AD9762ARRL

Digital To Analog Converters Overview

The AD9762ARRL is a 12-bit, 1-channel digital-to-analog converter (DAC) from Analog Devices Inc., operating at update rates up to 125 MSPS. It features a segmented current source architecture with an internal 1.2 V temperature-compensated bandgap reference and edge-triggered input latches. The device supports single-supply operation between 2.7 V and 5.5 V, delivering a nominal full-scale output current of 20 mA with high output impedance (>100 kΩ). Key electrical parameters include a settling time of 35 ns, integral nonlinearity of ±1 LSB, and power consumption as low as 45 mW at reduced current or ~25 mW in power-down mode.

Digital To Analog Converters Feature Summary

• 12-bit resolution with 125 MSPS update rate
• Integrated 1.2 V temperature-compensated bandgap reference
• Single supply voltage range of 2.7 V to 5.5 V
• Nominal 20 mA full-scale current output

Digital To Analog Converters Applications

• Communication system transmit signal paths
• Portable battery-powered devices
• Low-power wireless local loop systems

Digital To Analog Converters Procurement Notes

Verify the package type matches the required footprint, as the suffix 'RL' typically indicates tape-and-reel packaging while other variants may use tubes. Confirm that the specific revision level meets the design requirements for interface timing and power management features.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution and 125 MSPS speed are required within a single-supply CMOS environment. Consider the TxDAC family's pin compatibility if future upgrades to 8-bit, 10-bit, or 14-bit resolutions are anticipated without PCB redesign.

Digital To Analog Converters Part Context

The AD9762 is part of the TxDAC series, which includes pin-compatible 8-bit, 10-bit, and 14-bit DACs. This family shares identical interface options, small outline packages, and pin arrangements, allowing designers to scale performance and cost across different product tiers using the same board layout.

Digital To Analog Converters Replacement Considerations

Other members of the TxDAC family, such as the AD9760 (10-bit) or AD9764 (14-bit), offer pin-compatible alternatives for adjusting resolution and cost. Verify that the specific interface logic levels and power requirements remain compatible with the existing system design.
