Product details
Overview
AD9432BSVZ-80 from Analog Devices is a 12-bit, 80 MSPS monolithic pipeline analog-to-digital converter with on-chip track-and-hold, 500 MHz analog bandwidth, 2.0 V p-p differential input range, and 3.3 V CMOS/TTL-compatible digital outputs. It operates from a single 5.0 V analog supply and supports base station zero-IF sampling and HDTV broadcast camera digitization.
For engineers reviewing the AD9432BSVZ-80 datasheet, AD9432BSVZ-80 pinout, AD9432BSVZ-80 application, or AD9432BSVZ-80 equivalent, this page delivers verified specifications, validated package mapping (TQFP_EP), confirmed pin functions, real-world dynamic performance at 80 MSPS, and two rigorously cross-checked alternative ADCs for communications-grade sampling systems.
Technical Context
The AD9432BSVZ-80 implements a switched-capacitor pipeline architecture with on-chip track-and-hold and integrated 2.5 V reference (VREFOUT). Its differential analog input accepts ±1 V signals with 3.0 V common-mode bias, and its encode interface supports both differential and single-ended TTL/CMOS clocking with 4.0 ns minimum pulse width.
Digital outputs use twos complement coding, deliver 10-cycle pipeline latency, and feature separate VDD (3.3 V) and DGND pins to isolate digital switching noise. The device achieves 67 dB SNR and 80 dB SFDR at 49 MHz input frequency when sampled at 105 MSPS - performance maintained down to 80 MSPS per the BSVZ-80 speed grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - delivers 4096 discrete output codes for high-fidelity signal capture in wideband receivers. |
| Maximum Conversion Rate | 80 MSPS - fixed speed grade; supports Nyquist sampling of up to 40 MHz baseband signals without aliasing. |
| Analog Bandwidth | 500 MHz - enables accurate digitization of IF signals up to 250 MHz without front-end filtering degradation. |
| SNR @ 49 MHz AIN | 67 dB - measured at 105 MSPS but guaranteed ≥65.5 dB at 80 MSPS; defines usable dynamic range for RF subsystems. |
| Power Dissipation | 790–1000 mW - typical 850 mW at 105 MSPS; scales downward at 80 MSPS, enabling thermal management in dense PCB layouts. |
| Digital Output Interface | 3.3 V CMOS/TTL - compatible with FPGA I/O banks and ASIC logic without level-shifting; requires separate VDD pin. |
| Input Voltage Range | 2.0 V p-p differential - corresponds to ±1.0 V swing across AIN/AIN; sets full-scale gain for transformer or op-amp driver design. |
Pinout & Package
AD9432BSVZ-80 is packaged in a 52-lead thin quad flat package with exposed thermal pad (TQFP_EP, SV-52-2), optimized for industrial temperature operation (−40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,3,4,9,11,33–35,38–40,43,48,51) | Analog Ground | Reference plane for analog circuitry; must be isolated from digital ground except at single-point star connection. |
| VCC (Pins 2,5,6,10,36,37,42,44,47,52) | Analog Supply | 5.0 V ±5% input powering internal reference, track-and-hold, and core ADC; requires local 0.1 µF decoupling. |
| ENCODE / ENCODE (Pins 7,8) | Differential Clock Input | ADC samples on rising edge of ENCODE; supports 4.0 ns min pulse width; VIHD ≤3.5 V limits direct PECL drive. |
| AIN / AIN (Pins 49,50) | Differential Analog Input | Accepts ±1.0 V differential signal with 3.0 V common-mode; 4 pF input capacitance demands low-impedance driver. |
| VREFOUT / VREFIN (Pins 46,45) | Internal Reference Output/Input | VREFOUT = 2.5 V ±0.1 V; VREFIN bypassed to GND with 0.1 µF capacitor to stabilize reference for full-scale accuracy. |
| D11–D0 (Pins 15–20,25–30) | 12-bit Twos Complement Data | MSB-first parallel output; D11 (Pin 15) to D0 (Pin 30); timing referenced to ENCODE edge with 5.5–8.0 ns propagation delay. |
| OR (Pin 14) | Out-of-Range Flag | Active-high signal indicating D11–D0 = +2047 or −2048; synchronized to data pipeline latency (10 cycles) for real-time clipping detection. |
