TSH511

TSH511 HiFi stereo/mono infrared receiver Stereo sub-carrier demodulator s s s s s s s s Supply voltage: 2.3V to 5.5V Carriers frequency range: 0.4 to 11 MHz Two FM receivers for stereo Integrated audio buffers Audio outputs: 20 mW into 16 ohms High sensitivity: 4µV @12dB SINAD Flexibility: access pins for each section Receiver 2 Standby for mono operation PACKAGE DESCRIPTION The TSH511 is a 0.4 to 11 MHz dual FM receiver. This circuit offers the functions needed for a highly sensitive infrared HiFi STEREO receiver. Featuring high input sensitivity and high input dynamic range, each receiver integrates a RF front-end LNA, an intermediate amplifier with 2 external filters, a voltage limiter, a quadrature FM demodulator, and finally an audio buffer. The integrated audio buffers are able to drive directly a 16 ohms headphone with 20mW. A SQUELCH circuit mutes both audio amplifiers. Access pins to each section makes the TSH511 suited for a wide field of applications. For MONO applications, the STANDBY pin enables one receiver only, reducing the supply current. The TSH511 forms a chipset with the dual transmitter TSH512.
