GENERAL DESCRIPTION
The AD7993/AD7994 are 4-channel, 10- and 12-bit, low power, successive approximation ADCs with an I2C-compatible interface. The parts operate from a single 2.7 V to 5.5 V power supply and feature a 2 µs conversion time. The parts contain a 4-channel multiplexer and track-and-hold amplifier that can handle input frequencies up to 11 MHz.
