Product details
Overview
AD9231BCPZRL7-20 from Analog Devices is a dual-channel, 12-bit, 20 MSPS analog-to-digital converter operating from a single 1.8 V analog supply with 2 Vp-p differential input range, 71.3 dBFS SNR at 9.7 MHz, and DNL of ±0.40 LSB. It integrates on-chip voltage reference, sample-and-hold, and serial port interface, targeting I/Q demodulation and portable medical ultrasound systems.
For engineers reviewing the AD9231BCPZRL7-20 datasheet, AD9231BCPZRL7-20 pinout, AD9231BCPZRL7-20 application, or AD9231BCPZRL7-20 equivalent, this page delivers verified specifications, package mapping, functional pin roles, real-world use cases, and validated alternative options for diversity radio, smart antenna, and battery-powered instrumentation designs.
Technical Context
The AD9231BCPZRL7-20 employs 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 supports full-performance operation up to 200 MHz input frequency and 700 MHz analog input bandwidth.
Dual independent ADC channels share a differential clock input (CLK+/CLK−) compatible with CMOS/LVDS/LVPECL, and support programmable features including integer 1-to-8 clock division, duty cycle stabilization, data format selection (offset binary/gray/twos complement), and built-in deterministic test pattern generation via SPI.

FAQ
What is the maximum analog input frequency supported by the AD9231BCPZRL7-20?
The AD9231BCPZRL7-20 supports analog input frequencies up to 200 MHz while maintaining specified AC performance (e.g., 69.0 dBFS SNR). Its 700 MHz analog input bandwidth ensures minimal attenuation and phase distortion across this range, enabling direct sampling of IF signals in diversity radio systems without external amplification or filtering.
Does the AD9231BCPZRL7-20 require an external voltage reference?
No, the AD9231BCPZRL7-20 includes an on-chip 1.0 V voltage reference with ±12 mV tolerance (0.981 V to 1.005 V) and 2 mV load regulation error at 1.0 mA. External reference is optional via the VREF pin and used only when higher accuracy or custom reference voltage is needed-standard operation uses the internal reference.
How does the power consumption of the AD9231BCPZRL7-20 compare to higher-speed variants?
The AD9231BCPZRL7-20 consumes 32 mW per channel at 20 MSPS, significantly less than the AD9231BCPZRL7-80 (71 mW/channel at 80 MSPS). This 55% reduction enables longer battery life in handheld scope meters and portable ultrasound devices where full 80 MSPS capability is unnecessary.
Can the AD9231BCPZRL7-20 operate with a 3.3 V digital output supply?
Yes, the AD9231BCPZRL7-20 supports DRVDD from 1.8 V to 3.3 V, allowing CMOS output levels compatible with both 1.8 V and 3.3 V logic families. At DRVDD = 3.3 V, high-level output voltage is ≥3.25 V (IOH = 0.5 mA), ensuring robust noise margin when interfacing with FPGA or ASIC receivers.
Is the AD9231BCPZRL7-20 pin-compatible with other members of the AD9231 family?
Yes, the AD9231BCPZRL7-20 shares the same 64-lead LFCSP package and pinout with AD9231BCPZRL7-40, AD9231BCPZRL7-65, and AD9231BCPZRL7-80. It is also pin-compatible with AD9251, AD9258, AD9268, and AD9204-enabling hardware reuse and migration paths across 10-bit to 16-bit, 20 MSPS to 125 MSPS ADCs.
