Product details
Overview
AD9446BSVZ-100 from Analog Devices is a 16-bit, 100 MSPS monolithic pipeline analog-to-digital converter (ADC) with on-chip track-and-hold, optimized for baseband and IF sampling in instrumentation, MRI receivers, and radar systems. It delivers 79.7 dBFS SNR at 30 MHz input, 89 dBc SFDR, and 60 fsec rms aperture jitter, operating from 3.3 V and 5.0 V supplies with LVDS or CMOS outputs.
For engineers reviewing the AD9446BSVZ-100 datasheet, AD9446BSVZ-100 pinout, AD9446BSVZ-100 application, or AD9446BSVZ-100 equivalent, key selection criteria include guaranteed 100 MSPS sampling rate, differential 3.2 Vp-p input range, LVDS/CMOS output mode select, clock duty cycle stabilization, and out-of-range detection-critical for high-fidelity signal capture in medical imaging and broadband communications.
Technical Context
The AD9446BSVZ-100 implements a 16-bit pipeline ADC architecture with buffered analog inputs, internal trimmed 1.6 V reference (enabling 3.2 Vp-p full-scale), and programmable data format (offset binary or twos complement). Its clock duty cycle stabilizer (DCS) maintains performance across wide input clock duty cycle variations, while the 13-cycle pipeline latency ensures deterministic timing for synchronous digital processing.
It supports dual-supply operation (AVDD1 = 3.3 V, AVDD2 = 5.0 V) and separate digital output supply (DRVDD = 3.3 V), with independent analog/digital ground domains (AGND, DRGND) and an exposed heat sink soldered to AGND. The 100-lead TQFP/EP package integrates LVDS biasing via external 3.74 kΩ resistor and provides dedicated OR+ / OR− outputs for overrange indication.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees 65,536 distinct output codes with no missing codes across full temperature range. |
| Max Sampling Rate | 100 MSPS - enables Nyquist-limited digitization of signals up to 50 MHz without aliasing in baseband applications. |
| SNR @ 30 MHz | 79.7 dBFS - corresponds to ~13.2 ENOB, supporting high-fidelity acquisition in MRI and radar IF stages. |
| Aperture Jitter | 60 fsec rms - limits sampling uncertainty, preserving dynamic range for multi-MHz analog inputs. |
| Analog Input Range | 2.0–4.0 Vp-p differential - configurable via SENSE pin; default 3.2 Vp-p with internal 1.6 V reference. |
| Digital Outputs | LVDS (ANSI-644) or CMOS - selectable via OUTPUT MODE pin; LVDS reduces EMI and supports longer trace runs. |
| Power Supplies | 3.3 V (AVDD1/DRVDD) + 5.0 V (AVDD2) - decoupled dual-rail design isolates analog and digital noise domains. |
Pinout & Package
AD9446BSVZ-100 is housed in a Pb-free, 100-lead TQFP/EP (exposed pad) package, specified for −40°C to +85°C industrial operation. The exposed heat sink must be soldered to AGND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+, VIN− | Differential Analog Input | High-impedance buffered inputs accepting 2.0–4.0 Vp-p differential signals; common-mode voltage fixed at 3.5 V. |
| CLK+, CLK− | Differential Clock Input | LVPECL-compatible inputs requiring ≥0.2 V differential swing and 1.3–1.6 V common-mode; DCS MODE enables jitter reduction. |
| D0+ to D15+ | Data Output (True) | 16-bit parallel output bits; true/complement pairs (e.g., D0+, D0−) in LVDS mode; true-only in CMOS mode. |
| DCO+, DCO− | Data Clock Output | Source-synchronous LVDS clock aligned to data edges; essential for timing-critical FPGA/ASIC capture. |
| OR+, OR− | Out-of-Range Indicator | Differential flag signaling when input exceeds selected full-scale range-enables real-time signal clipping detection. |
| SENSE, VREF | Reference Configuration | SENSE = AGND selects internal 1.6 V reference (3.2 Vp-p input); VREF is I/O pin for external reference or trimming. |
| OUTPUT MODE | Output Logic Select | Low = CMOS (3.3 V), High = LVDS; determines drive strength, termination, and PCB routing requirements. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip track-and-hold with high input impedance | Eliminates need for external driver amplifiers in many IF sampling applications, reducing BOM and layout complexity. |
| Clock duty cycle stabilizer (DCS) | Compensates for clock asymmetry, maintaining SNR/SFDR performance even with 40%–60% duty cycle inputs. |
