Product Details

The AD5308/AD5318/AD5328 are octal 8-, 10-, and 12-bit buffered voltage output DACs in a 16-lead TSSOP. They operate from a single 2.5 V to 5.5 V supply, consuming 0.7 mA typical at 3 V. Their on-chip output amplifiers allow the outputs to swing rail-to-rail with a slew rate of 0.7 V/μs. The AD5308/ AD5318/AD5328 use a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards.

The references for the eight DACs are derived from two reference pins (one per DAC quad). These reference inputs can be configured as buffered, unbuffered, or VDD inputs. The parts incorporate a power-on reset circuit, which ensures that the DAC outputs power up to 0 V and remain there until a valid write to the device takes place. The outputs of all DACs may be updated simultaneously using the asynchronous LDAC input. The parts contain a power-down feature that reduces the current consumption of the devices to 400 nA at 5 V (120 nA at 3 V). The eight channels of the DAC may be powered down individually.

All three parts are offered in the same pinout, which allows users to select the resolution appropriate for their application without redesigning their circuit board.
