• Manufacturer Part Number: MAX5360
• Description: Low-Cost, Low-Power 6-Bit DACs with 2-Wire Serial Interface in SOT23 Package
• Manufacturer: MAXIM [Maxim Integrated Products]

The MAX5360/MAX5361/MAX5362 are compatible with
existing I
ance inputs; SDA has an open drain that pulls the data
line low during the 9th clock pulse. Figure 7 shows a

general call address is ignored, and CBUS formats are
not supported. The MAX5360/MAX5361/MAX5362
address is compatible with the 7-bit I
protocol only. No 10-bit formats are supported.
RESTART protocol is supported, but an immediate
STOP condition is necessary to update the DAC.
The serial 2-wire interface has logic levels defined as
V
include Schmitt-trigger buffers to accept slow-transition
interfaces. This means that optocouplers can interface
directly to the MAX5360/MAX5361/MAX5362 without
additional external logic. The digital inputs are compati-
ble with CMOS logic levels and must not be driven with
voltages higher than V
Careful PC board layout is important for best system
performance. To reduce crosstalk and noise injection,
keep analog and digital signals separate. Ensure that
the ground return from GND to the supply ground is
short and low impedance; a ground plane is recom-
mended. Bypass V
as possible to the device. If the supply is excessively
noisy, connect a 10Ω resistor in series with the supply
