AA88368
10-BIT DAC
Agamem Microelectronics Inc.
DESCRIPTION
The AA88368 is a 10-bit resolution digital to analog converter (DAC), designed for interface with 10 bits
micro-controller. The AA88368 has 10 channels with operational amplifier output buffers. Digital data are input
serially in max. 10MHz by individual channel units. The latched digital data are converted into analog DC voltages
by the D/A converter in 20)s settling time. AA88368 is a single 5V power DAC. Output could be full swing as the
analog power is equal to the system power. The AA88368 has 10 operational amplifier output buffers for each
one of 10 channels. These operational amplifier output buffers are used to provide high current drive/sink
capability. The AA88368 is suitable for electronic volumes and replacement for potentiometers for adjustment, in
addition to normal D/A converter applications. AA88368 is a 20 pins SSOP package. Its operation temperature
range is specified over -10 to 75 . Figure 2 shows its pin assignment.
