Next-Generation Miniature IR Receivers Provide Improved Sensitivity, Noise Suppression, and Pulse-Width Accuracy

For Remote Control Applications, New Devices Offer Increased Robustness to Optical and RF Emissions Without Sacrificing Sensitivity.

Product Benefits:

• Feature a photodetector, preamplifier circuit, and IR filter in a single 3-pin epoxy package

• Offered in Cast, Mold, Minimold, and Minicast packages

• Available with carrier frequencies from 30 kHz to 56 kHz

• Six automatic gain control (AGC) versions for short and long burst codes

• Feature a supply voltage from 2.5 V to 5.5 V

• Low supply current

• RoHS-compliant, halogen-free, and Vishay Green

Market Applications:

• Infrared (IR) remote control in televisions, set-top boxes (STBs), audio systems, air conditioners, video projectors, cameras, and video game systems

The News:

Vishay Intertechnology introduces the next generation of the company’s miniature IR receiver modules for IR remote control applications. Devices in the Vishay Semiconductors TSOP11xxx, TSOP12xxx, TSOP13xxx, TSOP14xxx, and TSOP18xxx families deliver both improved dark-ambient and disturbed-ambient sensitivity to infrared signals, as well as better suppression of RF noise.

• Provide increased robustness against disturbances such as IR emissions from CFL lamps and RF emissions from on-board Wi-Fi antennas

• Improved pulse-width accuracy for lower bit error rates

• Suitable for codes demanding even the tightest pulse-width specifications, such as SIRCS and RCMM

• Insensitive to supply voltage variations and ripple noise

• Simplify designs

The Key Specifications:

Carrier frequencies: 30 kHz to 56 kHz
