Linear Technology LTC202CN Dual SPST JFET Switch

The LTC202CN is a high-performance, dual single-pole single-throw (SPST) JFET switch designed and manufactured by Linear Technology, a company renowned for its precision electronic components. This switch is engineered to offer a combination of low on-resistance and low charge injection, making it an excellent choice for a variety of applications including data acquisition systems, sample-and-hold circuits, and communication systems.

The LTC202CN operates over a wide supply voltage range of ±15V, which allows for a broad range of signal handling capabilities. The switch's JFET technology ensures that the on-resistance is typically only 300 ohms, which remains constant over the full analog signal range. This feature is critical for applications that require low distortion and high linearity.

One of the key advantages of the LTC202CN is its low charge injection, which is typically just 5 pC. This makes the switch particularly suitable for precision applications where maintaining signal integrity is of utmost importance. Additionally, the switch exhibits an off-leakage current of only 20pA at 25°C, which minimizes the effect on the circuits when the switch is in the off state.

The LTC202CN also boasts a fast switching speed, with turn-on and turn-off times of approximately 175ns and 145ns, respectively. This rapid switching capability is beneficial for applications that require high-speed operation without sacrificing performance.

For design flexibility, the LTC202CN features a plug-in compatible pinout, which allows for easy integration into existing designs without the need for significant board changes. Its dual SPST configuration means that two independent switches are contained within a single package, providing a compact solution for applications with limited space.

Overall, the LTC202CN from Linear Technology is a versatile and reliable switch that offers consistent performance across a range of conditions. Its low on-resistance, low charge injection, and fast switching speeds make it an ideal choice for designers seeking a high-quality switch for their precision electronic applications.
