| Agamem Microelectronics Inc. PRELIMINARY DESCRIPTION AA88347L 8-BIT DAC The AA88347L is a CMOS processed digital to analog converter (DAC) with 8-bit resolotion, low leakage and operating current. The AA88347L 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 is converted into an analog DC voltage in the range from VSS to VDD with 8-bit resolution in one of the 8 channels by the D/A converter in a max. 200s settling time. AA88347L 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, AA88347L is also available for electronic volume and instead of potentio- meters for adjustment due to its high stability on the capacitive load.16 pins TSSOP package type are available for AA88347L. Its operational temper- nature range is specified over -20 to 85. FEATURES * 12 bits serial data input (3 wire serial data transfer method, DI, CLK, LD) * R-2R resistor ladder used for D/A conversion * 8 channels with 8-bit resolution monotonic D/A converter * 8 channels buffer operational amplifiers operating in the full voltage range from VCC to GND only if VDD=VCC and VSS=GND * Max. 2.5 MHz serial digital data input * Serial I/O for cascade application * Max. 1.0 mA output drive/sink current * Two separate power supply/ground lines for system and analog power supply * Single +3 V system power supply APPLICATION DVD, CD-R, CD-RW, DVC, digital camera, and other industrial equipments (c)Copyright Agamem Microelectronics Inc. 1 www.agamem.com.tw 2008/12/31 AGAMEM MICROELECTRONICS INCOPERATION RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
