Texas Instruments  DAC5573IPW

The DAC5573 is a low-power, quad channel, 8-bit buffered voltage output DAC. Its on-chip precision output amplifier allows rail-to-rail output swing. The DAC5573 utilizes an I2C-compatible two-wire serial interface supporting high-speed interface mode with address support of up to sixteen DAC5573s for a total of 64 channels on the bus.

The DAC5573 requires an external reference voltage to set the output range of the DAC. The DAC5573 incorporates a power-on-reset circuit that ensures that the DAC output powers up at zero volts and remains there until a valid write takes place in the device. The DAC5573 contains a power-down feature, accessed via the internal control register, that reduces the current consumption of the device to 200 nA at 5 V.

The low power consumption of this part in normal operation makes it ideally suited to portable battery operated equipment. The power consumption is less than 3 mW at VDD=5 V reducing to 1 µW in power-down mode

The DAC5573 is available in a 16-lead TSSOP package.
