistage differential pipeline architecture with output error correction logic to guarantee 16-bit accuracy and no missing codes across temperature. Its dual-channel design supports simultaneous sampling with matched gain/phase characteristics enabled by optional QEC.
It accepts differential clock inputs (CMOS/LVDS/LVPECL), features programmable 1-to-6 clock division, and provides independent DCO outputs per channel with <0.1 ns skew. The on-chip voltage reference (1.0 V ±12 mV) and sample-and-hold circuit support full-scale 2 V p-p analog inputs up to 200 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees monotonicity and no missing codes over −40°C to +85°C. |
| Sampling Rate | 80 MSPS - maximum conversion rate with full AC performance maintained. |
| SNR @ 9.7 MHz | 77.6 dBFS - enables high-fidelity digitization of narrowband RF signals in W-CDMA/LTE baseband. |
| SFDR @ 9.7 MHz | 93 dBc - suppresses spurious content critical for adjacent-channel rejection in multimode receivers. |
| Analog Input BW | 700 MHz - supports wideband IF sampling up to 200 MHz input frequency without external amplification. |
| Power @ 80 MSPS | 100 mW per channel (AVDD + DRVDD = 1.8 V) - enables low-power portable medical imaging and battery-powered instrumentation. |
| QEC Support | Integrated dc/gain/phase mismatch correction - eliminates need for external calibration in I/Q demodulation systems. |
Pinout & Package
The AD9269BCPZ-80 is housed in a 64-lead RoHS-compliant LFCSP (CP-64-17) with exposed paddle soldered to AGND for thermal and noise integrity.

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-80 | Same 64-lead LFCSP package and pinout; identical 16-bit/80 MSPS spec but lacks integrated QEC block. | Requires external calibration for I/Q imbalance correction; suitable where QEC is implemented in FPGA or DSP. | Select when system-level QEC is already available and cost reduction is prioritized over analog-domain correction. |
| AD9653BCPZ-125 | Higher 125 MSPS sampling rate; same 16-bit resolution and LFCSP-64 package; SNR 76.4 dBFS @ 9.7 MHz (slightly lower than AD9269BCPZ-80). | Targets wider instantaneous bandwidth applications (e.g., 40 MHz LTE carriers); higher power (140 mW/channel). | Select when sampling bandwidth exceeds 80 MSPS requirement and system can accommodate increased power and thermal load. |
Compared with AD9269BCPZ-80, AD9268BCPZ-80 offers identical speed and footprint but shifts QEC responsibility to the system processor, whereas AD9653BCPZ-125 trades 1.2 dB SNR for 45 MSPS extra bandwidth-making AD9269BCPZ-80 optimal for power-constrained, calibration-sensitive I/Q receivers.

FAQ
What is the maximum analog input frequency supported by the AD9269BCPZ-80?
The AD9269BCPZ-80 supports analog input frequencies up to 200 MHz while maintaining specified AC performance, enabled by its 700 MHz analog input bandwidth and patented sample-and-hold circuit. At 200 MHz input, SNR is 71 dBFS and SFDR is 80 dBc per the datasheet's AC specifications table.
Does the AD9269BCPZ-80 require an external voltage reference?
No, the AD9269BCPZ-80 includes an on-chip 1.0 V voltage reference with ±12 mV tolerance over temperature. It also supports external reference via the VREF pin, but internal reference operation is fully functional and commonly used to reduce BOM count and layout complexity.
How does the quadrature error correction (QEC) function in the AD9269BCPZ-80?
The AD9269BCPZ-80's QEC block corrects dc offset, gain mismatch, and phase skew between its two ADC channels using on-chip calibration logic. It operates in real time during normal conversion and is configurable via SPI-eliminating need for external calibration components in I/Q demodulation systems.
What digital output formats does the AD9269BCPZ-80 support?
The AD9269BCPZ-80 supports offset binary, gray code, and twos complement data formats, all selectable via SPI register configuration or hardware pins (SCLK/DFS). Format selection is independent per channel and applies to all 16 output bits (D0x–D15x).
Is the AD9269BCPZ-80 pin-compatible with other Analog Devices ADCs?
Yes, the AD9269BCPZ-80 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 migration paths across 10-bit to 16-bit, 20 MSPS to 125 MSPS ADC families.
