AD5323ARUZ

Digital To Analog Converters Overview

The AD5323ARUZ is a dual 12-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices, housed in a 16-lead TSSOP package. It operates on a single 2.5 V to 5.5 V supply with typical current consumption of 230 μA at 3 V and 300 μA at 5 V. The device features rail-to-rail output amplifiers with a slew rate of 0.7 V/μs and supports serial interfaces including SPI, QSPI, Microwire, and DSP standards via a 3-wire interface clocking up to 30 MHz. Key specifications include ±1 LSB maximum differential nonlinearity (DNL), ±16 LSB maximum integral nonlinearity (INL), and power-down currents as low as 50 nA at 3 V.

Digital To Analog Converters Feature Summary

• Dual 12-bit resolution with guaranteed monotonicity by design
• Rail-to-rail output swing with on-chip buffer amplifiers
• Versatile 3-wire serial interface compatible with standard protocols
• Micropower operation: 230 μA active, down to 50 nA in power-down

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 the specific revision (Rev. B datasheet) and temperature grade (Industrial -40°C to +105°C) against project requirements. Confirm packaging details, as the 'RUZ' suffix indicates a tube package, while other suffixes may denote reel options. Ensure reference input configuration (buffered vs. unbuffered) matches the external reference source impedance capabilities.

Digital To Analog Converters Selection Notes

Select the AD5323ARUZ when 12-bit resolution and dual-channel output are required within a compact 16-lead TSSOP footprint. Consider the A-version linearity specs (±16 LSB INL) for cost-sensitive applications where higher precision variants like the AD5323BRUZ (±8 LSB INL) are not necessary. Evaluate power constraints, as the device draws minimal current in power-down mode, making it suitable for battery-operated systems.

Digital To Analog Converters Part Context

The AD5323ARUZ belongs to the AD5303/AD5313/AD5323 family of dual DACs. It shares the same pinout, interface, and general architecture as the 8-bit AD5303 and 10-bit AD5313, differing primarily in resolution and associated linearity specifications. This family is designed for low-power, space-constrained analog control applications.

Digital To Analog Converters Replacement Considerations

The AD5323BRUZ offers improved linearity (±8 LSB INL vs. ±16 LSB INL) with identical pinout and functionality. For lower resolution needs, the AD5313ARUZ (10-bit) or AD5303ARUZ (8-bit) are pin-compatible alternatives.
