■ General Description
The AA88347LP is a CMOS processed digital to analog converter (DAC) with 8-bit
redo- lotion, low leakage current and low operating current. The AA88347LP has 8 channels
with build in operational amplifier output buffers which could operate in the full-swing
voltage range from VCC to GND and enhance the Drive/Sink ability up to max. 1mA.
Digital data(DI) input serially in a max. 2.5 MHz clock(CLK) rate. The latched 12-bit digital
data are converted into an analog DC voltage in the range from VSS to VDD with 8-bit
resolution in one of the eight channels by the D/A converter in a max. 200μs settling time.
AA88347LP is a single 3V power DAC. Analog DC output could be full voltage swing
as the analog power is equal to the system power In addition to normal D/A converter
applications, AA88347LP is also available for electronic volumes and instead of potentio -
meters for adjustment due to its high stability on the capacitive load. 16 pins TSSOP
package type are available for AA88347LP. Its operational temper- nature range is specified
over –20℃ to 85℃.
