Overview
The AD9066JR is a dual 6-bit, 60 MSPS monolithic analog-to-digital converter (ADC) optimized for low-cost in-phase and quadrature demodulators. It operates from a single +5 V supply with 400 mW power dissipation. The device features an internal voltage reference, CMOS-compatible I/O, and a TTL-compatible ENCODE input. Key electrical parameters include a full-scale input range of 500 mV, 100 MHz input bandwidth, and 5.7 effective number of bits at 25°C. It is housed in a 28-lead SOIC package and rated for the 0°C to 70°C commercial temperature range.
Feature Summary
- Dual matched ADCs integrated on a single chip
- Internal voltage reference for self-biasing AC-coupled inputs
- CMOS-compatible digital outputs with TTL-compatible clock threshold
- Low-power operation using a single +5 V supply
Applications
- Direct broadcast satellite receivers
- QAM demodulators
- Wireless LAN systems
- VSAT receivers
Procurement Notes
Verify the specific ordering suffix to confirm the package type and temperature grade. The JR suffix indicates a 28-lead SOIC package suitable for the commercial temperature range. Ensure compatibility with system requirements regarding interface standards and thermal management before finalizing procurement decisions.
Selection Notes
Select this component when designing cost-effective I/Q demodulation circuits requiring moderate resolution and high sampling rates. Consider the 6-bit resolution and 60 MSPS speed against application needs. Evaluate the internal reference capabilities for simplified biasing designs compared to external reference solutions.
Part Context
The AD9066 series includes variants for different temperature ranges and packages. The AD9066AR and ARS support industrial temperatures (-40°C to +85°C), while the JR is limited to commercial grades (0°C to 70°C). All variants share identical functional specifications and pinouts.
Replacement Considerations
No direct public substitutes are documented. Review the AD9059 or AD9051 if higher bit resolution is required, though these differ significantly in architecture and performance metrics.
FAQ
How does the AD9066 handle AC-coupled inputs?
The device is internally biased to midscale via its internal voltage reference, allowing it to accept AC-coupled signals without external DC biasing circuitry.
What is the logic level compatibility of the encode clock?
The ENCODE input utilizes a CMOS input stage with a TTL-compatible threshold of 1.4 V, ensuring compatibility with standard logic families.
What packaging options are available for the AD9066JR?
The AD9066JR is exclusively available in a 28-lead Small Outline Integrated Circuit (SOIC) package.
