MAS9188

DA9188.002 23 February 2005 MAS9188 12 × 8-Bit D to A Converter 3-Pin Serial Data Interface Low Voltage Output Buffer Replaces 12 Potentiometers Individually Programmable Outputs • Fully Operational Down to 1.2 V • • • • DESCRIPTION MAS9188 is 12-channel 8-bit DAC, designed primarily for trimmer replacement. The device is controlled by a simple 3-line input. The DAC is selected with the four first bits in the serial input data (SDI-pin) and the DAC output value is set according to the last 8 bits in the serial input data.

The XRESET pin is used for middle code preset: DAC registers are reset and middle code will appear at the DAC output. Serial input data is written to SDI while XCS is low. Data is read at CLK rising edge to on-chip shift register. Rising XCS-pin reads data and 12 CLK-cycles are used as the input data (4 address bits and 8 data bits). The last 12 bits before rising XCS are used as input data. ◆ Timing diagram SDI A3 A2 A1 A0 D7 D6 D5 D4 D3 D2 D1 D0 CLK XCS VOUT APPLICATION AND TEST CIRCUIT INFORMATION +3.0v DAC Register Load 20 VDD 1 VREFH Power On/Off MAS9188A2 8 XSHDN O12 O11 CLK SDI XCS O10 O9 O8 9 O7 O6 O5 O4 O3 19 18 17 16 15 14 7 6 5 4 3 2 Controller Clock Data In Chip Select 12 13 100 nF GND 10 O2 O1 VREFL 11 5 (10) DA9188.002 23 February 2005 PACKAGE (TSSOP-20) OUTLINES e/ 2 A VIEW B-B b E E1 c1 c 12° REF S b1 INDEX AREA GAUGE PLANE e R A 0.25 12° REF D L1 L A A2 b B B b VIEW A-A A1 Symbol A A1 A2 b b1 c c1 D E E1 e L L1 R S Min -0.05 0.85 0.19 0.19 0.09 0.09 6.40 4.30 0.50 0.09 -- Nom --0.90 -0.22 --6.50 6.4 BSC 4.40 0.65 BSC 0.60 1.00 REF -0.20 Max 1.10 0.15 0.95 0.30 0.25 0.20 0.16 6.60 4.50 0.75 --- Unit mm mm mm mm mm mm mm mm mm mm mm mm mm mm Dimensions do not include mold or interlead flash, protrusions or gate burrs.