| Programmable data format (offset binary/twos complement) | DFS pin control allows seamless integration with DSP/FPGA logic without external bit manipulation. |
| Dual-output interface (LVDS or CMOS) | Reduces system-level EMI (LVDS) or simplifies interface to legacy CMOS logic, selected per board revision. |
| Out-of-range (OR) detection outputs | Provides immediate hardware-level alert for signal saturation, enabling adaptive gain control or fault logging. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9445BCPZ-105 | 16-bit, 105 MSPS; 76 dBFS SNR @ 30 MHz; 64-lead LFCSP; single 3.3 V supply only. | Lacks 5 V AVDD2 rail and internal 1.6 V reference; lower SNR limits use in ultra-low-noise MRI front-ends. | Choose AD9445BCPZ-105 for space-constrained designs where 3.3 V-only supply and smaller footprint outweigh SNR trade-off. |
| ADS5463IPFP | 16-bit, 500 MSPS; 73.5 dBFS SNR @ 30 MHz; 80-lead HTQFP; requires external reference and driver. | Higher speed but lower SNR and no integrated T/H or reference; demands more support circuitry and layout effort. | Choose ADS5463IPFP only when >100 MSPS sampling is mandatory and system-level SNR budget permits external component overhead. |
Compared with AD9446BSVZ-100, AD9445BCPZ-105 offers higher sample rate in a smaller package but sacrifices 3.7 dB SNR and eliminates flexible analog supply architecture; ADS5463IPFP delivers raw speed but increases BOM count, power, and layout sensitivity-making AD9446BSVZ-100 optimal for balanced performance, integration, and ease of use in demanding IF sampling roles.

FAQ
What is the guaranteed maximum sampling rate for AD9446BSVZ-100?
The AD9446BSVZ-100 is guaranteed to operate at 100 MSPS across its full industrial temperature range (−40°C to +85°C), as confirmed in Table 4 of the datasheet. This rate is validated with LVDS outputs, internal 1.6 V reference, and DCS enabled. Lower rates (down to 1 MSPS) are supported, but 100 MSPS is the upper limit for full AC/DC specification compliance. AD9446BSVZ-100 maintains 79.7 dBFS SNR and 89 dBc SFDR at this rate with 30 MHz input.
Does AD9446BSVZ-100 require an external reference voltage?
No, AD9446BSVZ-100 includes an internal trimmed 1.6 V reference that sets a 3.2 Vp-p differential input range when the SENSE pin is tied to AGND. An external reference can be used by connecting SENSE to AVDD1, but it is not required. The VREF pin serves as I/O for reference configuration and must be decoupled with 0.1 μF and 10 μF capacitors to AGND regardless of reference mode. AD9446BSVZ-100 operates fully functional with only the internal reference.
How does the clock duty cycle stabilizer (DCS) function in AD9446BSVZ-100?
The DCS in AD9446BSVZ-100 actively corrects input clock duty cycle deviations using an internal feedback loop, ensuring consistent aperture timing and minimizing jitter-induced SNR degradation. When DCS MODE is pulled low (AGND), the circuit adapts to clock pulse widths as narrow as 4.0 ns high/low (per Table 4), maintaining full 100 MSPS performance even with non-50% duty cycles. AD9446BSVZ-100 datasheet specifies DCS is recommended for all high-accuracy applications.
What are the power supply requirements for AD9446BSVZ-100?
AD9446BSVZ-100 requires three independent supplies: AVDD1 = 3.3 V ±5% (314–346 mV tolerance), AVDD2 = 5.0 V ±5% (4.75–5.25 V), and DRVDD = 3.3 V ±5% for digital outputs. Total power consumption is 2.6–2.8 W in LVDS mode at 100 MSPS. AGND and DRGND must be kept separate except at the exposed heat sink, which is bonded to AGND. AD9446BSVZ-100 draws 401 mA from AVDD1 and 255 mA from AVDD2 under full load.
Can AD9446BSVZ-100 interface directly with an FPGA using LVDS outputs?
Yes, AD9446BSVZ-100 provides ANSI-644-compliant LVDS outputs (D0± to D15±, DCO±, OR±) with 247–545 mV differential voltage and 1.125–1.375 V common-mode offset, matching standard FPGA LVDS input receivers. The DCO± clock is source-synchronous and aligned to data edges, enabling reliable capture without external delay tuning. AD9446BSVZ-100 requires 100 Ω termination at the FPGA side and proper PCB length matching for all bit/clock pairs.
