Description

General part information

AD7492 Series

The AD7492, AD7492-4, and AD7492-5 are 12-bit high speed, low power, successive approximation ADCs. The parts operate from a single 2.7 V to 5.25 V power supply and feature throughput rates up to 1.25 MSPS. They contain a low noise, wide bandwidth track/hold amplifier that can handle bandwidths up to 10 MHz.The conversion process and data acquisition are controlled using standard control inputs allowing for easy interface to microprocessors or DSPs. The input signal is sampled on the falling edge ofCONVSTand conversion is also initiated at this point. The BUSY pin goes high at the start of conversion and goes low 880 ns (AD7492/AD7492-4) or 680 ns (AD7492-5) later to indicate that the conversion is complete. There are no pipeline delays associated with the part. The conversion result is accessed via standardCSandRDsignals over a high speed parallel interface.The AD7492 uses advanced design techniques to achieve very low power dissipation at high throughput rates. With 5 V supplies and 1.25 MSPS, the average current consumption AD7492-5 is typically 2.75 mA. The part also offers flexible power/throughput rate management.It is also possible to operate the part in a full sleep mode and a partial sleep mode, where the part wakes up to do a conversion and automatically enters a sleep mode at the end of conversion. The type of sleep mode is hardware selected by the PS/FSpin.Using these sleep modes allows very low power dissipation numbers at lower throughput rates.The analog input range for the part is 0 V to REFIN. The 2.5 V reference is supplied internally and is available for external referencing. The conversion rate is determined by the internal clock.PRODUCT HGHLIGHTSHigh Throughput with Low Power Consumption. The AD7492-5 offers 1.25 MSPS throughput with 16 mW power consumption.Flexible Power/Throughput Rate Management. The conversion time is determined by an internal clock. The part also features two sleep modes, partial and full, to maximize power efficiency at lower throughput rates.No Pipeline Delay. The part features a standard successive approximation ADC with accurate control of the sampling instant via aCONVSTinput and once-off conversion control.Flexible Digital Interface. The VDRIVEfeature controls the voltage levels on the I/O digital pins.Fewer Peripheral Components. The AD7492 optimizes PCB space by using an internal reference and internal CLK.ol { margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:25px; padding-top:0px; padding-right:0px; padding-bottom:10px; padding-left:0px;} li { padding-top:0px; padding-right:0px; padding-bottom:5px; padding-left:0px; margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px;}
