The AD7993 is a 4 channel, 10-bit, high speed, low power, successive-approximation ADC respectively. The part operates from a single 2.7 V to 5.5 V power supply and features a conversion time of 2 us. The part contains a four channel multiplexer and track/hold amplifier.
The AD7993 provides a two-wire serial interface which is compatible with I^2C interfaces. The part comes in two versions, AD7993-0 and AD7993-1. Each version allows for a minimum of two different I^2C addresses. The I^2C interface on the AD7993-0 supports Standard and Fast I^2C Interface Modes. The I^2C interface on the AD7993-1 supports Standard, Fast and two High-Speed I^2C Interface Modes.
AD7993是一款4通道、10位、高速、低功耗、逐次逼近型ADC,采用2.7 V至5.5 V单电源供电,转换时间为2 微秒（us）。该器件内置4通道多路复用器和采样保持放大器。
AD7993提供与I^2C接口兼容的双线式串行接口。该器件有两个版本：AD7993-0和AD7993-1,每个版本允许最少使用两个不同的I^2C地址。AD7993-0上的I^2C接口支持标准和快速I^2C两种接口模式。AD7993-1上的I^2C接口支持标准、快速及两种高速I^2C接口模式
