Product details
Overview
AD9233BCPZ-125 from Analog Devices is a 12-bit, 125 MSPS analog-to-digital converter with 1.8 V analog supply, 650 MHz differential input bandwidth, and on-chip sample-and-hold amplifier. It delivers 69.5 dBc SNR at 70 MHz input and 85 dBc SFDR, supporting ultrasound imaging and IF sampling in communications receivers.
For engineers reviewing the AD9233BCPZ-125 datasheet, AD9233BCPZ-125 pinout, AD9233BCPZ-125 application, or AD9233BCPZ-125 equivalent, key selection criteria include sampling rate stability at 125 MSPS, low 395 mW power consumption, differential clock interface compatibility (LVDS/CMOS/LVPECL), and industrial temperature range (−40°C to +85°C) operation.
Technical Context
The AD9233BCPZ-125 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 differential sample-and-hold amplifier supports full-scale input frequencies up to 225 MHz with flexible 1 V p-p to 2 V p-p range selection.
A dedicated duty cycle stabilizer (DCS) maintains performance across wide clock pulse width variations, while serial port interface (SPI) enables runtime configuration of data format (offset binary/Gray/twos complement), DCS enable, and voltage reference mode - all without requiring external components.
Key Specifications

|---|---|
| Resolution | 12-bit - guarantees monotonicity and no missing codes over full industrial temperature range |
| Max Sampling Rate | 125 MSPS - enables Nyquist-limited digitization of signals up to 62.5 MHz or undersampling of IFs beyond 100 MHz |
| SNR @ 70 MHz | 69.5 dBc - supports high-fidelity signal capture in medical ultrasound and CDMA-One baseband processing |
| SFDR @ 70 MHz | 85 dBc - ensures clean spectral representation for multi-carrier WCDMA and IMT-2000 receiver front-ends |

FAQ
What is the maximum analog input frequency supported by the AD9233BCPZ-125?
The AD9233BCPZ-125 features a 650 MHz analog input bandwidth and maintains specified SNR/SFDR performance up to 225 MHz input frequency. At 170 MHz, it achieves 68.9 dBc SNR and 83.5 dBc SFDR; at 300 MHz, SNR degrades to 67.8 dBc. The device supports both Nyquist sampling and undersampling architectures.
Does the AD9233BCPZ-125 require an external voltage reference?
No, the AD9233BCPZ-125 includes an on-chip 1.0 V voltage reference with ±35 mV output voltage error over temperature. External reference mode is optional via the SENSE pin, but most designs use the internal reference to reduce component count and improve thermal stability.
What clock interface standards does the AD9233BCPZ-125 support?
The AD9233BCPZ-125 accepts differential clock inputs compliant with CMOS, LVDS, and LVPECL standards. The internal common-mode bias is fixed at 1.2 V, and the duty cycle stabilizer (DCS) corrects input duty cycle deviations from 40% to 60%, ensuring consistent aperture jitter performance.
How does the AD9233BCPZ-125 manage power consumption at 125 MSPS?
At 125 MSPS with DRVDD = 3.3 V, the AD9233BCPZ-125 consumes 395 mW total (236 mA AVDD + 17 mA DRVDD). Standby mode draws 40 mW, and power-down mode reduces consumption to 1.8 mW. Thermal resistance is 26.4°C/W (θJA) with proper exposed paddle soldering.
Is the AD9233BCPZ-125 pin-compatible with other members of the AD9233 family?
Yes, all AD9233 speed grades (AD9233BCPZ-80, AD9233BCPZ-105, AD9233BCPZ-125) share identical 48-lead LFCSP packaging and pinout. This allows hardware reuse across sampling rate requirements, with only firmware and clock source changes needed for migration.
