AD5300BRT-REEL7

Digital To Analog Converters Overview

The AD5300BRT-REEL7 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. It utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 30 MHz. The reference voltage is derived directly from the power supply inputs. Key specifications include ±1 LSB relative accuracy, ±0.25 LSB differential nonlinearity, and a settling time of 6 μs. The component is housed in a 6-lead SOT-23 package.

Digital To Analog Converters Feature Summary

• 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP
• Power supply derived reference for maximum dynamic range
• Power-on reset ensures DAC output initializes to 0 V

Digital To Analog Converters Applications

• Portable battery-powered instruments
• Digital gain and offset adjustment circuits
• Programmable voltage and current sources
• Programmable attenuators

Digital To Analog Converters Procurement Notes

Verify that the ordering suffix REEL7 corresponds to tape-and-reel packaging containing 3000 units, as indicated by standard manufacturer conventions for this suffix. Confirm the B version temperature range (-40°C to +105°C) matches the application requirements. Ensure the SOT-23 package footprint aligns with the PCB design. Cross-reference the specific part number with official Analog Devices documentation to confirm availability and exact reel specifications.

Digital To Analog Converters Selection Notes

Select the AD5300BRT-REEL7 when a single-channel, low-cost, 8-bit DAC is required for battery-operated systems. The choice between SOT-23 and MSOP packages depends on board space constraints; this model uses SOT-23. Consider the external reference requirement if higher accuracy than the supply-derived reference allows. Verify that the 3-wire interface timing meets the microcontroller or DSP clock speed limitations, noting the max frequency is 30 MHz at VDD ≥ 3.6 V.

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 variants share the same 6-lead SOT-23 and 8-lead MSOP package options and similar electrical characteristics, differing primarily in resolution. This family is designed for micropower applications requiring minimal component count and low supply current.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same family include the AD5310 (10-bit) and AD5320 (12-bit). Other single-channel 8-bit DACs may require schematic modifications due to differences in interface protocols, pinouts, or power requirements.
