1 If the analog inputs are driven from alternative VDD and VSS supply circuitry,

a 240 Ω series resistor should be placed on the analog inputs and Schottky

diodes should be placed in series with the AD7656-1/AD7657-1/AD7658-1’s

VDD and VSS supplies.

2 Transient currents of up to 100 mA do not cause SCR latch-up.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

THERMAL RESISTANCE

θJA is specified for the worst-case conditions, that is, a device

soldered in a circuit board for surface-mount packages. These

specifications apply to a 4-layer board.
