PARAGON ™ DIGITAL Two Channel DSP System GA3214 PRELIMINARY DATA SHEET DESCRIPTION • highly configurable, versatile DSP platform The GA3214 hybrid is a programmable DSP system based on a two-channel compression circuit. It can be used as a platform for a wide range of hearing aid applications. It’s extensive programmability and compact size make it ideal for sophisticated CIC applications. The reflowable thinSTAX™ packaging enables easy use in BTE applications. This very versatile DSP hybrid is capable of multiple configurations and has a wide range of functions. • high quality two-channel AGC signal processing • fully programmable via serial data interface • high performance data converters - dual, oversampled A/Ds; over-sampled D/A with efficient switched-mode output power amp • drives zero-bias 2-terminal receivers • multiple communication rates up to 85.3kb/s The GA3214 hybrid code programmed into the GC5051 controller chip is “8”. • thinSTAX™ packaging - CIC size • multi-memory This data sheet is a part of a set of documents available for this product. Please refer to “Getting Started with PARAGON™ DIGITAL” information note for a list of other documents. • internal/external volume control • volume control taper determined by external VC • tri-state memory select operation • audible memory change indicator thinSTAX TM PACKAGING Hybrid typical dimensions: 0.227 x 0.125 x 0.060 in (5.76 x 3.18 x 1.52 mm) 7 REG 6 MIC 8 SDA MS VB 4 3 11 12 13n 205n REG VC REGULATOR VC A/D INTERFACE GA3214 EEPROM A/D CHANNEL 1 70n Σ D/A HBRIDGE 13 OUT+ 1 OUT- CHANNEL 2 A/D T 10 60n GND 9 GND 5 2 All resistors in ohms, all capacitors in farads unless otherwise stated.
