AD7997 8-Channel, 10-Bit ADC with I2C Compatible Interface in 20-Lead TSSOP
The AD7997 is an 8 channel, 10-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 an eight channel multiplexer and track/hold amplifier.
The AD7997 provides a two-wire serial interface, which is compatible with I2C interfaces. The part come in two versions, AD7997-0 and AD7997-1. Each version allows for a minimum of two different I2C addresses. The I2C interface on the AD7997-0 supports Standard and Fast I2C Interface Modes. The I2C Interface on the AD7997-1 supports Standard, Fast and two High-Speed I2C Interface Modes.