| VDD / DGND (Pins 13,22,23,32 / 12,21,24,31) | Digital Output Supply/Ground | 3.3 V (2.7–3.6 V) power domain for outputs; DGND separation prevents digital noise coupling into analog section. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip track-and-hold + reference | Eliminates need for external THA or precision voltage reference ICs, reducing BOM count and layout area in compact RF modules. |
| 500 MHz analog bandwidth | Supports direct sampling of L-band and S-band IF signals (e.g., 2.1 GHz cellular IF at 140 MHz), avoiding image-reject filter complexity. |
| Twos complement output format | Enables seamless interfacing with DSP/FPGA arithmetic units without sign-extension logic or post-processing conversion. |
| Separate analog/digital supplies | Allows independent power rail sequencing and noise isolation - critical for maintaining >65 dB SNR in mixed-signal baseband boards. |
| Out-of-range (OR) flag | Provides cycle-accurate overrange detection for automatic gain control (AGC) loop feedback without requiring external comparators or FPGA logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9432BSVZ-105 | Same die, rated for 105 MSPS max; higher SNR (67.5 dB) and SFDR (80 dB) at 49 MHz input; 1100 mW max power. | Required for systems needing >80 MSPS sampling (e.g., 5G NR sub-6 GHz IF digitization). | Select AD9432BSVZ-105 only if design requires >80 MSPS; AD9432BSVZ-80 offers lower power and cost for fixed 80 MSPS systems. |
| AD9235BRUZ-80 | 12-bit, 80 MSPS, but uses 3.3 V analog supply; no on-chip reference; 370 mW typical power; 450 MHz analog BW. | Suitable for low-power portable instrumentation where external reference and driver are already present. | Choose AD9235BRUZ-80 for battery-powered test gear; AD9432BSVZ-80 preferred for telecom infrastructure needing integrated reference and higher analog BW. |
Compared with AD9432BSVZ-105, the AD9432BSVZ-80 trades 25 MSPS headroom and marginal SNR for 150 mW lower typical power and lower cost; versus AD9235BRUZ-80, it adds integrated reference and 50 MHz higher analog bandwidth at the expense of higher supply voltage and power.

FAQ
What is the maximum analog input frequency supported by the AD9432BSVZ-80?
The AD9432BSVZ-80 has a specified analog bandwidth of 500 MHz, meaning it maintains flat frequency response up to that point. For Nyquist-compliant sampling, the maximum fundamental input frequency is 40 MHz at 80 MSPS. However, the device supports bandpass undersampling of IF signals up to 250 MHz using its 500 MHz analog bandwidth - confirmed in Figure 8 of the Rev. F datasheet.
Does the AD9432BSVZ-80 require an external reference voltage?
No. The AD9432BSVZ-80 includes an on-chip 2.5 V reference (VREFOUT) that can be directly connected to VREFIN via a short trace and bypassed with a 0.1 µF capacitor to GND. External references are optional only for applications requiring tighter than ±0.1 V tolerance or adjustable full-scale range.
Can the AD9432BSVZ-80 interface directly with a 3.3 V FPGA I/O bank?
Yes. The AD9432BSVZ-80 provides 3.3 V CMOS/TTL-compatible digital outputs (D11–D0, OR) powered by its dedicated VDD pin (2.7–3.6 V). When VDD = 3.3 V, output logic levels meet FPGA I/O thresholds without level shifters - verified in Table 1 under "Digital Outputs" section.
What is the function of the OR (Out-of-Range) pin on the AD9432BSVZ-80?
The OR pin (Pin 14) asserts high whenever the ADC output code equals +2047 or −2048 - indicating positive or negative full-scale saturation. It is pipeline-synchronized (10-cycle latency) and remains asserted until the next in-range sample, enabling real-time AGC or clipping detection in baseband processors without additional logic.
Is the AD9432BSVZ-80 pin-compatible with the AD9432BSVZ-105?
Yes. Both AD9432BSVZ-80 and AD9432BSVZ-105 share identical 52-lead TQFP_EP packaging, pinout, and footprint (SV-52-2). They differ only in speed grade rating and AC performance specifications - making them drop-in replacements where 105 MSPS capability is not required.
