DESCRIPTION
The 3650 and 3652 are optically coupled integrated circuit isolation amplifiers. Prior to their introduction commercially available isolation amplifiers had been modular or rack mounted devices using transformer c o u p l e d modulation demodulation techniques. Compared to these earlier isolation amplifiers, the 3650 and 3652 have the advantage of smaller size,
6 4 1.6M 8 RG1
lower cost, wider bandwidth and integrated circuit reliability. Also, because they use a DC analog modulation technique as opposed to a carrier-type techn i q u e , they avoid the problems of electromagnetic interference (both transmitted and received) that most of the modular isolation amplifiers exhibit.

NOTES: (1) All electrical and mechanical specifications of the 3650MG and 3652MG are identical to the 3650HG and 3652HG, respectively, except that the following specifications apply to the 3650MG and 3652MG: (a) Isolation test voltage duration increased from 10 seconds minimum to 60 seconds minimum; (b) Input offset voltage at 25°C, max: ±10mV; vs temperature max: ±100µV/°C; (c) Output offset voltage at 25°C, max; ±50mV; vs temperature max; ±1.8mV/°C. (2) If used as 3650, see Installation and Operating Instructions. (3) Trimmable to zero. (4) Gain error terms specified for inputs applied through buffer amplifiers (i.e., ±1 or ±IR pins). (5) Input stage specifications at +I and I inputs for 3652 unless otherwise noted. (6) Maximum safe input current at either input is 10mA. (7) Continuous rating is 1/3 pulse rating. (8) Load current is drawn from one supply lead at a time: other supply current at quiescent level. For 3652 add 0.2mA/V of positive CMV. (9) dT/dt < 1°C/minute below 0°C, and long-term storage above 100°C is not recommended. Also limit the repeated thermal cycles to be within the 0°C to +85°C temperature range.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
