The AD7912 / AD7922 are 10-bit and 12-bit, high speed, low power, 2-channel, successive-approximation ADCs respectively. The parts operate from a single 2.35 V to 5.25 V power supply and feature through put rates up to 1 MSPS. The parts contain a low-noise, wide bandwidth track/hold amplifier, which can handle input frequencies in excess of 6 MHz.The conversion process and data acquisition are controlled using CS and the serial clock, allowing the devices to interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS and the conversion is also initiated at this point. There are no pipeline delays associated with the part. The channel to be converted is selected through the DIN pin and the mode of operation is controlled by CS. The serial data stream from the DOUT pin has a channel identifier bit and a mode identifier bit, which provide information about the channel converted and the current mode of operation.As a result of the Daisy Chain mode of operation, several AD7912 / AD7922 can be connected together in Daisy Chain configuration. The Daisy Chain mode allows the user to read the conversion result from the ADCs contained in the chain.Several AD7912 / AD7922 can be connected together in a daisychain. The AD7912 / AD7922 feature a daisy-chain mode thatallows the user to read the conversion results from the ADCscontained in the chain. The AD7912/AD7922 use advanceddesign techniques to achieve very low power dissipation at highthroughput rates. The reference for the part is taken internallyfrom VDD, thereby allowing the widest dynamic input range tothe ADC. PRODUCT HIGHLIGHTS 2-channel, 1 MSPS, 10-/12-bit ADCs in TSOT package. High throughput with low power consumption. Flexible power/serial clock speed management. The conversion rate is determined by the serial clock. The parts also feature a power-down mode to maximize power efficiency at lower throughput rates. Average power consumption is reduced when the power-down mode is used while not converting. Current consumption is 1 µA maximum and 50 nA typically when in power-down mode. Daisy-chain mode. No pipeline delay. The parts feature a standard successive approximation ADC with accurate control of the sampling instant via a CS input and once-off conversion control.
