Multichannel, 12-bit, 1-MSPS SAR A/D converters allows industrial and medical equipment designers to optimize operating and static power budgets.

Bangalore, India, Aug 28, 2014: -  Analog Devices, Inc. (ADI) introduced today three ultra-low-power, multichannel, 12-bit, 1-MSPS SAR (successive approximation register)  A/D converters. The new 2, 4 and 8-channel A/D converters are designed for battery-powered data acquisition modules, handheld meters, field instruments and communications applications as well as medical devices such as portable electrocardiograms and heart rate monitors. The A/D converters are the most power-efficient in their class, dissipating a maximum of 1.7 mW at 1 MSPS (mega-samples per second), which is over 60 percent less power than the closest SAR A/D converter competitor. The A/D converters are housed in a tiny 4-mm × 4-mm LFCSP package and feature a 5 ppm/°C typ on-chip internal reference.

Key Features-

• 1 MSPS throughput with flexible power/throughput rate management
• Power consumption at 3V supply:
  - 1.7 mW @ 1 MSPS
  - 900 µW @ 500 kSPS
  - 1.4 µW @ powerdown
• Programmable channel sequencer with access to the multiplexer output eliminates the need for one buffer per channel saving both power and space
• User programmable alert can signal an out-of-bounds condition without requiring the user to service the A/D converter output data (minimizes processor overhead/power)
• SPI interface
• Temperature range: –40°C to +125°C
