Page 1
... TS1001 is Touchstone’s first operational amplifier in the “NanoWatt Analog™” high-performance analog integrated circuits portfolio. The TS1001 exhibits a typical input offset voltage of 0.5mV, a typical input bias current of 25pA, and rail- to-rail input and output stages. The TS1001 can operate from single-supply voltages from 0 ...

... Figure 3. Figure 3: A Nanopower 2-Pole Sallen-Key Low-Pass Filter. For best results, the filter’s cutoff frequency should times lower than the TS1001’s crossover frequency. Additional operational amplifier phase margin shift can be avoided if the amplifier bandwidth-to-signal bandwidth ratio is greater than 8 ...

... The effect is quite evident when the transient response is observed as there will appear noticeable peaking/ringing in the output transient response. If the TS1001 is used in an application that requires driving larger capacitive loads, an isolation resistor between the output and the capacitive load should be used as illustrated in Figure 5. ...

... TS1001 Configuring the TS1001 as Nanowatt Analog Comparator Although optimized for use as an operational amplifier, the TS1001 can also be used as a rail-to- rail I/O comparator as illustrated in Figure 7. Figure 7: A NanoWatt Analog Comparator with User- Programmable Hysteresis. External hysteresis can be employed to minimize the risk of output oscillation. The positive feedback circuit causes the input threshold to change when the output voltage changes state ...
