The TC913BCOA is a dual auto-zeroed Operational Amplifier for use with strain gage 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 0.1µF error storage correction capacitors - much too large for on-chip integration. The unique TC913 architecture requires smaller capacitors, making on-chip integration possible. Microvolt offset levels are achieved and external capacitors are not required. 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.

• 120dB High DC gain
• 650µA Low supply current
