4 / 55 page  DAC5688 SLLS880B – DECEMBER 2007 – REVISED MAY 2010 www.ti.com ABSOLUTE MAXIMUM RATINGS over operating free-air temperature range (unless otherwise noted) (1) VALUE UNIT Supply Voltage Range DVDD(2) –0.5 to 2.3 V VFUSE(2) –0.5 to 2.3 V CLKVDD(2) –0.5 to 2.3 V AVDD(2) –0.5 to 4 V IOVDD(2) –0.5 to 4 V Supply Voltage Range AVDD to DVDD –2 to 2.6 V CLKVDD to DVDD –0.5 to 0.5 V IOVDD to AVDD –0.5 to 0.5 V CLK2, CLK2C(2) –0.5 to CLKVDD + 0.5 V CLKO_CLK1, LOCK_CLK1C, SLEEP, TXENABLE(2) –0.5 to IOVDD + 0.5 V DA[15..0] ,DB[15..0] (2) –0.5 to IOVDD + 0.5 V SDO, SDIO, SCLK, SDENB, RESETB (2) –0.5 to IOVDD + 0.5 V IOUTA1/B1, IOUTA2/B2 (2) –0.5 to AVDD + 0.5 V LPF, EXTIO, EXTLO, BIASJ (2) –0.5 to AVDD + 0.5 V Peak input current (any input) 20 mA mA Peak total input current (all inputs) –30 mA mA Operating free-air temperature range, TA: DAC5688I –40 to 85 °C Storage temperature range –65 to 150 °C (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) Measured with respect to GND. THERMAL INFORMATION DAC5688 THERMAL CONDUCTIVITY UNITS 64ld QFN TJ Maximum junction temperature (1)(2) 125 °C qJA Theta junction-to-ambient thermal resistance (still air) 22 Theta junction-to-ambient thermal resistance (200 lfm) 15 °C/W yJT Psi junction-to-top of package characterization parameter 0.2 qJB Theta junction-to-board characterization parameter 3.5 (1) Air flow or heat sinking reduces qJA and may be required for sustained operation at 85°C under maximum operating conditions. (2) It is strongly recommended to solder the device thermal pad to the board ground plane. 4 Submit Documentation Feedback Copyright © 2007–2010, Texas Instruments Incorporated Product Folder Link(s): DAC5688 |
