MAX5106EEE
Nonvolatile, Quad, 8-Bit DACs
General Description
The MAX5105/MAX5106 nonvolatile, quad, 8-bit digital-
to-analog converters (DACs) operate from a single
+2.7V to +5.5V supply. An internal EEPROM stores the
DAC states even after power is removed. Data from
these nonvolatile registers automatically initialize the
DAC outputs and operating states during power-up.
Precision internal buffers swing Rail-to-Rail®, and the
reference input range includes both ground and the
positive rail.
The MAX5105/MAX5106 feature a software-controlled
10µA shutdown mode and a mute state that drives the
DAC outputs to their respective REFL_ voltages. The
MAX5105 includes an asynchronous MUTE input, as
well as a RDY/BSYoutput that indicates the status of
the nonvolatile memory.
The MAX5105 is available in a 20-pin QSOP and 20-pin
wide SO packages, and the MAX5106 is available in a
16-pin QSOP package.

Detailed Description
The MAX5105/MAX5106 quad, 8-bit DACs feature an
internal, nonvolatile EEPROM, which stores the DAC
states for initialization during power-up. These devices
consist of four resistor string DACs, four rail-to-rail
buffers, a 14-bit shift register, oscillator, power-on reset
(POR) circuitry, and five volatile and five nonvolatile
memory registers (Functional Diagram). The shift regis-
ter decodes the control and address bits, routing the
data to the proper memory registers. Data can be writ-
ten to a selected volatile register, immediately updating
the DAC output, or can be written to a selected non-
volatile register for storage.
The five volatile registers retain data as long as the
device is enabled and powered. Once power is
removed or the device is shut down, the volatile regis-
ters are cleared. The nonvolatile registers retain data
even after power is removed. On power-up, the POR
circuitry and internal oscillator control the transfer of
data from the nonvolatile registers to the volatile regis-
ters, which automatically initializes the device upon
startup. Data can be read from the nonvolatile registers
through DOUT.

DAC Operation
The MAX5105/MAX5106 use a matrix decoding archi-
tecture for the DACs, which saves power in the overall
system. A resistor string placed in a matrix fashion
divides down the difference between the external refer-
ence voltages, VREFHand VREFL. Row and column
decoders select the appropriate tab from the resistor
string, providing the needed analog voltages. The
resistor string presents a code-independent input
impedance to the reference and guarantees a monoto-
nic output. Figure 1 shows a simplified diagram of one
of the four DACs.
Output Buffer Amplifiers
All MAX5105/MAX5106 analog outputs are internally
buffered by precision unity-gain followers that slew at
about 0.5V/µs. The outputs can swing from GND to
VDD. With a VREFL_ to VREFH_ (or VREFH_to VREFL_)
output transition, the amplifier outputs typically settle to
±1/2LSB in 6µs when loaded with 10kΩin parallel with
100pF.
The software mute/shutdown command independently
drives each output to its respective REFL_ voltage
Placing all four DACs in shutdown reduces supply cur-
rent to 10µA (max). The MAX5105 also provides an
asynchronous MUTE input, simultaneously driving all
DAC outputs to their respective REFL_ voltages.
Internal EEPROM
The MAX5105/MAX5106 internal EEPROM consists of
five nonvolatile registers that retain the DAC output and
operating states after the device is powered down.
Four registers store data for each DAC, and one stores
the mute and shutdown states for the device.
DAC Registers
The MAX5105/MAX5106 have eight 8-bit DAC regis-
ters, four volatile and four nonvolatile, that store DAC
data. The four volatile DAC registers hold the current
value of each DAC. Data is written to these registers in
two ways: directly from DIN or loaded from the respec-
tive nonvolatile registers (see Serial Input Data Format
and Control Codes). These registers are cleared when
the device is shut down or power is removed.
The four nonvolatile registers retain the DAC values
even after power is removed. Stored data is accessed
in two ways: transferring data to a volatile register to
update the respective DAC output or reading data
through DOUT (see Serial Input Data Format and
Control Codes). On power-up, the device is automati-
cally initialized with data stored in the nonvolatile regis-
ters.
Mute/Shutdown Registers
The MAX5105/MAX5106 have two 8-bit mute/shutdown
registers that store the operating state of each DAC.
The four MSBs hold the mute states, and the four LSBs
hold the shutdown states (Table 1). The volatile regis-
ters hold the current mute/shutdown state of each DAC.
Like the DAC registers, the nonvolatile mute/shutdown
register maintains its data after the device is powered
down, and the contents can be read on DOUT. The
volatile register is initialized with the nonvolatile data on
power-up and can be loaded through DIN or from the
nonvolatile register (see Serial Input Data Format and
Control Codes).
