MAX5360/MAX5361/MAX5362
Low-Cost, Low-Power 6-Bit DACs with
2-Wire Serial Interface in SOT23 Package

_______________________________________________________________________________________
Detailed Description
The MAX5360/MAX5361/MAX5362 voltage-output, 6-bit
DACs offer full 6-bit performance with less than 1LSB
integral nonlinearity (INL) error and less than 1LSB dif-
ferential nonlinearity (DNL) error ensuring monotonic
performance. The devices use a simple two-wire, fast-
mode I2C-compatible serial interface that operates up
to 400kHz. The MAX5360/MAX5361/MAX5362 include
an internal reference, an output buffer, and low-current
shutdown mode, making them ideal for low-power,
highly integrated applications. Figure 1 shows the
devices’ functional diagram.
Analog Section
The MAX5360/MAX5361/MAX5362 employ a current-
steering DAC topology as shown in Figure 2. At the
core of the DAC is a reference voltage-to-current con-
verter (V/I) that generates a reference current. This cur-
rent is mirrored to 255 equally weighted current
sources. DAC switches control the outputs of these cur-
rent mirrors, so only the desired fraction of the total cur-
rent-mirror currents is steered to the DAC output. The
current is then converted to a voltage across a resistor,
and this voltage is buffered by the output buffer amplifier.
Output Voltage
Table 1 shows the relationship between the DAC code
and the analog output voltage. The 6-bit DAC code is
binary unipolar with 1LSB = (VREF / 64). The MAX5360/
MAX5361 have a full-scale output voltage of (+2V -
1LSB) and (+4V - 1LSB), respectively, set by the inter-
nal references. The MAX5362 has a full-scale output
voltage of (0.9 VDD - 1LSB). Each device accepts 8-bit
DAC codes, but the accuracy is guaranteed only for
6 bits.
Output Buffer
The DAC voltage output is an internally buffered unity-
gain follower that typically slews at ±0.4V/s. The out-
put can swing from 0 to full scale. With a 1/4 FS to 3/4
FS output transition, the amplifier outputs typically settle
to 1/2LSB in less than 5s when loaded with 10k
Ω in
parallel with 50pF. The buffer amplifiers are stable with
any combination of resistive loads >10k
Ω and capaci-
tive loads <50pF.
