Introduction

Until now, high speed system designers had to compromise when selecting 1Msps 12-bit A/D converters. While hybrids typically had the best performance, they were big, power hungry (∼1W) and costly (>$100). A few manufacturers offered monolithics, but they compromised either AC or DC performance.

That has now changed. The new LTC1410 monolithic 1.25Msps 12-bit ADC performs better than hybrids with the power dissipation, size and cost of monolithics.
