DAC8534 - 2.7V to 5.5V, Quad Channel, 16-Bit, Serial Input DAC

The DAC8534 is a quad channel, 16-bit Digital-to-Analog Converter (DAC) offering low-power operation and a flexible serial host interface. Each on-chip precision output amplifier allows rail-to-rail output swing to be achieved over the supply range of 2.7V to 5.5V. The device supports a standard 3-wire serial interface capable of operating with input data clock frequencies up to 30MHz for IOV_DD = 5V.

The DAC8534 requires an external reference voltage to set the output range of each DAC channel. Also incorporated into the device is a power-on reset circuit which ensures that the DAC outputs power up at zero-scale and remain there until a valid write takes place. The DAC8534 provides a per channel power-down feature, accessed over the serial interface, that reduces the current consumption to 200nA per channel at 5V.

The low-power consumption of this device in normal operation makes it ideally suited to portable battery-operated equipment and other low-power applications. The power consumption is 5mW at 5V, reducing to 4µW in power-down mode.

The DAC8534 is available in a TSSOP-16 package with a specified operating temperature range of \x9640°C to +105°C.
