MAX1932 Digitally Controlled, 0.5% Accurate, Safest APD Bias Supply
Absolute Maximum Ratings
VIN to GND...-0.3V to +6V Operating Temperature Range ...-40°C to +85°C DIN, SCLK, CS, FB to GND ..-0.3V to +6V Junction Temperature ..+150°C COMP, DACOUT, GATE, CL to GND ...-0.3V to (VIN +0.3V) Storage Temperature Range ...-65°C to +150°C CS+, CS- to GND ...-0.3V to +110V Lead Temperature (soldering 10s) ..+300°C Continuous Power Dissipation (TA = +70°C) 12-Pin Thin QFN (derate 16.9mW/°C above +70°C) .1349mW 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
(VIN = 3.3V, CS = SCLK = DIN = 3.3V, CS+ = CS- = 45V, Circuit of Figure 2,
TA = 0°C to +85°C
