AD7091R-2 2-Channel, 1 MSPS, Ultralow Power, 12-Bit ADC in 16-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.
