5 / 79 page  www.ti.com ABSOLUTE MAXIMUM RATINGS THERMAL CHARACTERISTICS (1) DAC5687 SLWS164E – FEBRUARY 2005 – REVISED SEPTEMBER 2006 TERMINAL FUNCTIONS (continued) TERMINAL I/O DESCRIPTION NAME NO. SLEEP 96 I Asynchronous hardware power-down input. Active-High. Internal pulldown. TXENABLE has two purposes. In all modes, TXENABLE must be high for the DATA to the DAC to be enabled. When TXENABLE is low, the digital logic section is forced to all 0, and any input data presented to DA[15:0] and DB[15:0] is ignored. In interleaved data mode, when the qflag register TXENABLE 33 I bit is cleared, TXENABLE is used to synchronizes the data to channels A and B. The first data after the rising edge of TXENABLE is treated as A data, while the next data is treated as B data, and so on. TESTMODE 97 I TESTMODE is DGND for the user over operating free-air temperature range (unless otherwise noted) (1) UNIT AVDD(2) –0.5 V to 4 V DVDD(3) –0.5 V to 2.3 V Supply voltage range CLKVDD(2) –0.5 V to 4 V IOVDD(2) –0.5 V to 4 V PLLVDD(2) –0.5 V to 4 V Voltage between AGND, DGND, CLKGND, PLLGND, and IOGND –0.5 V to 0.5 V AVDD to DVDD –0.5 V to 2.6 V DA[15:0](4) –0.5 V to IOVDD + 0.5 V DB[15:0](4) –0.5 V to IOVDD + 0.5 V SLEEP(4) –0.5 V to IOVDD + 0.5 V CLK1/2, CLK1/2C(3) –0.5 V to CLKVDD + 0.5 V Supply voltage range RESETB(4) –0.5 V to IOVDD + 0.5 V LPF(4) –0.5 V to PLLVDD + 0.5 V IOUT1, IOUT2(2) –1 V to AVDD + 0.5 V EXTIO, BIASJ(2) –0.5 V to AVDD + 0.5 V EXTLO(2) –0.5 V to IAVDD + 0.5 V Peak input current (any input) 20 mA Peak total input current (all inputs) 30 mA TA Operating free-air temperature range (DAC5687I) –40 °C to 85°C Tstg Storage temperature range –65 °C to 150°C Lead temperature 1,6 mm (1/16 inch) from the case for 10 seconds 260 °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 AGND. (3) Measured with respect to DGND. (4) Measured with respect to IOGND. over operating free-air temperature range (unless otherwise noted) Thermal Conductivity 100 HTQFP UNIT TJ Junction temperature(2) 105 °C Theta junction-to-ambient (still air) 19.88 °C/W θ JA Theta junction-to-ambient (150 lfm) (0.762 m/s) 14.37 °C/W (1) Air flow or heat sinking reduces θ JA and is highly recommended. (2) Air flow or heat sinking required for sustained operation at 85 °C and maximum operating conditions to maintain junction temperature.
