Upgrade your microcontroller ADC to true 12-bit performance

Guy Hoover

Abstract

The LTC236x family, which contain 12-bit ADCs that guarantee AC specifications that most built-in microcontroller ADCs cannot meet, is described.

Introduction

Many 8-bit and 16-bit microcontrollers feature 10-bit internal ADCs. A few include 12-bit ADCs, but these often have poor or nonexistent AC specifications, and certainly lack the performance to meet the needs of an increasing number of applications. The LTC2366 and its slower speed versions offer a high performance alternative, as shown in the AC specifications in Table 334.1. Compare these guaranteed specifications with ...
