AD9760AR

Digital To Analog Converters Overview

The AD9760AR is a 10-bit, 125 MSPS digital-to-analog converter from the TxDAC family. It features differential current outputs with a nominal full-scale range of 2 mA to 20 mA and an output impedance exceeding 100 kΩ. The device operates on a single supply voltage between 2.7 V and 5.5 V, dissipating 175 mW at 5 V with maximum current. Key specifications include a settling time of 35 ns, an on-chip 1.20 V reference, and edge-triggered input latches compatible with CMOS logic families.

Digital To Analog Converters Feature Summary

• 125 MSPS update rate with 10-bit resolution
• Differential current outputs adjustable from 2 mA to 20 mA
• On-chip 1.20 V bandgap reference
• Single +3 V or +5 V supply operation

Digital To Analog Converters Applications

• Communication transmit channels for basestations
• Set top boxes
• Digital radio link systems
• Direct Digital Synthesis (DDS)
• Instrumentation

Digital To Analog Converters Procurement Notes

Verify the package type matches the specific suffix: 'AR' indicates a 28-lead SOIC package, while 'ARU' denotes a TSSOP package. Confirm the temperature range is industrial (-40°C to +85°C). Ensure the required revision level meets design specifications, as performance characteristics may vary between revisions.

Digital To Analog Converters Selection Notes

Select the AD9760AR when a 10-bit resolution and 125 MSPS speed are required in a 28-lead SOIC package. Consider the AD9760ARU if a TSSOP footprint is preferred. For lower speed requirements, the AD9760-50 variant supports up to 60 MSPS. Ensure the application can accommodate the differential current output topology or includes necessary termination resistors.

Digital To Analog Converters Part Context

The AD9760 is part of the TxDAC product family, which offers pin-compatible options ranging from 8-bit to 14-bit resolutions. This allows for flexible component selection based on performance and cost without changing the board layout. The AD9760 specifically targets high-performance transmit signal paths within communication systems.

Digital To Analog Converters Replacement Considerations

The AD9760-50 is a pin-compatible alternative with a reduced maximum update rate of 60 MSPS. Other members of the TxDAC family, such as the AD9750 or AD9761, share similar interfaces but differ in channel count or resolution.
