TLC1543IN – TEXAS INSTRUMENTS

The Texas Instruments TLC1543IN is a single, rail-to-rail input/output operational amplifier (op-amp) optimized for low-power applications. Packaged in a space-saving 8-pin SOIC, it operates from a single supply voltage ranging from 2.0V to 5.5V, making it suitable for battery-powered systems. Its input common-mode voltage range extends to the negative rail, enabling full signal swing utilization. The TLC1543IN boasts a typical input bias current of only 10nA and a low input offset voltage of ±5mV (maximum), contributing to high accuracy in precision amplification circuits. Its output can swing rail-to-rail, maximizing dynamic range. This device features a high gain-bandwidth product (GBW) of 1MHz, suitable for many audio and instrumentation applications. Common use cases include precision instrumentation amplifiers, low-power signal conditioning circuits, and sensor interfaces requiring minimal power consumption and high accuracy. The TLC1543IN’s advantages lie in its combination of low power, rail-to-rail operation, and relatively high bandwidth, making it a versatile choice where space and power are limited but precision is critical. Its low input bias current minimizes errors stemming from high impedance sources.
