AA88347L

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 www.DataSheet4U.com one of the 8 channels by the D/A converter in a max. 200µs 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 Seri...
