AD5307ARU

Digital To Analog Converters Overview

The AD5307ARU is a quad, 8-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 ±1 LSB INL for the A version, power-on reset to 0 V, and simultaneous output updates via the LDAC pin.

Digital To Analog Converters Feature Summary

• Quad 8-bit resolution with ±1 LSB INL (A version)
• Rail-to-rail buffered outputs with 0.7 V/μs slew rate
• Low power consumption: 400 μA @ 3 V, 90 nA power-down current
• 3-wire serial interface (SPI/QSPI/MICROWIRE/DSP) up to 30 MHz

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'R' against the official ordering guide to confirm package type and tape/reel configuration. Ensure the required accuracy version (A or B) matches the application needs, as INL specifications differ between versions. Confirm RoHS compliance status for the specific manufacturing lot.

Digital To Analog Converters Selection Notes

Select the AD5307 when four independent 8-bit channels are required in a compact footprint. Choose this part over higher-resolution variants if cost and lower power are priorities. Ensure the reference voltage range (0.25 VDD to VDD unbuffered, 1 V to VDD buffered) aligns with the system's reference source. Verify that the 3-wire interface timing meets the microcontroller's capabilities.

Digital To Analog Converters Part Context

The AD5307 is part of the nanoDAC family, sharing the same 16-lead TSSOP pinout with the AD5317 (10-bit) and AD5327 (12-bit). This common pinout allows designers to upgrade resolution without redesigning the PCB layout. The device is designed for industrial and consumer applications requiring multiple low-power DAC channels.

Digital To Analog Converters Replacement Considerations

The AD5317 and AD5327 are pin-compatible upgrades offering 10-bit and 12-bit resolution respectively. For direct replacement, ensure the higher resolution does not exceed the system's reference voltage swing requirements. No other cross-model substitutes are documented in the provided datasheet.
