AD1555/AD1556 ABSOLUTE MAXIMUM RATINGS1
Junction Temperature . 150°C Analog Inputs Storage Temperature . –65°C to +150°C Pins 7, 8, 23, 24, 25, 28 . –VA – 0.3 V to +VA + 0.3 V Lead Temperature Range AIN(+), AIN(–) DC Input Current . ± 100 mA (Soldering 10 sec) . 300°C AIN(+), AIN(–) 2 µs Pulse Input Current . ± 1.5 A NOTES Supply Voltages 1Stresses above those listed under Absolute Maximum Ratings may cause perma- +VA to –VA . –0.3 V to +14 V nent damage to the device. This is a stress rating only; functional operation of the +V device at these or any other conditions above those indicated in the operational A to AGND . –0.3 V to +7 V –V section of this specification is not implied. Exposure to absolute maximum rating A to AGND . –7 V to +0.3 V conditions for extended periods may affect device reliability. VL to DGND . –0.3 V to +7 V 2Specification is for device in free air: Ground Voltage Differences 28-lead PLCC: θJA = 36°C/W, θJC = 20°C/W DGND, AGND1, AGND2, AGND3 . ± 0.3 V 44-lead MQFP: θJA = 36°C/W, θJC = 14°C/W Digital Inputs . –0.3 V to VL + 0.3 V Internal Power Dissipation2 AD1555 . 1.8 W AD1556 . 1.8 W
