Wide-band IR sensor from Vishay

Vishay Intertechnology Inc. has released a device that implements a wide-band IR sensor for code learning and IR extender applications.

The TSOP98200 has been developed to address the growing need for an AC-coupled IR sensor covering the entire remote control bandwidth of 30kHz to 455kHz. The new device features a photo diode and a wide-band amplifier mounted within a 3-pin epoxy-encapsulated module with an integrated semi-cylindrical lens.

In contrast to many available IR sensors, the new device is AC coupled to prevent activating the sensor from constant light sources such as tungsten bulbs or sunlight. This feature provides optimal reception of the IR code even in the presence of these light sources.

The new IR sensor is specified for operation with supply voltages from 2.7V to 5.5V, while the TTL- and CMOS-compatible output can be directly connected to digital circuitry such as a microprocessor. The small package simplifies the design and layout of compact IR extender and code learning systems.

Samples and production quantities of the new TSOP98200 IR sensors are available today, with lead times of 10 weeks for large orders.
