Product details
Overview
AD9231BCPZ-40 from Analog Devices is a dual-channel, 12-bit, 40 MSPS analog-to-digital converter operating from a single 1.8 V analog supply with 2 Vp-p differential input, 71.3 dBFS SNR at 9.7 MHz, and 93 dBc SFDR - deployed in I/Q demodulation systems for LTE and W-CDMA baseband receivers.
For engineers reviewing the AD9231BCPZ-40 datasheet, AD9231BCPZ-40 pinout, AD9231BCPZ-40 application, or AD9231BCPZ-40 equivalent, key selection criteria include its 40 MSPS sampling rate, 700 MHz analog input bandwidth, on-chip voltage reference, programmable clock divider (1-to-8), and CMOS/LVDS-compatible differential clock interface.
Technical Context
The AD9231BCPZ-40 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 supports full-performance operation up to 200 MHz input frequency.
Dual-channel synchronization is managed via a shared differential clock (CLK+/CLK−) and optional SYNC input for clock divider alignment. Digital outputs support offset binary, gray code, or twos complement format with programmable DCO/data alignment and multiplexed bus capability.

FAQ
What is the maximum analog input frequency supported by the AD9231BCPZ-40?
The AD9231BCPZ-40 supports analog input frequencies up to 200 MHz while maintaining specified SNR and SFDR performance, enabled by its 700 MHz analog input bandwidth and patented sample-and-hold circuit. This allows undersampling of IF signals in the second and third Nyquist zones for direct-conversion receiver architectures.
Does the AD9231BCPZ-40 require an external voltage reference?
No, the AD9231BCPZ-40 integrates a precision 1.0 V voltage reference with ±1.5% tolerance over temperature. It can operate in internal reference mode using VREF and SENSE pins, eliminating the need for external reference components unless higher accuracy or custom reference voltage is required.
Can the AD9231BCPZ-40 interface directly with 3.3 V logic systems?
Yes, the AD9231BCPZ-40 supports 1.8 V to 3.3 V digital output driver supply (DRVDD). When DRVDD = 3.3 V, its D0A–D11A and D0B–D11B outputs meet 3.3 V CMOS voltage levels, enabling direct connection to FPGAs or ASICs without level-shifting circuitry.
How is channel synchronization achieved in the AD9231BCPZ-40?
Channel synchronization in the AD9231BCPZ-40 is achieved through a shared differential clock (CLK+/CLK−) and a dedicated SYNC input that aligns the internal 1-to-8 clock divider across both ADC cores. This ensures deterministic phase relationship between Channel A and Channel B sampling instants.
What power savings does the AD9231BCPZ-40 offer in power-down mode?
In power-down mode (PDWN = high), the AD9231BCPZ-40 consumes only 2.2 mW total - a reduction of >97% versus its 71 mW per channel active power at 40 MSPS. Wake-up time from power-down is 350 µs, making it suitable for burst-mode acquisition in portable instruments.
