www.DataSheet4U.com DA9186.001 29 January, 2004 MAS9186 This is preliminary information on a new product under development. Micro Analog Systems Oy reserves the right to make any changes without notice. 8 X 8-bit D to A Converter 3-pin Serial Data Interface Low Voltage Output Buffer DESCRIPTION MAS9186 is 8-channel 8-bit DAC, designed primarily for trimmer replacement. Device is controlled by a simple 3-line input. The output buffers operate in the entire voltage range from ground to the positive power supply rail. DAC is selected with three first bits in serial input data (SDI-pin) and the DAC output value is set according to the last 8 bits in serial input data. FEATURES Eight 8-bit DACs on a single monolithic chip Voltage level output TSSOP 16 package Single +2.7V supply Power-on reset APPLICATIONS High resolution monitors Automatic gain control Trimmer replacement BLOCK DIAGRAM SDI CLK 11-bit Shift Register MAS9186A2 8-bit data 8-BIT DAC 8-BIT DAC 8-BIT DAC 8-BIT DAC 8-BIT DAC O8 O7 O6 O5 O4 O3 XCS Address Decoder 8-BIT DAC 8-BIT DAC 8-BIT DAC O2 O1 VDD VREFH VREFL (XRESET in MAS9186A1) GND 1 (9) DA9186.001 29 January, 2004 PIN CONFIGURATION VREFH O1 O2 O3 O4 O5 O6 XSHDN 1 2 3 4 5 6 7 8 16 VDD 15 XRESET 14 08 13 O7 12 SDI 11 CLK 10 GND 9 VREFH 1 O1 2 16 VDD 15 O8 14 O7 O2 3 O3 4 O4 5 O5 6 O6 7 XSHDN 8 MAS9186A1 YYWW MAS9186A2 YYWW 13 SDI 12 CLK 11 VREFL 10 GND 9 XCS XCS Top view YYWW = year, week PIN DESCRIPTION Pin Number ...
