The AD7470/AD7472 are 10-bit/12-bit high speed, low power, AD7472 IS A 12-BIT PART WITH DB0 TO DB11 AS OUTPUTS. successive approximation ADCs. The parts operate from a single2.7 V to 5.25 V power supply and feature throughput rates up to1.5 MSPS for the 12-bit AD7472 and up to 1.75 MSPS for the It is also possible to operate the parts in an auto sleep mode, 10-bit AD7470. The parts contain a low noise, wide bandwidth where the part wakes up to do a conversion and automatically track-and-hold amplifier that can handle input frequencies in enters sleep mode at the end of conversion. This method allows excess of 1 MHz. very low power dissipation numbers at lower throughput rates.In this mode, the AD7472 can be operated with 3 V supplies at The conversion process and data acquisition are controlled
