■ General 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
20μs 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 -10℃ to 75℃. Figure 2 shows its pin assignment.
