Product details
Overview
AD9433BSVZ-125 from Analog Devices is a 12-bit, 125 MSPS analog-to-digital converter optimized for IF sampling up to 350 MHz, featuring 67.7 dB SNR at 125 MSPS with 49.3 MHz input, 72 dBc SFDR at 150 MHz, and 750 MHz full-power analog bandwidth. It integrates on-chip track-and-hold, reference, clock duty cycle stabilization, and SFDR optimization circuitry, and is deployed in cellular infrastructure receivers and broadband wireless base stations.
For engineers reviewing the AD9433BSVZ-125 datasheet, AD9433BSVZ-125 pinout, AD9433BSVZ-125 application, or AD9433BSVZ-125 equivalent, key selection considerations include its 125 MSPS sampling rate, differential analog input range of 2 V p-p, dual-supply operation (5 V analog / 3.3 V digital), SFDR mode control via dedicated pin, and industrial temperature range (−40°C to +85°C) in a 52-lead TQFP_EP package.
Technical Context
The AD9433BSVZ-125 employs a pipeline ADC architecture with integrated track-and-hold and on-chip 2.5 V reference, supporting differential encode clock inputs (PECL-compatible) and user-selectable output formats (twos complement or offset binary). Its SFDR optimization circuit is controlled by the SFDR MODE pin and improves spurious performance across dc–70 MHz.
It operates with separate analog (VCC = 5 V) and digital (VDD = 3.3 V) supplies, delivers TTL/CMOS-compatible outputs, and features an overrange (OR) flag. The exposed thermal pad must be soldered to ground for thermal reliability and signal integrity in high-frequency IF sampling systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - defines quantization step size and dynamic range for digitizing wideband IF signals |
| Max Sampling Rate | 125 MSPS - supports Nyquist sampling of signals up to 62.5 MHz or undersampling of IFs up to 350 MHz |
| SNR @ 125 MSPS | 67.7 dB at fIN = 49.3 MHz - determines minimum detectable signal level in noise-limited receivers |
| SFDR @ 125 MSPS | 72 dBc at fIN = 150 MHz - limits spurious content in multicarrier WCDMA/LTE front ends |
| Analog Bandwidth | 750 MHz - enables faithful capture of harmonics and wideband modulated waveforms without attenuation |
| Power Dissipation | 1.35 W typical at 125 MSPS - requires thermal management via exposed pad soldering and PCB copper area |
| Differential Input Range | 2 V p-p - sets full-scale voltage swing for matched transformer or balun interface design |
Pinout & Package
The AD9433BSVZ-125 is housed in a 52-lead thin quad flat package with exposed thermal pad (TQFP_EP, SV-52-2), specified for −40°C to +85°C operation. The exposed paddle must be soldered to the PCB ground plane to ensure thermal reliability and minimize jitter.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed IF sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9432BSVZ-105 | 12-bit, 105 MSPS max; identical pinout and package; lower power (1.275 W); reduced SFDR at >70 MHz | Best suited for cost-sensitive 3G single-carrier receivers where 125 MSPS is not required | Select when system sampling rate budget allows relaxation to 105 MSPS and thermal constraints are tighter |
| AD9628BCPZ-105 | 12-bit, 105 MSPS; JESD204B serial output; smaller 48-lead LFCSP; no on-chip reference; higher SNR (69.5 dB) | Preferred for space-constrained, FPGA-connected designs needing reduced trace count and lower EMI | Choose when migrating to serial interface architecture and board real estate is constrained |
Compared with AD9432BSVZ-105, AD9433BSVZ-125 delivers 20 MSPS higher throughput and superior SFDR above 100 MHz; versus AD9628BCPZ-105, it offers parallel CMOS outputs and integrated reference but requires more PCB area and routing resources.

FAQ
What is the maximum analog input frequency supported by the AD9433BSVZ-125?
The AD9433BSVZ-125 supports IF sampling up to 350 MHz, as confirmed in its General Introduction and Product Highlights sections. This capability enables undersampling of cellular, LMDS, and radar IF signals without requiring analog pre-filtering or downconversion. The 750 MHz full-power analog bandwidth ensures minimal amplitude roll-off across this range, preserving signal integrity for wideband modulation schemes.
Does the AD9433BSVZ-125 require an external reference voltage?
No, the AD9433BSVZ-125 includes an on-chip 2.5 V reference (VREFOUT) with ±0.1 V tolerance, eliminating the need for an external reference in most applications. VREFIN can accept an external 2.5 V source if higher precision or temperature stability is required, but the internal reference is sufficient for standard IF sampling use cases such as 3G multicarrier receivers and cable monitoring systems.
How does the SFDR MODE pin affect performance of the AD9433BSVZ-125?
The SFDR MODE pin on the AD9433BSVZ-125 enables a proprietary on-chip circuit that optimizes spurious-free dynamic range. When pulled high (5 V), it improves SFDR by up to 11 dBc-e.g., from 72 dBc to 83 dBc at 70 MHz-by dynamically compensating for transfer function nonlinearities. This mode is recommended for multicarrier and wideband applications where discrete spurs limit system dynamic range.
What is the power supply configuration required for the AD9433BSVZ-125?
The AD9433BSVZ-125 requires two independent supplies: 5 V (±2.5%) on VCC pins for the analog core and 3.3 V (±10%) on VDD pins for digital outputs. These must be decoupled locally with 0.1 μF ceramic capacitors. The exposed thermal pad must be soldered to ground to meet thermal specifications (θJA = 16°C/W at 1 m/s airflow) and ensure stable 1.35 W operation at 125 MSPS.
Is the AD9433BSVZ-125 pin-compatible with other members of the AD943x family?
Yes, the AD9433BSVZ-125 is explicitly stated to be pin-compatible with the AD9432, sharing identical footprint, pinout, and package (52-lead TQFP_EP). This allows drop-in replacement in existing AD9432-based designs to upgrade sampling rate from 105 MSPS to 125 MSPS without PCB revision, provided thermal and power delivery margins accommodate the higher 1.35 W dissipation.
