TC913BCPA

The TC913BCPA is one member of the TC913 series.The TC913 is the world's first complete monolithic,dual auto-zeroed operational amplifier. The TC913 sets a new standard for low-power, precision dual-operational amplifiers. Chopper-stabilized or auto-zeroed amplifiers offer low offset voltage errors by periodically sampling offset error, and storing correction voltages on capacitors.Previous single amplifier designs required two user-supplied, external 0.1F error storage correction capacitors---much too large for on-chip integration.

Features of the TC913BCPA are:(1)first monolithic dual auto-zeroed operational amplifier; (2)chopper amplifier performance without external capacitors; (3)SOIC packages available; (4)high DC gain:120dB; (5)low supply current :650A; (6)low input voltage noise(0.1 Hz to 10 Hz) :0.65Vp-p; (7)wide common-mode voltage range:VSS to VDD2V; (8)high common-mode rejection:116dB.The TC913 system benefits are apparent when contrasted with a TC7650 chopper amplifier circuit implementation. A single TC913 replaces two TC7650's and four capacitors. Five components and assembly steps are eliminated.

The absolute maximum ratings of the TC913BCPA can be summarized as:(1)total supply voltage:+18V;(2)storage temperature range:-65 to 150;(3)current into any pin:10mA;(4)operating temperature range:0 to 70;(5)lead temperature(soldering,10sec):300;(6)package power dissipation:DIP 730mW.Unused devices should be stored in conductive material.Stresses above those listed under"absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied.Junction-isolated CMOS circuits inherently contain a parasitic p-n-p-n transistor circuit. Voltages exceeding the supplies by 0.3V should not be applied to the device pins.Larger voltages can turn the p-n-p-n device on, causing excessive device power supply current and power dissipation. The TC913's power supplies should be established at the same time or before input signals are applied. If this is not possible, input current should be limited to 0.1mA to avoid triggering the p-n-p-n structure.
