AD7801BRUZ

AD7801BRUZ is an 8-bit digital-to-analog converter (DAC) from Analog Devices. It provides a buffered voltage output with rail-to-rail swing capability. The device features a parallel microprocessor-compatible interface with double-buffered logic, allowing easy connection to digital controllers. Key specifications include a settling time of 2 µs, integral nonlinearity (INL) of ±1 LSB, and differential nonlinearity (DNL) of ±1 LSB guaranteed monotonic. The DAC operates from a single supply voltage between 2.7V and5.5V, making it suitable for low-voltage systems. It uses an external reference for output scaling. The architecture is current source based with an on-chip output buffer. Power consumption is low, with typical supply current around 1.75 mA at 3.3V. The device includes a power-down function to further reduce power. The AD7801BRUZ is offered in a 20-lead TSSOP package (0.173", 4.40mm width) for surface mount assembly. It operates over an extended temperature range of -40°C to +105°C. This DAC is ideal for applications such as portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, and programmable attenuators.
