ZHCSGI8A April 2017 – October 2021 ADC12D1620QML-SP
PRODUCTION DATA
The ADC12D1620QML-SP has been designed for cold sparing with no reduction in operational lifetime or increase in FIT rate as long as certain conditions are met. Cold sparing is defined as a device in which all power supplies are either floating (high-impedance) or grounded. When cold sparing, all output pins must be either floating or clamped to ground through ESD diodes of the receiving device and not pulled up to an active power supply voltage. Input pins may be driven low (or grounded) or driven to other voltages as long as they are within the Recommended Operating Conditions. Input pins (digital and analog) must maintain a maximum input level of 2.15 V and maximum input current of 50 mA per pin when cold sparing. The input current at each pin is a function of the voltage applied to the pin, the ESD diode IV curve, the power down pin settings, and conditions of the V_A supply. See Figure 8-7 to Figure 8-9 for typical IV curves.
