Product details
Overview
AD9231BCPZRL7-80 from Analog Devices is a dual-channel, 12-bit, 80 MSPS analog-to-digital converter operating from a single 1.8 V analog supply with 1.8 V to 3.3 V digital output drivers. It features a 700 MHz analog input bandwidth, 71.3 dBFS SNR at 9.7 MHz input, and ±0.40 LSB DNL - enabling high-fidelity digitization in I/Q demodulation and ultrasound front-ends.
For engineers reviewing the AD9231BCPZRL7-80 datasheet, AD9231BCPZRL7-80 pinout, AD9231BCPZRL7-80 application, or AD9231BCPZRL7-80 equivalent, key selection criteria include its 80 MSPS sampling rate, differential clock support (CMOS/LVDS/LVPECL), programmable data format (offset binary/gray/twos complement), and on-chip voltage reference with 1.0 V nominal output.
Technical Context
The AD9231BCPZRL7-80 implements a multistage differential pipeline architecture with output error correction logic to guarantee 12-bit accuracy and no missing codes across −40°C to +85°C. Its patented sample-and-hold circuit maintains performance up to 200 MHz input frequency while supporting 2 Vp-p differential analog inputs referenced to 0.9 V common-mode voltage.
Digital interface flexibility includes SPI-configurable clock/data alignment, integer 1-to-8 input clock divider, optional duty cycle stabilizer, and multiplexed CMOS outputs with independent DCO timing per channel. Power management features include standby mode (37 mW) and power-down mode (2.2 mW).

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 12-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9258BCPZ-65 | 14-bit resolution, 65 MSPS max, same 64-lead LFCSP package and pinout | Higher resolution but lower speed; requires higher analog input drive capability due to increased effective number of bits | Select when ENOB >12.5 bits is required at ≤65 MSPS, leveraging identical layout and firmware adaptation. |
| AD9204BCPZ-80 | 10-bit resolution, 80 MSPS max, same package and pin-compatible footprint | Lower resolution and reduced SFDR (85 dBc vs. 93 dBc); optimized for cost-sensitive, lower-dynamic-range applications | Choose for simplified signal chain design where 10-bit precision suffices and power budget is tighter (58 mW vs. 141.8 mW at 80 MSPS). |
Compared with AD9231BCPZRL7-80, AD9258BCPZ-65 trades speed for resolution and dynamic range, while AD9204BCPZ-80 sacrifices linearity and SNR for lower cost and power - making AD9231BCPZRL7-80 the optimal balance for 12-bit, 80 MSPS communications and medical imaging systems.

FAQ
What is the maximum analog input frequency supported by the AD9231BCPZRL7-80?
The AD9231BCPZRL7-80 supports analog input frequencies up to 200 MHz while maintaining specified AC performance, including 69.0 dBFS SNR and 83 dBc SFDR. This is enabled by its 700 MHz analog input bandwidth and patented sample-and-hold circuit, making it suitable for IF sampling in broadband receivers. The AD9231BCPZRL7-80 achieves this performance with a 2 Vp-p differential input and 1.0 V internal reference.
Does the AD9231BCPZRL7-80 require an external voltage reference?
No, the AD9231BCPZRL7-80 integrates a precision 1.0 V voltage reference with ±1.2% output tolerance and 2 mV load regulation error, eliminating the need for an external reference in most applications. It also supports external reference operation via the VREF pin if tighter accuracy or custom reference levels are required. The AD9231BCPZRL7-80's internal reference is factory-trimmed and stable over temperature.
How does the duty cycle stabilizer (DCS) function in the AD9231BCPZRL7-80?
The AD9231BCPZRL7-80's duty cycle stabilizer (DCS) dynamically corrects wide variations in input clock duty cycle - from 30% to 70% - while preserving aperture jitter below 0.1 ps rms. It operates transparently in the signal path and is enabled via the SDIO/DCS pin or SPI register. The AD9231BCPZRL7-80 maintains full AC specifications even with highly asymmetric clock waveforms, reducing clock generation complexity.
What digital output formats does the AD9231BCPZRL7-80 support?
The AD9231BCPZRL7-80 supports three configurable digital output formats: offset binary, gray code, and twos complement - selected via SPI or static pin control (SCLK/DFS). All formats deliver 12-bit parallel CMOS outputs per channel, with programmable alignment between data and DCO edges. The AD9231BCPZRL7-80 ensures deterministic timing regardless of format choice, supporting seamless integration with Xilinx and Intel FPGAs.
Is the AD9231BCPZRL7-80 pin-compatible with other members of the AD92xx family?
Yes, the AD9231BCPZRL7-80 uses a 64-lead LFCSP package that is pin-compatible with the AD9268 (16-bit), AD9258 (14-bit), AD9251 (14-bit), and AD9204 (10-bit) - enabling hardware reuse across resolution and speed grades. This migration path simplifies design scaling without PCB redesign. The AD9231BCPZRL7-80 shares identical pin functions for analog inputs, clock, power, and digital I/O with these devices.
