_______________General Description  
____________________________Features  
Single +5V or Dual 5V Suꢀꢀlꢁ ꢂꢀeraꢃion  
ꢂuꢃꢀuꢃ Buffer Amꢀlifiers Swing Rail-ꢃo-Rail  
Reference Inꢀuꢃ Range Includes Boꢃh Suꢀꢀlꢁ Rails  
Calibraꢃed ꢂffseꢃ, Gain, and Lineariꢃꢁ (1LSB TUE)  
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.  
10MHz Serial Inꢃerface, Comꢀaꢃible wiꢃh SPI, QSPI  
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.  
(CPꢂL = CPHA = 0) and MICRꢂWIRE  
Double-Buffered Regisꢃers for Sꢁnchronous  
Uꢀdaꢃing  
Serial Daꢃa ꢂuꢃꢀuꢃ for Daisꢁ-Chaining  
Power-ꢂn Reseꢃ Clears Serial Inꢃerface and Seꢃs  
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.  
All Regisꢃers ꢃo Zero

All digital inputs and outputs are  
TTL/CMOS compatible. A buffered data output provides  
for readback or daisy-chaining of serial devices.
