256K Nonvolatille SRAM

DESCRIPTION The DS1235Y/AB 256K Nonvolatile SRAM is a 262,144-bit, fully static SRAM organized as 32,768 words by 8 bits. The nonvolatile memory has a self-contained lithium energy source and control circuitry that constantly monitor VCC for an out-of-tolerance condition. When such a condition oc

FM IF System Applications

Overview The LA1235 is a high integrated IC developed for use in high S/N, low distortion FM IF system applications. This IC features S/N=88dB, distortion factor=0.015 and has almost all functions required for FM tuner IF stage. Features • High S/N (88dB typ.). • Low distortion (0.01
