Detailed Description
The MAX5306/MAX5307 are 12-bit, eight-channel, low-
power, voltage-output digital-to-analog converters
(DACs) that are easily addressed using a simple 3-wire
serial interface. These devices feature eight double-
buffered DACs using a common 16-bit serial to parallel
shift register, a power-on reset (POR) circuit and eight
output buffer amplifiers.
Figure 1 shows the block diagram of MAX5306/
MAX5307. The shift register converts a serial 16-bit
word to parallel data for each input register operating
with a clock rate of up to 15MHz. The 3-wire digital
interface to the shift register consist of chip-select (CS),
serial clock (SCLK), and data input (DIN). Serial data at
DIN is loaded on the falling edge of SCLK.
The eight double-buffered DACs consist of input and
DAC registers. The input registers are directly connect-
ed to the shift register and hold the result of the most
recent write operation. The eight 12-bit DAC registers
hold the current output code for the respective DAC.
Data can be transferred from the input registers to the
DAC registers by either the hardware interface (LDAC)
or by software command. The output of DACs are
buffered through eight Rail-to-Rail op amps.
The MAX5306 has a digital output (DOUT) which can
be used to daisy chain multiple devices on a single ser-
ial bus. The MAX5307 contains a hardware shutdown
(CLR) to clear all internal registers and power-down all
DACs.
The MAX5306/MAX5307 require an external reference
such as the MAX6161 family. The reference voltage
range is from 0.8V to VDD.
POR circuitry gives the DACs a defined state during
startup. At power-on, the DAC outputs reset to zero
through a 100k
Ω resistor, providing additional safety for
applications that drive valves or other transducers that
need to be off at power-up.
The MAX5306/MAX5307 feature low digital feedthrough
and minimize glitch energy on MSB transitions. The 3-
wire SPI, QSPI, MICROWIRE and DSP-compatible seri-
al interface saves additional circuit board space .
Serial Interface
Configuration
The MAX5306/MAX5307 3-wire serial interface are
compatible with MICROWIRE, SPI, QSPI, and DSPs
(Figure 2 and Figure 3). The chip-select input (CS)
frames the serial data loading at DIN. Following CS’s
high-to-low transition, the data is shifted synchronously
and latched into the input register on each falling edge
of the serial clock input (SCLK). Each serial word is 16
bits, the first four bits are the control word followed by
12 data bits (MSB first) as shown in Table 1. The 12-bit
DAC code is unipolar binary with 1LSB = VREF/4096.
The serial input register transfers its contents to the
input registers after loading 16 bits of data and driving
CS high. CS must be brought high for a minimum of
20ns before the next write sequence since a write
