TL052CDG4 – TEXAS INSTRUMENTS

The Texas Instruments TL052CDG4 is a dual low-power, JFET-input operational amplifier (op-amp) packaged in a 14-pin plastic DIP (PDIP). It’s characterized by its exceptionally low input bias current (typically 25 pA), making it ideal for applications requiring high input impedance and minimal input current offset. Operating from a ±3V to ±18V supply voltage range, the TL052CDG4 boasts a large common-mode input voltage range, extending almost to the supply rails. Its unity-gain bandwidth is typically 3 MHz, and slew rate is approximately 13V/µs. This combination of low input bias current, wide bandwidth, and relatively high slew rate makes it suitable for precision instrumentation amplifiers, active filters, and low-noise signal processing applications where high input impedance is crucial. The JFET input stage minimizes input offset voltage drift with temperature changes, improving long-term stability. While not as fast as some other op-amps, the TL052CDG4’s low noise and high input impedance are its key differentiators, making it a strong choice where signal integrity is paramount, even in low-voltage designs. The CDG4 suffix indicates a commercial temperature range operation (-40°C to +85°C).
