AD5327BRUZ

The AD5327BRUZ is a quad 12-bit buffered voltage-output Digital-to-Analog Converter (DAC) manufactured by Analog Devices Inc. This component is designed for operation from a single 2.5 V to 5.5 V power supply, consuming a low quiescent current of 400 μA at 3 V and 500 μA at 5 V. It features a 12-bit resolution and supports a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, operating at clock rates up to 30 MHz.

The DAC includes on-chip rail-to-rail output buffer amplifiers, allowing the outputs to swing rail-to-rail. It also incorporates features such as power-on reset to 0 V, an asynchronous clear facility, and simultaneous output updates via the LDAC pin. The device offers a power-down mode that reduces current consumption to as low as 90 nA at 3 V.

Packaged in a 16-lead TSSOP, the AD5327BRUZ is suitable for surface mount applications. Its operating temperature range is from -40°C to +105°C, making it a versatile choice for various industrial and portable applications.

Key applications include portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, programmable attenuators, and industrial process control.
