I.C

AD7490 is a 12-bit high speed, low power, 16-channel, successive approximation ADC. The part contains a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 1MHz. The conversion process and data acquisition are controlled using CS and the serial clock signal, allowing the device to easily interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS, and conversion is also initiated at this point. There are no pipeline delays associated with the part. It is widely used in application such as multichannel system monitoring, battery-powered equipment, power line monitoring, data acquisition, instrumentation, and process control etc.
