Product details
Overview
AD9066ARS-REEL from Analog Devices is a dual 6-bit, 60 MSPS monolithic analog-to-digital converter optimized for I/Q demodulation in satellite receivers. It integrates two matched ADCs, on-chip voltage reference, and CMOS-compatible digital outputs operating from a single +5 V supply. Key confirmed specs include 500 mV full-scale input range, ±1.0 LSB integral linearity, 10 ps rms aperture jitter, and –40°C to +85°C industrial temperature rating.
For engineers reviewing the AD9066ARS-REEL datasheet, AD9066ARS-REEL pinout, AD9066ARS-REEL application, or AD9066ARS-REEL equivalent, this page delivers verified technical context, package mapping, real-world use scenarios in DBS and QAM systems, and validated alternative parts with documented functional and application differences.
Technical Context
The AD9066ARS-REEL implements a patented interpolated flash architecture using 32 comparator preamplifiers to achieve 64 quantization levels, minimizing input capacitance (10–15 pF) and enabling high-speed sampling at 60 MSPS. Its internal resistor ladder reference (VT–VB) establishes a nominal 500 mV full-scale range, with midscale biasing self-adjusted for AC-coupled inputs.
Dual-channel operation supports simultaneous digitization of in-phase (INA) and quadrature (INB) signals, with independent REF A/REF B pins allowing external offset control in DC-coupled configurations. Digital outputs are latched with three pipeline stages, featuring 11–12 ns output delay (tPD) and TTL-compatible ENCODE input (1.4 V threshold).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 6-bit dual-channel ADC - delivers two parallel 6-bit words per sample for I/Q vector digitization. |
| Max Conversion Rate | 60 MSPS - supports symbol rates up to 10 Mbaud in QPSK satellite demodulators without undersampling. |
| Full-Scale Input Range | 450–530 mV - defined by internal 620 Ω resistor ladder; enables direct interfacing with IF stages in DBS receivers. |
| Integral Linearity Error | ±1.0 LSB - ensures accurate amplitude representation across full dynamic range for coherent demodulation. |
| Aperture Uncertainty | 10 ps rms - limits SNR degradation to ≤36 dB SINAD at 15.5 MHz input, critical for phase-sensitive QAM. |
| Supply Voltage | +4.75 V to +5.25 V - single-supply operation simplifies power design and reduces board-level regulation complexity. |
| Power Dissipation | 400–600 mW - low-power profile suitable for thermally constrained satellite receiver front-ends. |
Pinout & Package
AD9066ARS-REEL is housed in a 28-lead SSOP (RS-28) package with 0.65 mm pitch, 10.34 mm × 7.90 mm body size, and exposed thermal pad not connected internally. Pin assignments are validated per Analog Devices' official pin descriptions and top-view mechanical drawing for RS-28 variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ENCODE (Pin 1) | Sampling clock input | TTL-compatible CMOS input (1.4 V threshold); rising-edge triggered; requires ≥7 ns pulse width for stable 60 MSPS operation. |
| INA (Pin 6), INB (Pin 11) | Analog signal inputs | High-impedance (22–57 kΩ) differential-capable inputs biased to midscale; accept 3.7–4.2 V DC common-mode for bipolar drive. |
| REF A (Pin 10), REF B (Pin 12) | ADC reference midpoints | Provide feedback path for external offset compensation in DC-coupled designs; bypass to GND with 0.1 µF ceramic capacitor. |
| VT (Pin 9), VB (Pin 13) | Voltage reference taps | Top and bottom of internal 620 Ω ladder; allow full-scale range adjustment (e.g., 705 mV or 1.6 V) via external voltage forcing. |
| D0A–D5A (Pins 23–28), D0B–D5B (Pins 15–20) | Digital outputs | CMOS-compatible, offset binary coding; drive 1 mA loads with VOH ≥3.8 V / VOL ≤0.4 V; latched with pipeline delays. |
| +VS (Pins 2, 5, 8, 21) | Power supply | Single +5 V rail powers analog core, digital logic, and output drivers; requires local 0.1 µF ceramic bypass at each pin. |
| GND (Pins 3, 4, 7, 15, 22) | Ground reference | Multiple dedicated ground pins minimize noise coupling between analog and digital sections; must connect to single low-impedance plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dual matched ADCs on single die | Guarantees <16 mV gain matching between channels - essential for maintaining I/Q amplitude balance in demodulator front-ends. |
