AD9760ARZ

Digital To Analog Converters Overview

The AD9760ARZ is a 10-bit, 125 MSPS CMOS digital-to-analog converter (DAC) from Analog Devices' TxDAC family. It features differential current outputs ranging from 2 mA to 20 mA and operates on a single supply of 2.7 V to 5.5 V. Key specifications include an integral nonlinearity (INL) of ±0.5 LSB and differential nonlinearity (DNL) of ±0.25 LSB. The device achieves a spurious-free dynamic range (SFDR) of 52 dBc at a 40 MHz output with a 125 MSPS clock rate. Power dissipation is 175 mW at 5 V with full-scale current, reducible to 45 mW at 3 V. It includes an on-chip 1.20 V reference and edge-triggered latches for parallel data input.

Digital To Analog Converters Feature Summary

• 125 MSPS update rate with 10-bit resolution in a 28-lead SOIC package
• Differential current outputs (IOUTA/IOUTB) adjustable from 2 mA to 20 mA via external resistor
• On-chip 1.20 V temperature-compensated bandgap voltage reference
• Edge-triggered input latches compatible with +3 V and +5 V CMOS logic families

Digital To Analog Converters Applications

• Communication transmit channels including basestations
• Set top boxes and digital radio links
• Direct Digital Synthesis (DDS) systems
• General instrumentation requiring high-speed DAC conversion

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'RZ' indicates RoHS compliance and lead-free termination when sourcing replacements. Confirm the package type is the standard 28-lead SOIC (300 mil width). Ensure the operating environment supports the specified industrial temperature range of -40°C to +85°C. Check for availability of the evaluation board AD9760-EBZ for design validation.

Digital To Analog Converters Selection Notes

Select the AD9760ARZ for applications requiring pin-compatible upgrades within the TxDAC family, which offers 8-, 12-, and 14-bit variants. Consider the AD9760-50 variant if operation is strictly limited to 50 MSPS. Evaluate power requirements carefully; reducing full-scale current significantly lowers dissipation but impacts output swing. Ensure the load impedance matches the 1.25 V output compliance range to maintain linearity.

Digital To Analog Converters Part Context

The AD9760ARZ belongs to the TxDAC product family, designed for optimized transmit signal paths in communication systems. It shares identical interface options, small outline packages, and pinouts with other members of the series, facilitating upward or downward component selection based on resolution and cost constraints without redesigning the PCB layout.

Digital To Analog Converters Replacement Considerations

The AD9760ARZRL is a reel-pack equivalent with identical electrical characteristics. The AD9760ARU is the TSSOP package variant. For lower speed requirements, the AD9760-50 is guaranteed for 50 MSPS operation.
