AD5305BRMZ-REEL7

Digital To Analog Converters Overview

The AD5305BRMZ-REEL7 is a quad 8-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.5 V to 5.5 V supply, consuming 500 μA at 3 V and 600 μA at 5 V. The device features four rail-to-rail output amplifiers with a slew rate of 0.7 V/μs and a settling time of 6 μs. It utilizes a 2-wire I²C-compatible serial interface supporting clock rates up to 400 kHz. Key specifications include ±0.15 LSB typical INL, ±0.02 LSB typical DNL, and power-down current as low as 80 nA at 3 V.

Digital To Analog Converters Feature Summary

• Quad 8-bit resolution with rail-to-rail buffered voltage outputs
• Low power consumption: 500 μA normal mode, 80 nA power-down at 3 V
• 2-wire I²C/SMBus compatible serial interface with 400 kHz max clock
• Power-on reset ensures outputs initialize to 0 V

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 B version designation for ±0.625 LSB INL accuracy. Confirm the MSOP-10 package and REEL7 tape-and-reel packaging format. Ensure compatibility with the required 2.5 V to 5.5 V supply range and external reference voltage configuration.

Digital To Analog Converters Selection Notes

Select this component for applications requiring four independent analog outputs with high precision in a compact footprint. The B version offers tighter linearity than the A version. Consider the 80 nA power-down mode for battery-operated devices where standby current must be minimized.

Digital To Analog Converters Part Context

This part belongs to the AD5305/AD5315/AD5325 family of quad DACs. The AD5305 specifically provides 8-bit resolution, while the AD5315 and AD5325 offer 10-bit and 12-bit resolutions respectively. All share the same pinout and interface logic but differ in accuracy and code ranges.

Digital To Analog Converters Replacement Considerations

The AD5315BRMZ-REEL7 and AD5325BRMZ-REEL7 are pin-compatible upgrades offering higher resolution. For lower cost applications, the A-version parts (AD5305ARMZ-REEL7) provide wider linearity tolerances.
