Product Summary

The DAC8534 is a quad channel, 16-bit Digital-to-AnalogConverter (DAC) offering low-power operation and a flexibleserial host interface. Each on-chip precision output amplifierallows rail-to-rail output swing to be achieved over the supplyrange of 2.7V to 5.5V. The device supports a standard 3-wireserial interface capable of operating with input data clockfrequencies up to 30MHz for IOVDD = 5V.The DAC8534 requires an external reference voltage to setthe output range of each DAC channel. Also incorporatedinto the device is a power-on reset circuit which ensures thatthe DAC outputs power up at zero-scale and remain thereuntil a valid write takes place. The DAC8534 provides a perchannel power-down feature, accessed over the serial inter-face, that reduces the current consumption to 200nA perchannel at 5V.The low-power consumption of this device in normal opera-tion makes it ideally suited to portable battery-operatedequipment and other low-power applications. The powerconsumption is 5mW at 5V, reducing to 4μW in power-downmode.The DAC8534 is available in a TSSOP-16 package with aspecified operating temperature range of –40°C to +105°C.
