The AD7809BST from Analog Devices is an octal (8-channel) 10-bit digital-to-analog converter (DAC) designed for parallel data loading. This component operates from a wide supply voltage range of +3.3 V to +5 V (–10%) and integrates an on-chip voltage reference, simplifying system design.
Key features include double-buffered data inputs, allowing for simultaneous updates of all analog outputs via the asynchronous LDAC input. The device incorporates on-chip control registers for both system-wide and individual channel management, including standby and clear functions. The AD7809BST provides output signals in the form of VBIAS – VSWING, with VSWING derived internally from VBIAS. An on-chip Sub DAC allows for shifting the transfer function of individual DAC channels.
This DAC is supplied in a 44-TQFP (10x10 mm) surface-mount package, making it suitable for various electronic applications requiring precise digital-to-analog conversion. Its design facilitates efficient integration into systems needing multiple analog output channels controlled digitally.
The AD7809BST operates from a 3.3V to 5V supply.
The AD7809BST is available in a 44-TQFP surface-mount package.
The AD7809BST is marked as RoHS3 Compliant, though this status is not verified.
The AD7809BST features 8 independent DAC channels.
The AD7809BST has a resolution of 10 bits.
The AD7809BST includes a 1.23V internal reference.
