AD7304/AD7305 CIRCUIT OPERATION The AD7304/AD7305 are 4-channel, 8-bit, voltage output DACs, differing primarily in digital logic interface and number of reference inputs. Both parts share the same internal DAC design and true rail-to-rail output buffers. The AD7304 contains four independent ...

AD7304 SERIAL DATA INTERFACE The AD7304 uses a 3-wire ( CS , SDI, CLK) SPI-compatible serial data interface. New serial data is clocked into the serial input register in a 12-bit data-word format. MSB bits are loaded first. Table 5 ...
Page 16
AD7304/AD7305 AD7305 PARALLEL DATA INTERFACE The AD7305 has an 8-bit parallel interface DB7 = MSB, DB0 = LSB. Two address bits, A1 and A0, are decoded when an active low write strobe is placed on the WR pin, see Table ...
Page 17
APPLICATIONS The AD7304/AD7305 are inherently 2-quadrant multiplying DACs. That is, they can easily be set up for unipolar output operation. The full-scale output polarity is the same as the reference input voltage polarity. In some applications, it may be necessary ...
