Overview
The AD9066ARS is a dual 6-bit, 60 MSPS monolithic analog-to-digital converter (ADC) designed for low-cost I and Q demodulators. It operates from a single +5 V supply with 400 mW power dissipation. The device features CMOS-compatible digital outputs and an internal voltage reference. It supports offset binary coding with a full-scale input range of 500 mV ± 5%. The ARS variant provides an industrial temperature rating of –40°C to +85°C in a 28-lead SSOP package.
Feature Summary
- Dual matched ADCs integrated on a single chip
- CMOS-compatible I/O with TTL-compatible encode clock threshold
- Internal voltage reference for self-biasing AC-coupled inputs
- Single +5 V supply operation with low power dissipation
Applications
- Direct Broadcast Satellite (DBS) Receivers
- QAM Demodulators
- Wireless LANs
- VSAT Receivers
Procurement Notes
Verify the specific ordering suffix to confirm the package type and temperature grade. The ARS designation indicates the industrial temperature range and SSOP package. Confirm pinout compatibility if replacing older variants. Ensure proper ESD handling during assembly due to sensitivity. Check datasheet revision for any updates to electrical characteristics or mechanical dimensions before finalizing procurement.
Selection Notes
Select this component for applications requiring dual-channel digitization at moderate speeds. The internal reference simplifies biasing for AC-coupled signals. Consider thermal management for the SSOP package as junction-to-ambient resistance is higher than SOIC versions. Verify that the 6-bit resolution meets system dynamic performance requirements. Ensure the encode clock duty cycle meets specifications for optimal performance above 40 MSPS.
Part Context
The AD9066 series includes the JR (commercial), AR (industrial SOIC), and ARS (industrial SSOP) variants. All share identical electrical characteristics but differ in packaging and operating temperature ranges. The ARS specifically utilizes the RS-28 SSOP form factor. This family targets cost-sensitive quadrature demodulation applications where dual-channel synchronization is required.
Replacement Considerations
The AD9066JR offers the same electrical performance in a commercial temperature range with an SOIC package. The AD9066AR provides industrial temperature ratings but uses the SOIC package instead of SSOP. Both are direct functional replacements if package footprint allows.
