ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS—MAX5231

(VDD = +4.5V to +5.5V, OS_ = AGND = DGND = 0, RL = 5k

Ω, CL = 100pF, TA = TMIN to TMAX, unless otherwise noted. Typical values

are at TA = +25°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.

VDD to AGND, DGND ...............................................-0.3V to +6V

AGND to DGND.....................................................-0.3V to +0.3V

Digital Inputs to DGND.............................................-0.3V to +6V

Digital Output (DOUT) to DGND...................-0.3V to VDD + 0.3V

OUT_ to AGND .............................................-0.3V to VDD + 0.3V

OS_ to AGND...................................................-4V to VDD + 0.3V

Maximum Current into Any Pin............................................50mA

Continuous Power Dissipation (TA = +70°C)

16-Pin QSOP (derate 8.3mW/°C above +70°C)...........667mW

Operating Temperature Range ...........................-40°C to +85°C

Storage Temperature Range .............................-65°C to +150°C

Lead Temperature (soldering, 10s) .................................+300°C
