Product details
Overview
AD9066AR-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, an on-chip voltage reference, and CMOS-compatible digital outputs. It operates from a single +5 V supply, delivers 400 mW typical power dissipation, and supports ac-coupled inputs with 500 mV full-scale range - enabling direct digitization of recovered QPSK signal components in DBS systems.
For engineers reviewing the AD9066AR-REEL datasheet, AD9066AR-REEL pinout, AD9066AR-REEL application, or AD9066AR-REEL equivalent, key selection considerations include its industrial temperature range (–40°C to +85°C), SOIC-28 package, internal reference architecture, crosstalk rejection of 40–50 dBc, and guaranteed monotonicity across both channels.
Technical Context
The AD9066AR-REEL employs a patented interpolated flash architecture using 32 comparator preamplifiers to generate 64 quantization levels, minimizing input capacitance (10–15 pF) and enabling high-speed sampling. Its dual-channel design features independent analog inputs (INA, INB) and dedicated reference nodes (REF A, REF B, VT, VB) for precise midscale biasing in both ac- and dc-coupled configurations.
Each channel provides offset binary coding, latched CMOS outputs with 11–12 ns propagation delay, and TTL-compatible ENCODE input (1.4 V threshold). Aperture uncertainty is 10 ps rms, supporting accurate sampling of 15.5 MHz analog signals with 5.2–5.7 effective bits at 60 MSPS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 6-bit per channel - defines 64 discrete output codes for each I/Q path. |
| Max Conversion Rate | 60 MSPS - enables real-time digitization of broadband QPSK signals up to 15.5 MHz input frequency. |
| Full-Scale Input Range | 450–530 mV - sets usable analog swing for ac-coupled I/Q inputs without external scaling. |
| Effective Number of Bits | 5.2–5.7 bits @ +25°C - reflects actual dynamic resolution after noise and distortion. |
| Crosstalk Rejection | 40–50 dBc - ensures minimal interference between Channel A and Channel B during simultaneous sampling. |
| Power Dissipation | 400–600 mW - supports low-power system design in space-constrained DBS receiver modules. |
| Supply Voltage | +4.75 V to +5.25 V - allows operation from standard 5 V rails with ±5% tolerance. |
Pinout & Package
AD9066AR-REEL is housed in a 28-lead SOIC (R-28) package with gull-wing leads, 0.050" pitch, and JEDEC MS-012AC dimensions (0.7125" × 0.2992"). The package supports surface-mount reflow and provides thermal resistance θJA = 45°C/W.
| 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. |
| INA (Pin 6), INB (Pin 11) | Analog input channels | Dedicated differential-capable inputs for in-phase and quadrature signal paths; internally biased to midscale. |
| REF A (Pin 10), REF B (Pin 12) | Channel-specific reference taps | Provide mid-reference voltage for each ADC; used for external offset compensation in dc-coupled designs. |
| VT (Pin 9), VB (Pin 13) | Reference ladder terminals | Define top and bottom of internal 620 Ω resistor ladder; enable full-scale range adjustment via external voltage forcing. |
| D0A–D5A (Pins 23,24,25,26,27,28), D0B–D5B (Pins 15–20) | Digital outputs | CMOS-compatible, offset binary-coded 6-bit words per channel; LSB-aligned, no inversion required. |
| +VS (Pins 2,5,8,21) | Power supply | Single +5 V rail powers analog core, digital logic, and output drivers; multiple pins reduce IR drop. |
| GND (Pins 3,4,7,14,15,22) | Ground return | Multiple ground pins ensure low-impedance return paths for analog and digital sections; must connect to common ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dual matched ADCs on single die | Guarantees <16 mV gain mismatch between channels - critical for vector accuracy in QPSK demodulation. |
| On-chip voltage reference | Eliminates need for external reference ICs; provides stable midscale bias for ac-coupled inputs without external components. |
| Self-biased for ac-coupled inputs | Internally sets analog input midpoint at +VS – 1.1 V - enables direct coupling via blocking capacitor with no external bias network. |
| Low-power 400 mW operation | Reduces thermal load in densely packed satellite receiver front-ends and simplifies heatsinking requirements. |
| Industrial temperature range | Rated for –40°C to +85°C - suitable for outdoor DBS installations and uncontrolled environmental enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9065AR-REEL | Single-channel 6-bit, 60 MSPS ADC in same SOIC-28 package; lacks second channel and REF B/VB pins. | Suitable only for non-I/Q or time-interleaved architectures; cannot replace dual-path functionality. | Select only when system uses time-multiplexed sampling or separate ADCs per path. |
| ADS830U | 8-bit, 60 MSPS single-channel ADC from Texas Instruments; no integrated reference; requires external biasing and dual supplies. | Higher resolution but higher power (650 mW); no native I/Q matching or crosstalk control. | Choose when ENOB >5.7 is mandatory and board area allows discrete reference and layout isolation. |
Compared with AD9066AR-REEL, AD9065AR-REEL reduces channel count and integration, while ADS830U trades off matching precision and reference integration for raw resolution - making AD9066AR-REEL uniquely suited for cost-sensitive, space-constrained I/Q demodulation where channel correlation matters.

FAQ
What is the operating temperature range for AD9066AR-REEL?
The AD9066AR-REEL is rated for industrial operation from –40°C to +85°C. This specification is confirmed in the Ordering Guide and Electrical Characteristics tables, where parameters like full-scale input range and ENOB are guaranteed across this full range. The "AR" suffix explicitly denotes the industrial grade, distinguishing it from the commercial-grade AD9066JR (0°C to +70°C).
Does AD9066AR-REEL require an external voltage reference?
No, AD9066AR-REEL does not require an external voltage reference. It integrates an on-chip resistor ladder with VT and VB terminals, providing a stable midscale bias point. For ac-coupled inputs, this internal reference self-biases the analog input to +VS – 1.1 V; for dc-coupled use, REF A and REF B can be driven externally to compensate for supply or temperature drift.
What package type is used for AD9066AR-REEL?
AD9066AR-REEL is supplied in a 28-lead Small Outline Integrated Circuit (SOIC) package, designated R-28 by Analog Devices. Mechanical drawings confirm JEDEC MS-012AC outline dimensions (0.7125" × 0.2992"), gull-wing leads, and 0.050" pitch - distinct from the SSOP (RS-28) variant used in AD9066ARS.
How is crosstalk performance specified for AD9066AR-REEL?
AD9066AR-REEL specifies crosstalk rejection as 40–50 dBc in the Electrical Characteristics table, measured at +25°C. This parameter quantifies leakage from one analog channel (e.g., INB) into the other (e.g., INA) during simultaneous sampling - a critical spec for maintaining I/Q orthogonality in QPSK demodulation.
What digital output format does AD9066AR-REEL use?
AD9066AR-REEL outputs data in offset binary format, as explicitly stated in the Electrical Characteristics table under "Digital Outputs." In this coding scheme, the midscale code (000000) corresponds to the analog input's midpoint voltage (+VS – 1.1 V), with positive full scale encoded as 111111 and negative full scale as 000001 - eliminating sign extension complexity in downstream logic.
