SMD IR Receivers Integrate Two Photodiodes + EMI Shielding

The TSOP75xxxW surface-mount infrared receivers emerge as the industry's first such devices to feature two photodiodes along with patented internal metal EMI shielding inside a package with a 2.35-mm profile. The lens-less design of the devices reportedly results in the industry's best sensitivity-to-size ratio with irradiance from 0.3 mW/sqm to 0.7 mW/sqm over an angle of ± 75°. The devices are available in three automatic-gain-control versions, all of which specify a power consumption of 0.35 mA typical at 3.3V. Other features include a supply voltage range of 2.5V to 5.5V and a carrier frequency of 30 kHz to 56 kHz. Pricing begins at $1 each. VISHAY INTERTECHNOLOGY, INC., Malvern, PA. (619) 336-0860.
