DA9186.001 29 January, 2004 MAS9186 8 X 8-bit D to A Converter This is preliminary information on a new product under development. Micro Analog Systems Oy reserves the right to make any changes without notice. • 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. FEATURES • • • • • 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. APPLICATIONS • • • Eight 8-bit DACs on a single monolithic chip Voltage level output TSSOP 16 package Single +2.7V supply Power-on reset High resolution monitors Automatic gain control Trimmer replacement BLOCK DIAGRAM SDI CLK 11-bit Shift Register MAS9186A2 8-bit data 8-BIT DAC O7 8-BIT DAC 8-BIT DAC 8-BIT DAC 8-BIT DAC 8-BIT DAC VDD VREFH VREFL (XRESET in MAS9186A1) O4 O3 8-BIT DAC Address Decoder O6 O5 8-BIT DAC XCS O8 O2 O1 GND 1 (9) DA9186.001 29 January, 2004 PIN CONFIGURATION 16 VDD 2 15 XRESET O2 3 14 08 O3 4 O4 5 O5 O6 6 XSHDN 8 7 O2 3 O3 4 13 O7 12 SDI 10 GND O4 5 O5 6 O6 7 XCS XSHDN 8 11 CLK 9 16 VDD VREFH 1 O1 2 15 O8 14 O7 MAS9186A2 YYWW 1 MAS9186A1 YYWW VREFH O1 13 SDI 12 CLK 11 VREFL 10 GND 9 XCS Top view YYWW = year, week PIN DESCRIPTION Pin Number MAS9186 A1 MAS9186 A2 Function 1 VREFH VREFH DAC output reference high voltage 2 O1 O1 DAC 1, address 0x0 3 O2 O2 DAC 2, address 0x1 4 O3 O3 DAC 3, address 0x2 5 O4 O4 DAC 4, address 0x3 6 O5 O5 DAC 5, address 0x4 7 O6 O6 DAC 6, address 0x5 8 XSHDN XSHDN Device analog part power-down signal (active low) 9 XCS XCS Device enable signal (rising edge loads data to DAC) 10 GND GND Device ground-pin 11 CLK VREFL Data clock / DAC output low reference voltage 12 SDI CLK Serial input data / Data clock 13 O7 SDI DAC 7, address 0x6 / Serial input data 14 O8 O7 DAC 8, address 0x7 / DAC 7, address 0x6 15 XRESET O8 Device Digital part reset – middle code preset pin/DAC 8, address 0xB 16 VDD VDD Device power supply pin MAS9186 has two bonding options available: • • MAS9186A1, where VREFL pin is bonded to GND pin and XRESET pin can be used MAS9186A2, where XRESET pin is bonded to VDD pin and VREFL pin can be used 2 (9) DA9186.001 29 January, 2004 ABSOLUTE MAXIMUM RATINGS Parameter Symbol Power Supply (VDD to GND) Conditions VDD Input Voltage Range (any other pin) Min Max Unit -0.3 +6.0 V -0.3 VDD + 0.3 V 1000 mW +150 °C Continuous Power Dissipation Storage Temperature Range -65 RECOMMENDED OPERATION CONDITIONS Parameter Symbol Supply Voltage Range Operating Temperature Range Conditions VDD Temp Min Typ Max Unit 2.7 -40 3.6 5.5 +85 °C V ELECTRICAL CHARACTERISTICS (VDD = 3.0 V ± 10% or 5.0 V ± 10%, VREFH = VDD, VREFL = 0V, -40°C ≤ TA ≤ +85°C unless otherwise noted) DC Parameters ◆ Digital Inputs Parameter Symbol DAC Resolution Conditions Min N Typ Max 8 Unit Bits DAC Differential Nonlinearity Error DNL -1 +1 LSB DAC Integral Nonlinearity Error INL -1 +1 LSB DAC Full-scale Error GFSE -1 +1 LSB DAC Zero Code Error BZSE -1 +1 LSB DAC Output Resistance ROUT 60 Ω Max Unit 30 ◆ Reference Input Parameter Symbol Conditions Min REFH Voltage Range VREFH VREFH > VREFL 0 VDD REFL Voltage Range (MAS9186A2 only) VREFL VREFH > VREFL 0 VDD REFH Input Resistance RREFH REFL Input Resistance RREFL 5 Typ 10 kΩ 10 kΩ 3 (9) DA9186.001 29 January, 2004 ◆ Digital Input Parameter Symbol Conditions Min Typ Max Digital Logic High VIH Digital Logic Low VIL 0.3*VDD Digital Input Current IIL ±1 Unit 0.7*VDD uA ◆ Power Supplies Parameter Symbol Conditions Power Supply Range VDD Supply Current IDD VDD = 3.60V Supply Current IDD VDD = 5.50V Shutdown Current Min Typ 2.7 3 ISHDN 0.5 Max Unit 5.5 V 6 mA 20 mA 5 uA AC Parameters ◆ AC Characteristics Dynamic Performance Parameter Power Supply Sensitivity (100Hz) Symbol Conditions Min Typ Max Unit PSRR 54 dB Vout Settling time (±1/2 LSB error band) TS 6 µs Crosstalk between adjacent outputs CT 63 dB Switching Characteristics o (Minimum values at +25 C, VDD = 3.60 V) Parameter Symbol Conditions Min Typ Max Unit Input Clock High Pulse Width TCH 16 ns Input Clock Low Pulse Width TCL 7 ns Data Setup Time TDS -5 ns Data Hold Time TDH 5 ns XCS Fall to First Clock Pulse Fall TCLCL 16 ns XCS High Pulse Width TCSW 22 ns TRS 28 ns CLK Rise to XCS Rise Hold Time TCSH 22 ns XCS Rise to CLOCK Rise Setup TCS1 -5 ns RESET Pulse Width 4 (9) DA9186.001 29 January, 2004 OPERATING MODES DAC maximum output voltage is set using VREFH and VREFL pins (= 255/256 * (VREFH-VREFL)+VREFL) (note: VREFL=GND in case of MAS9186A1). 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 stops data reading and 11 CLK-cycles are used as the input data (3 address bits and 8 data bits). The last 11 bits before rising XCS are used as input data. ◆ Timing diagram SDI A2 A1 A0 D7 D6 D5 D4 D3 D2 D1 D0 CLK XCS DAC Register Load VOUT APPLICATION AND TEST CIRCUIT INFORMATION +3.0v 16 VDD 1 VREFH MAS9186A2 8 Controller Clock 12 Data In 13 Latch 9 XSHDN CLK SDI O8 O7 XCS O6 6 5 O1 10 7 O4 O2 GND 14 O5 O3 100 nF 15 4 3 2 VREFL 11 5 (9) DA9186.001 29 January, 2004 PACKAGE (TSSOP16) OUTLINES C E D Seating Plane B F G H A O Pin 1 B Detail A B L I I1 K P Section B-B J1 M J Dimension Min Max A 6.40 BSC B 4.30 4.50 C 5.00 BSC D 0.05 0.15 E 1.10 F 0.19 0.30 G 0.65 BSC H 0.18 0.28 I 0.09 0.20 I1 0.09 0.16 J 0.19 0.30 J1 0.19 0.25 K 0° 8° L 0.24 0.26 M 0.50 0.75 (The length of a terminal for soldering to a substrate) N 1.00 REF O 12° P 12° Dimensions do not include mold flash, protrusions, or gate burrs.
