Channel Separation Test Circuit APPLICATIONS INFORMATION Battery-Powered Applications The OP490 can be operated on a minimum supply voltage of 1.6 V, or with dual supplies of ±0.8 V, and draws only 60 mA of supply current. In many battery-powered circuits, the OP490 can be continuously operated for hundreds of hours before requiring battery replacement, reducing equipment downtime, and operating costs. High performance portable equipment and instruments fre- quently use lithium cells because of their long shelf-life, light weight, and high energy density relative to older primary cells. Most lithium cells have a nominal output voltage of 3 V and are noted for a flat discharge characteristic. The low supply current HOURS 4 3 0 0 1750 250 500 750 2 1 1000 1500 Figure 4. Lithium-Sulphur Dioxide Cell Discharge Charac- teristic with OP490 and 100 k W Loads requirement of the OP490, combined with the flat discharge characteristic of the lithium cell, indicates that the OP490 can be operated over the entire useful life of the cell. Figure 4 shows the typical discharge characteristic of a 1 Ah lithium cell power- ing an OP490 with each amplifier, in turn, driving full output swing into a 100 k W load. Single-Supply Output Voltage Range In single-supply operation the OP490’s input and output ranges include ground. This allows true “zero-in, zero-out” operation. The output stage provides an active pull-down to around 0.8 V above ground. Below this level, a load resistance of up to 1 M W to 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. Input Voltage Protection The OP490 uses a PNP input stage with protection resistors in series with the inverting and noninverting inputs. The high breakdown of the PNP transistors coupled with the protection resistors provides a large amount of input protection, allowing the inputs to be taken 20 V beyond either supply without dam- aging the amplifier. |