| On-chip voltage reference | Eliminates need for external reference IC; provides stable midscale bias for AC-coupled inputs without external components. |
| Self-biased for AC-coupled inputs | Internally sets analog input common-mode to +VS – 1.1 V - enables direct connection to transformer-coupled IF stages in DBS LNBs. |
| Low-power 400 mW dissipation | Reduces thermal load in compact satellite receiver modules; allows use in fanless set-top box enclosures. |
| CMOS-compatible I/O with TTL threshold | Interfaces directly with FPGA or DSP without level-shifting; 1.4 V ENCODE threshold ensures robust timing margin with standard logic families. |
Applications
| Direct Broadcast Satellite (DBS) Receivers | QAM Demodulators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9065ARS-REEL | Single 6-bit, 60 MSPS ADC in same RS-28 package; no dual-channel or REF A/B pins. | Suitable only for non-I/Q applications requiring one ADC channel; cannot replace AD9066ARS-REEL in quadrature systems. | Select when system uses separate I/Q paths or external multiplexing; verify layout accommodates missing REF/INB pins. |
| MAX1198ETL+ | Dual 6-bit, 40 MSPS ADC in 28-pin TQFN; lacks on-chip reference; requires external 1.25 V reference. | Lower max sample rate limits use in >10 Mbaud QPSK; higher input capacitance (20 pF) degrades high-frequency SNR. | Consider for cost-sensitive designs where 40 MSPS suffices and board space allows external reference routing. |
Compared with AD9066ARS-REEL, AD9065ARS-REEL omits critical I/Q functionality and reference flexibility, while MAX1198ETL+ trades speed and integration for smaller footprint-neither offers drop-in replacement capability, and both require PCB redesign and signal chain revalidation.

FAQ
What is the operating temperature range for AD9066ARS-REEL?
The AD9066ARS-REEL is rated for industrial operation from –40°C to +85°C, as confirmed in the Ordering Guide and Electrical Characteristics table. This range applies to all specified parameters including full-scale input range, linearity, and conversion rate. The "ARS" suffix explicitly denotes the industrial-grade version, distinct from the commercial-grade AD9066JR (0°C to +70°C). Thermal impedance data for the RS-28 package (θJA = 78.58°C/W) further validates its suitability for uncooled embedded environments.
Does AD9066ARS-REEL require an external voltage reference?
No, AD9066ARS-REEL does not require an external voltage reference. It integrates an on-chip resistor ladder with VT and VB terminals, generating a stable midscale bias point. REF A and REF B pins provide access to internal midpoint voltages for optional external feedback in DC-coupled applications, but are not mandatory. The device achieves self-biasing for AC-coupled inputs without any external reference components, reducing BOM count and layout complexity.
What is the full-scale input range specification for AD9066ARS-REEL?
The full-scale input range for AD9066ARS-REEL is 450 mV to 530 mV, as specified in the Electrical Characteristics table under "ANALOG INPUT" for the AD9066AR/ARS grade. This range is established by the internal 620 Ω resistor ladder and is nominally 500 mV ±5%. The range remains stable across the full industrial temperature range and is unaffected by supply voltage variations within +4.75 V to +5.25 V due to high PSRR (110–130 mV/V).
Can AD9066ARS-REEL be used with DC-coupled analog inputs?
Yes, AD9066ARS-REEL supports DC-coupled analog inputs. In such configurations, the REF A and REF B pins can be driven by external offset compensation circuits to maintain midscale tracking against temperature and supply drift. The datasheet confirms this capability in the "Using the AD9066" section, noting that REF pins feed back to internal comparators and may be used to correct DC offsets digitally or with op-amp networks like the AD712/AD812 example shown in Figure 6.
What package type is used for AD9066ARS-REEL?
AD9066ARS-REEL uses a 28-lead SSOP (Shrink Small Outline Package) with RS-28 designation, measuring 10.34 mm × 7.90 mm with 0.65 mm lead pitch. Mechanical drawings confirm it has gull-wing leads and no exposed thermal pad connection. This differs from the SOIC (R-28) package used by AD9066AR; the "RS" prefix in the part number explicitly identifies the SSOP variant, which offers higher pin density and improved thermal resistance (θJA = 78.58°C/W) compared to SOIC.
