a small-signal diode (D1) as shown in Figure 1. If the
analog signal can dip below GND, add D2. Adding
protection diodes reduces the analog range to a diode
drop (about 0.7V) below V+ (for D1), and a diode drop
above ground (for D2). On-resistance increases slightly
at low supply voltages. Maximum supply voltage (V+)
must not exceed +6V.
Adding protection diode D2 causes the logic threshold
to be shifted relative to GND. TTL compatibility is not
guaranteed when D2 is added.
Protection diodes D1 and D2 also protect against some
overvoltage situations. With Figure 1’s circuit, if the sup-
ply voltage is below the absolute maximum rating, and
if a fault voltage up to the absolute maximum rating is
applied to an analog signal pin, no damage will result.
