7.4 Device Functional Modes

7.4.1 Common-Mode Voltage Range

The input common-mode voltage range of the TLVx170 family extends 100 mV below the negative rail and within

2 V of the top rail for normal operation.

This device can operate with full rail-to-rail input 100 mV beyond the top rail, but with reduced performance within

2 V of the top rail. The typical performance in this range is summarized in Table 3.

7.4.2 Overload Recovery

Overload recovery is defined as the time required for the op amp output to recover from the saturated state to

the linear state. The output devices of the op amp enter the saturation region when the output voltage exceeds

the rated operating voltage, either resulting from the high input voltage or the high gain. After the device enters

the saturation region, the charge carriers in the output devices need time to return back to the normal state. After

the charge carriers return back to the equilibrium state, the device begins to slew at the normal slew rate. Thus,

the propagation delay in case of an overload condition is the sum of the overload recovery time and the slew

time. The overload recovery time for the TLVx170 is approximately 2 µs.
