8 Application and Implementation

Note

implementation to confirm system functionality.

8.1 Application Information

The TLVx365 offer outstanding dc and ac performance. These devices operate with up to a 5.5-V power supply,

offer an ultra-low input bias current and a 50-MHz bandwidth with true rail-to-rail input capability.

8.1.1 Overdrive Recovery Performance

The TLVx365 family exhibits excellent overdrive recovery when the output is driven well beyond the V+ or V–

supplies. When configured in a low-side current-sensing configuration (see Figure 8-1), the output of the op amp

(TLVx365) is often driven to or less than ground as a result of ground bounce at the power ground or the ≤ 0-A

current being measured across shunt resistance RSH. The TLVx365 has the ability to recover from an overdrive

event in < 100 ns. Figure 8-2 shows the comparison of the overdrive recovery performance of TLVx365 and

other popular op amps in the same category.
