APPLICATION NOTES
Refer to Section 8 for Applications Information
Interface Logic Information
The MP7542 is designed to interface as a memory-mapped
output device.
A typical system configuration is shown below. CS is the de-
coded device address, and is derived by decoding the 14 higher
order address bits. A0 and A1 are the MP7542 operation ad-
dress bits, and are decoded internally in the MP7542 to point to
the desired loading operation (i.e. load high byte, middle byte,
low byte or DAC register). See Table 1.
All data loading operations are identical to the write cycle of a
RAM.
Additionally, the CLR input allows the MP7542 DAC register
to be cleared asynchronously to 0000 0000 0000. When operat-
ing the MP7542 in a unipolar mode a CLEAR sets the DAC out-
put to zero scale output. In the bipolar mode a CLEAR causes
the DAC output to go to –V
REF
.
In summary:
1. The MP7542 DAC register can be asynchronously
cleared with the CLR input.
2. Each MP7542 requires only 4 bits of memory.
3. Any of the four basic loading operations (i.e. load low
byte data register, middle byte data register, high byte
data register or 12-bit DAC register) are accomplished
by executing a memory WRITE operation to the applica-
ble address location for the required DAC operation.
