Richardson RFPD Inc. announces immediate availability and full design support capabilities for a new 1 MSPS, ultralow power 12-bit successive approximation register analog-to-digital converter (SAR ADC) from Analog Devices Inc. (ADI).

The AD7091 offers ultralow power consumption (typically 367 μA at 3 V and 1 MSPS; 324 μA typical at 3 V in power-down mode) while achieving fast throughput rates (1 MSPS with a 50 MHz SCLK). It operates from a single 2.09 V to 5.25 V power supply and features an on-chip conversion clock and a high speed serial interface. The new device is ideally-suited for applications ranging from battery-powered systems (handheld meters, medical instruments, mobile communications) to instrumentation and control systems, data acquisition systems, optical sensors, diagnostic or monitoring functions, and energy harvesting.

The AD7091 provides high throughput at lowest power, enabling system designers to optimize power budget. Key features include:

  • Scalable power dissipation with throughput:
    • 1.1 mW @ 3V, 1 MSPS
    • 564 μW @ 3V, 500 kSPS
    • 19.6 μW @3V, 5 kSPS
    • <1 μW @3V, power-down
  • INL of +/-1 LSB maximum
  • Flexible interface voltage: 2.09 V to 5.25 V, interfaces to low voltage processors without level shift
  • Space saving 8-lead, 2 mm x 2 mm LFCSP

The AD7091 is part of ADI's Select Products for Q3, 2013. Information about powering a dual supply precision ADC with switching regulators may be found in this application note.
