INTRODUCTION

INTRODUCTION The KA9257, a monolithic integrated circuit, is a dual power operational amplifier with a maxmum output current of 0.5A. FEATURESFEATURES • 2 channel BTL driver • Low input bias (lib=30nA) • Built in phase compensation capacitor • Housed in a 12SIP H/S package for easy heat disc

PLL FOR DTS

DESCRIPTION The SC9257 is phase-locked loop (PLL) LSIs for digital tuning systems (DTS) with built in 2 modulus prescalers. All functions ate controlled through 3 serial bus lines. These LSIs are used to configure high-performance digital tuning system. FEATURES * Optimal for configurin
