Product Details
●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 µs. The part contains a four channel multiplexer and track/hold amplifier.
●The AD7994 provides a two-wire serial interface which is compatible with I2C interfaces. The part comes in two versions, AD7994-0 and AD7994-1. Each version allows for a minimum of two different I2C addresses. The I2C interface on the AD7994-0 supports Standard and Fast I2C Interface Modes. The I2C interface on the AD7994-1 supports Standard, Fast and two High-Speed I2C Interface Modes.
