AD5300BRTZ-500RL7

Digital To Analog Converters Overview

The AD5300BRTZ-500RL7 is a single-channel, 8-bit buffered voltage output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates from a single 2.7 V to 5.5 V supply and consumes 140 μA at 5 V. The device features an on-chip precision output amplifier capable of rail-to-rail output swing with a slew rate of 1 V/μs. Its reference is derived directly from the power supply inputs, maximizing dynamic output range. Key electrical parameters include a settling time of 6 μs, differential nonlinearity of ±0.25 LSB, and integral nonlinearity of ±1 LSB. The component supports a high-speed 3-wire serial interface with clock rates up to 30 MHz and includes three software-selectable power-down modes.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging configuration required for the assembly line. Confirm that the B version temperature rating (-40°C to +105°C) meets the operational environment specifications. Ensure the SOT-23-6 package footprint matches the PCB design constraints. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, low-cost 8-bit DAC is required for battery-operated systems. The internal reference derived from VDD simplifies design by eliminating external reference components. Choose this part over higher-resolution variants if system accuracy requirements are within ±1 LSB. Consider the 3-wire interface compatibility with the host microcontroller's available pins and clock speeds before finalizing the selection.

Digital To Analog Converters Part Context

The AD5300 belongs to a family of pin-compatible DACs that includes the 10-bit AD5310 and the 12-bit AD5320. All members of this family share the same 6-lead SOT-23 and 8-lead MSOP package options, facilitating design upgrades without altering the physical board layout. This specific model represents the entry-level resolution option within the series, optimized for cost-sensitive applications requiring moderate precision.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same family include the AD5310 (10-bit) and AD5320 (12-bit). These alternatives offer higher resolution while maintaining identical package dimensions and interface protocols. Verify that the increased resolution aligns with the system's noise floor and accuracy requirements before substituting.
