This video shows three unusual application circuit examples of Touchstone Semiconductor’s 0.8V, 600nA operational amplifier, the TS1001. First, the TS1001 is used to build a 1-Hz, 800nA relaxation oscillator. A second example shows how the TS1001, with the help of a logic-level PMOS, is being used as a low-power peak detector and, in the final example, the TS1001 is configured to create a very linear voltage-to-current convertor, using just one external resistor. In addition to the single-amplifier TS1001, Touchstone Semiconductor also offers the dual TS1002 and the quad TS1004.
