Quad, Serial 8-Bit DACs with Rail-to-Rail Outputs
_______________General Description
The MAX509/MAX510 are quad, serial-input, 8-bit volt-
age-output digital-to-analog converters (DACs). They
operate with a single +5V supply or dual ±5V supplies.
Internal, precision buffers swing rail-to-rail. The refer-
ence input range includes both supply rails.
The MAX509 has four separate reference inputs, allow-
ing each DAC's full-scale range to be set independently.
20-pin DIP, SSOP, and SO packages are available. The
MAX510 is identical to the MAX509 except it has two ref-
erence inputs, each shared by two DACs. The MAX510
is housed in space-saving 16-pin DIP and SO packages.
The serial interface is double-buffered: A 12-bit input
shift register is followed by four 8-bit buffer registers and
four 8-bit DAC registers. A 12-bit serial word is used to
load data into each register. Both input and DAC regis-
ters can be updated independently or simultaneously
with single software commands. Two additional asyn-
chronous control pins provide simultaneous updating
(LDAC)or clearing (CLR)of input and DAC registers.
The interface is compatible with MicrowireTMand SPI/
QSPITM. All digital inputs and outputs are TTL/CMOS
compatible. A buffered data output provides for read-
back or daisy-chaining of serial devices.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note:
The outputs may be shorted to VDD, VSS, or AGND if the package power dissipation is not exceeded. Typical short-circuitcurrent
to AGND is 50mA. Do not bias AGND more than +1V above DGND, or more than 2.5V below DGND.

Figure 1. MAX509/MAX510 3-Wire Interface Timing
_______________Detailed Description
Serial Interface

At power-on, the serial interface and all DACs are
cleared and set to code zero. The serial data output
(DOUT) is set to transition on SCLK's rising edge.
The MAX509/MAX510 communicate with microproces-
sors through a synchronous, full-duplex, 3-wire inter-
face (Figure 1). Data is sent MSB first and can be
transmitted in one 4-bit and one 8-bit (byte) packet or
in one 12-bit word. If a 16-bit control word is used, the
first four bits are ignored. A 4-wire interface adds a line
for LDACand allows asynchronous updating. The serial
clock (SCLK) synchronizes the data transfer. Data is
transmitted and received simultaneously.
Figure 2 shows a detailed serial interface timing.
Please note that the clock should be low if it is stopped
between updates. DOUT does not go into a high-
impedance state if the clock or CSis high.
Serial data is clocked into the data registers in MSB-
first format, with the address and configuration infor-
mation preceding the actual DAC data. Data is
clocked in on SCLK's rising edge while CSis low. Data
at DOUT is clocked out 12 clock cycles later, either at
SCLK's rising edge (default or mode 1) or falling edge
(mode 0).
Chip select (CS) must be low to enable the DAC. If CS
is high, the interface is disabled and DOUT remains
unchanged. CSmust go low at least 40ns before the
first rising edge of the clock pulse to properly clock in
the first bit. With CSlow, data is clocked into the
MAX509/MAX510's internal shift register on the rising
edge of the external serial clock. SCLK can be driven
at rates up to 12.5MHz.
