„ DESCRIPTION
The AA88368AP is an 10-bit resolution digital to analog converter (DAC),
designed for interface with 10 bits micro-controller. The AA88368AP 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 20DŽs settling time. AA88368AP is a single 5V
power DAC. Output could be full swing as the analog power is equal to the system
power.
The AA88368AP 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 AA88368AP is suitable for electronic volumes and
replacement for potentiometers for adjustment, in addition to normal D/A converter
applications.
AA88368AP is a 20 pins SSOP package. Its operation temperature range is
specified over -10Ċ to 75Ċ. Figure 2 shows its pin assignment.
