Product details
Overview
AD9269BCPZ-20 from Analog Devices is a dual-channel, 16-bit, 20 MSPS analog-to-digital converter operating from a single 1.8 V analog supply with 2 Vp-p differential input, integrated voltage reference, and on-chip quadrature error correction (QEC). 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 and diversity radio systems.
For engineers reviewing the AD9269BCPZ-20 datasheet, AD9269BCPZ-20 pinout, AD9269BCPZ-20 application, or AD9269BCPZ-20 equivalent, key selection criteria include guaranteed no missing codes over −40°C to +85°C, 700 MHz analog input bandwidth, programmable clock divider (1-to-6), DCO-aligned CMOS outputs, and SPI-configurable QEC for direct-conversion receiver calibration.
Technical Context
The AD9269BCPZ-20 employs a multistage differential pipeline architecture with output error correction logic to ensure 16-bit accuracy and no missing codes across temperature. Its sample-and-hold circuit maintains performance up to 200 MHz input frequency while supporting differential clock inputs compliant with CMOS, LVDS, or LVPECL standards.
Integrated QEC corrects dc offset, gain, and phase mismatches between channels using SPI-programmable coefficients. The device features a duty cycle stabilizer (DCS), programmable digital test pattern generation, and configurable data output multiplexing - all optimized for complex signal processing in battery-powered and portable instrumentation.
Key Specifications

FAQ
What is the maximum analog input frequency supported by the AD9269BCPZ-20?
The AD9269BCPZ-20 supports analog input frequencies up to 200 MHz while maintaining specified SNR and SFDR performance. Its 700 MHz analog input bandwidth ensures minimal attenuation and phase distortion for signals within the first three Nyquist zones, making it suitable for undersampling RF applications in radar and spectrum analysis.
Does the AD9269BCPZ-20 require an external voltage reference?
No, the AD9269BCPZ-20 includes an on-chip 1.0 V voltage reference with ±12 mV tolerance over temperature. It also supports external reference input via the VREF pin, allowing users to override the internal reference for improved accuracy or custom full-scale ranges - both configurations are fully supported in the AD9269BCPZ-20 datasheet.
How does the quadrature error correction (QEC) function in the AD9269BCPZ-20?
The AD9269BCPZ-20 implements hardware-based QEC that measures and compensates for dc offset, gain, and phase mismatches between its two ADC channels using SPI-programmable coefficients. This correction occurs in real time and is essential for achieving >65 dB image rejection in zero-IF receivers - a capability confirmed in the AD9269BCPZ-20 functional block diagram and AC specifications table.
What digital output formats does the AD9269BCPZ-20 support?
The AD9269BCPZ-20 supports three programmable output data formats: offset binary, gray code, and twos complement - selected via SPI register or static pin configuration (SCLK/DFS). All formats are delivered on 16-bit parallel CMOS outputs with independent DCO timing, ensuring compatibility with FPGA, ASIC, and DSP interfaces across diverse signal processing architectures.
Is the AD9269BCPZ-20 pin-compatible with other Analog Devices ADCs?
Yes, the AD9269BCPZ-20 uses a 64-lead LFCSP (CP-64-17) package that is pin-compatible with the AD9268, AD9258, AD9251, AD9231, AD6659, and AD9204 families. This enables hardware reuse and migration paths between 10-bit and 16-bit converters sampling from 20 MSPS to 125 MSPS - explicitly stated in the AD9269BCPZ-20 product highlights section.
