AD5314ARMZ

The AD5314ARMZ is a quad 10-bit buffered voltage output DAC from Analog Devices. It integrates four complete DACs with on-chip output buffers in a compact 10-MSOP package. The device uses a string DAC architecture ensuring monotonic performance. It operates from a 2.5V to 5.5V supply and typically consumes 500 µA at 3V and 600 µA at 5V, making it suitable for battery-powered applications. The output voltage range is from 0V to V_REF, and the external reference sets the full-scale output. The digital interface supports SPI and DSP-compatible 3-wire serial protocol with double-buffered input logic, allowing simultaneous update of all outputs via the LDAC function. Settling time is 9 µs typical, and the slew rate is 0.7 V/µs. The device includes a power-down mode that reduces current to 80 nA at 3V and 200 nA at 5V. The operating temperature range is -40°C to +105°C, suitable for industrial and automotive environments. The package is a 10-lead MSOP (0.118", 3.00mm Width). Power dissipation is typically 1.5 mW at 3V and 3 mW at 5V. INL and DNL are ±0.5 LSB and ±0.05 LSB respectively.
