Features & Applications
Austriamicrosystems designs, manufactures and markets high performance analog integrated circuits for communications, industrial, medical and automotive markets building on more than 25 years of analog design capabilities, system know-how, and own state-of-the-art manufacturing and test facilities.
Austriamicrosystems’ focuses on power management, sensors & sensor interfaces, portable audio and car access applications, and offers the industry's broadest range of high performance absolute and incremental rotary and linear magnetic encoder devices that are complete SoC solutions integrating Hall element, analog front end and digital signal processing.
The AS253x is a very flexible CMOS integrated circuit family that contains all the functions needed to build a high performance electronic telephone set with basic features.
The AS253x incorporates a line interface, a speech circuit, a dialler and ringer. It is a real single-chip / single-die IC with 28 pins. It allows either package mounting or chip-onboard mounting.
The device is available in 4 versions (pin-compatible) with different features ranging from LNR only (last number redial) to 4 direct (one-touch) memories and 10 indirect (two-touch) memories. The sliding cursor procedure makes the LNR function easy to use under various PABX systems.
The versatility of the circuit is provided by pin options and a few external components. This allows fast time-to-market and easy adaptation to different PTT requirements. A unique EMI performance has been achieved due to the consequent use of CMOS amplifiers.
The AS2533TR is a Multi-Standard CMOS Telephone IC for Basic Telephones with LNR, 4 direct/10 indirect memories, available in a 28-pin plastic SOIC package.
