Frequently Asked Questions
What is the input bias current of the TLC27L4CD?
The TLC27L4CD features an extremely low input bias current with a maximum of 0.0006 µA (0.6 nA) and a typical value of 0.00006 µA (60 pA) at 25°C. This ultra-low bias current makes it ideal for interfacing with high-impedance sources such as pH sensors, photodiodes, and piezoelectric transducers where even small leakage currents would introduce significant measurement errors.
What supply voltage range does the TLC27L4CD support?
The TLC27L4CD operates over a supply voltage range of 5 V to 15 V, supporting both single-supply and dual-supply configurations. This flexibility allows designers to use it in battery-powered systems at lower voltages while also accommodating industrial designs running from ±7.5 V split supplies, making it a versatile choice across a wide range of applications.
What package does the TLC27L4CD come in and how many op-amps are included?
The TLC27L4CD is housed in a 14-Pin SOIC (Small Outline Integrated Circuit) surface-mount package. It integrates four independent CMOS operational amplifiers in a single package, enabling compact board designs. The SOIC footprint simplifies PCB layout for multi-channel signal conditioning applications such as active filters and sensor interfaces.
What are typical applications for the TLC27L4CD?
Typical applications for the TLC27L4CD include precision instrumentation, active filter design, sample-and-hold circuits, multi-channel data acquisition systems, pH meter front-ends, and photodiode amplifiers. Its ultra-low bias current and CMOS architecture also make it well-suited for portable medical devices, handheld test equipment, and low-power industrial sensors where minimizing power consumption and input loading is critical.
