AD7091R-8 8-Channel, 1 MSPS, Ultralow Power, 12-Bit ADC in 24-Lead TSSOP
The AD7091R-2/AD7091R-4/AD7091R-8 family is a multichannel
12-bit, ultralow power, successive approximation analog-to-digital
converter (ADC) that is available in two, four, or eight
analog input channel options. The AD7091R-2/AD7091R-4/
AD7091R-8 operate from a single 2.7 V to 5.25 V power supply
and are capable of achieving a sampling rate of 1 MSPS.
The AD7091R-2/AD7091R-4/AD7091R-8 family offers up to eight
single-ended analog input channels with a channel sequencer
that allows a preprogrammed selection of channels to be converted
sequentially. The AD7091R-2/AD7091R-4/ AD7091R-8 also
feature an on-chip conversion clock, an on-chip accurate 2.5 V
reference, and a high speed serial interface.
The AD7091R-2/AD7091R-4/AD7091R-8 have a serial port
interface (SPI) that allows data to be read after the conversion
while achieving a 1 MSPS throughput rate. The conversion process
and data acquisition are controlled using the CONVST pin.
The AD7091R-2/AD7091R-4/AD7091R-8 use advanced design
techniques to achieve ultralow power dissipation at high
throughput rates. They also feature flexible power management
options. An on-chip configuration register allows the user to set up
different operating conditions. These include power management,
alert functionality, busy indication, channel sequencing, and
general-purpose output pins. The MUXOUT and ADCIN pins
allow signal conditioning of the multiplexer output prior to
acquisition by the ADC.
