_______________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.

he interface is compatible with MICROWIRE

and

SPI/QSPI

. All digital inputs and outputs are

TTL/CMOS compatible. A buffered data output provides

for readback or daisy-chaining of serial devices.

Quad, Serial 8-Bit DACs with Rail-to-Rail Outputs between updates. DOUT does not go into a highimpedance state if the clock or CS is high. Serial data is clocked into the data registers in MSBfirst format, with the address and configuration information preceding the actual DAC data. Data is clocked in on SCLK's rising edge while CS is 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).

The outputs can swing from VSS to VDD. With a 0V to +4V (or +4V to 0V) output transition, the amplifier outputs will settle to 1/2LSB in typically 6µs when loaded with 10kΩ in parallel with 100pF.
