AD5327BRU

Digital To Analog Converters Overview

The AD5327BRUZ is a quad, 12-bit buffered voltage-output digital-to-analog converter (DAC) housed in a 16-lead TSSOP package. It operates from a single 2.5 V to 5.5 V supply and consumes 400 μA at 3 V. The device features on-chip rail-to-rail output amplifiers with a slew rate of 0.7 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. Key specifications include ±10 LSB INL for the B version, a maximum settling time of 10 μs, and power-down current as low as 90 nA at 3 V.

Digital To Analog Converters Feature Summary

• Quad 12-bit resolution with ±10 LSB integral nonlinearity (B version)
• Rail-to-rail output swing with 0.7 V/μs slew rate
• Low power consumption: 400 μA active, 90 nA power-down
• 3-wire serial interface supporting daisy-chaining via SDO

Digital To Analog Converters Applications

• Portable battery-powered instruments
• Digital gain and offset adjustment circuits
• Programmable voltage and current sources
• Industrial process control systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type (tube vs. reel) and temperature grade. Ensure the design accounts for the external reference configuration requirements specified in the datasheet. Confirm pinout compatibility if substituting within the AD5307/AD5317 family.

Digital To Analog Converters Selection Notes

Select the AD5327BRUZ when four independent 12-bit channels are required in a compact footprint. The B version offers tighter linearity specifications (±10 LSB INL) compared to the A version. Consider the external reference input range (0.25 VDD to VDD unbuffered, 1 VDD to VDD buffered) when designing the reference circuitry. Ensure the load capacitance does not exceed 200 pF for stable operation.

Digital To Analog Converters Part Context

The AD5327 is part of the AD5307/AD5317/AD5327 family, which shares an identical pinout to allow for resolution upgrades without PCB redesign. While the AD5307 provides 8-bit resolution and the AD5317 provides 10-bit, the AD5327 delivers 12-bit precision. All variants feature the same low-power architecture and serial interface capabilities.

Digital To Analog Converters Replacement Considerations

The AD5327ARUZ serves as a lower-cost alternative with ±16 LSB INL. For higher channel counts, the AD5328 offers an octal configuration. The AD5317BRUZ and AD5307BRUZ are pin-compatible options if lower resolution is acceptable.
