... Rev 0; 1/02 Quad, 10-Bit, Low-Power, 2-Wire, Serial General Description The MAX5841 is a quad, 10-bit voltage output, digital- to-analog converter (DAC) with an I 2-wire interface that operates at clock rates up to 400kHz. The device operates from a single 2.7V to 5.5V supply and draws only 230µ down mode decreases current consumption to less than 1µ ...

... V and SCL facilitate bidirectional communication between Output Buffer the MAX5841 and the master at rates up to 400kHz. Figure 1 shows the 2-wire interface timing diagram. The MAX5841 is a transmit/receive slave-only device, rely- ing upon a master to generate a clock signal. The mas- ter (typically a microcontroller) initiates data transfer on the bus and generates SCL to permit that transfer ...

... The LSB of the address word is the Read/Write (R/W) bit. R/W indicates whether the master is writing to or read- ing from the MAX5841 (R selects the write condi- tion, R selects the read condition). After receiving the proper address, the MAX5841 issues an ACK by pulling SDA low for one clock cycle ...

... PD0 and PD1 (Table 1). Any combination of the four DACs can be controlled with a single write sequence. In read mode (R/W = 1), the MAX5841 writes the con- tents of the DAC register to the bus. The direction of data flow reverses following the address acknowledge by the MAX5841 ...
