The AD7091R-2/AD7091R-4/AD7091R-8 family is a multichannel12-bit, ultralow power, successive approximation analog-to-digitalconverter (ADC) that is available in two, four, or eightanalog input channel options. The AD7091R-2/AD7091R-4/AD7091R-8 operate from a single 2.7 V to 5.25 V power supplyand are capable of achieving a sampling rate of 1 MSPS.
The AD7091R-2/AD7091R-4/AD7091R-8 family offers up to eightsingle-ended analog input channels with a channel sequencerthat allows a preprogrammed selection of channels to be convertedsequentially. The AD7091R-2/AD7091R-4/ AD7091R-8 alsofeature an on-chip conversion clock, an on-chip accurate 2.5 Vreference, and a high speed serial interface.
The AD7091R-2/AD7091R-4/AD7091R-8 have a serial portinterface (SPI) that allows data to be read after the conversionwhile achieving a 1 MSPS throughput rate. The conversion processand data acquisition are controlled using the CONVST pin.
The AD7091R-2/AD7091R-4/AD7091R-8 use advanced designtechniques to achieve ultralow power dissipation at highthroughput rates. They also feature flexible power managementoptions. An on-chip configuration register allows the user to set updifferent operating conditions. These include power management,alert functionality, busy indication, channel sequencing, andgeneral-purpose output pins. The MUXOUT and ADCIN pinsallow signal conditioning of the multiplexer output prior toacquisition by the ADC.
