The AD7994 is a 4 channel, 12-bit, high speed, low power, successive-approximation ADC. 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 AD7994 provides a two-wire serial interface which is compatible with I^2C interfaces. The part comes in two versions, AD7994-0 and AD7994-1. Each version allows for a minimum of two different I^2C addresses. The I^2C interface on the AD7994-0 supports Standard and Fast I^2C Interface Modes. The I^2C interface on the AD7994-1 supports Standard, Fast and two High-Speed I^2C Interface Modes.
AD7994是一款四通道、12位、高速、低功耗、逐次逼近型ADC。这款器件采用2.7 V 至 5.5 V单电源供电,转换时间为2 us。器件内置四通道多路复用器与跟踪/保持放大器。
AD7994提供双线串行接口,与I^2C接口兼容。这款器件提供AD7994-0与AD7994-1两个版本,每个版本均支持两个不同I^2C地址的最小化。AD7994-0的I^2C接口支持标准与快速I^2C接口模式,而AD7994-1的I^2C接口则支持标准、快速,以及两个高速I^2C接口模式
