AD7291BCPZ-RL7(RevPrC) Datasheet PDF - Analog Devices

GENERAL DESCRIPTION
The AD7291 is a 12-bit, high speed, low power, 8-channel, successive approximation ADC with an internal temperature sensor. The part operates from a single 3.3V power supply and features an I2C®-compatible interface. The track-and-hold amplifier which can handle input frequencies of up to 70MHz, and a multiplexer allows samples from eight channels.
