The AA88347AP 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. 1m A. Digital data (DI) input serially in a max. 2.5 MHz clock (CLK) rate. The latched 12-bit digital data is 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. 100 s settling time. AA88347AP is a single 5V 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, AA88347AP is also available for electronic volume and instead of potentiometers for adjustment due to its high stability on the capacitive load. . 16 pins TSSOP package type are available for AA88347AP. Its operational temper- nature range is specified over - 20 to 85 . 2006/7/5 .. Agamem Microelectronics Inc. 8-BIT DAC - PIN DESCRIPTION Symbol VCC GND VDD VSS CLK LD Data Input/Output D1...
