AD9221ARSZ

模数转换器 - ADC 12Bit 1.25 MSPS Monolithic

Complete 12-Bit 1.5/3.0/10.0 MSPS  Monolithic A/D Converters

GENERAL DESCRIPTION AD9221ARSZ

The AD9221ARSZ AD9221, AD9223, and AD9220 are a generation of high performance, single supply 12-bit analog-to-digital converters. Each device exhibits true 12-bit linearity and temperature drift performance1 as well as 11.5-bit or better ac performance.2 The AD9221/AD9223/AD9220 share the same interface options, package, and pinout. Thus, the product family provides an upward or downward component selection path based on performance, sample rate and power. The devices differ with respect to their specified sampling rate, and power consumption, which is reflected in their dynamic performance over frequency.
