... OP490’s output swing also includes ground when operating from a single supply, enabling “zero-in, zero-out” operation. The quad OP490 draws less than quiescent supply current per amplifier, but each amplifier is able to deliver over output current to a load. Input offset voltage is under 0.5 mV with offset drift below 5 mV/∞ ...

... The output stage provides an active pull-down to around 0.8 V above ground. Below this level, a load resistance ground is required to pull the output down to zero. In the region from ground to 0.8 V, the OP490 has voltage gain equal to the data sheet specification. Output current source capability is maintained over the entire voltage range including ground ...

... OP490 Micropower Voltage-Controlled Oscillator An OP490 in combination with an inexpensive quad CMOS switch comprise the precision V of Figure 5. This circuit CO provides triangle and square wave outputs and draws only 75 mA from supply. A acts as an integrator; S1 switches the charging current symmetrically to yield positive and negative ramps ...
