ABSOLUTE MAXIMUM RATINGS
DVCC, VCC to GND................................................-0.3V to +6.0V
RIN, CIN, DATA, DDRV,
SHDN to GND ......................................-0.3V to (DVCC + 0.3V)
RST, CLK, IO to GND ................................-0.3V to (VCC + 0.3V)
Continuous Power Dissipation (TA = +70°C)
10-Pin µMAX (derate 5.6mW/°C above +70°C) ..........444mW
Operating Temperature Range ..........................-40°C to +85°C
Storage Temperature Range ............................-65°C to +150°C
Junction Temperature ......................................................+150°C
Lead Temperature (soldering, 10s) ................................+300°C
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(Figure 1, DVCC = +1.8V, VCC = +3.0V or +5.0V, SHDN = DVCC, CIN = RIN = GND or DVCC, IO = VCC, DATA = DDRV = DVCC,
CIO = CCLK = CRST = CDATA = 30pF, TA = 0°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)
