Analog Devices internal reference mounted A/D converter,

Low power consumption and high accuracy implemented in a small package

– The use of multi-channel, 12-bit, 1MSPS SAR A/D converters enables industrial and medical equipment designers to optimize operating and static power consumption.

August 28, 2014 – Analog Devices (www.analog.com, NASDAQ: ADI), a global leader in high-performance semiconductors for signal processing applications, has launched three ultra-low-power, multi-channel, 12-bit, 1MSPS successive approximation register (SAR) A/D converters. The newly released 2-, 4-, and 8-channel A/D converters are suitable for medical equipment, such as portable ECG and heart rate monitors, as well as battery-powered data acquisition modules, portable instruments, and field measurement and communications applications. These A/D converters feature the best power consumption efficiency in their class, with power consumption at 1MSPS (mega-samples per second) reaching a maximum of only 1.7mW, which is 60% lower than comparable SAR A/D converter products. The A/D converters are available in a small 4mm × 4mm LFCSP package and boast an average value of 5 ppm/°C at the on-chip internal reference. You can watch a video about ADI's newly released multi-channel A/D converter here.

Key Performance:

• 1MSPS throughput with flexible power/throughput rate management

• Power consumption when supplied at 3V:

o 1.7mW at 1MSPS

o 900μW at 500kSPS

o 1.4μW in powerdown

• A channel sequencer that can access the multiplexer output can be programmed, eliminating the need for a buffer for each channel and saving both power and space.

• The user can program the warning signal, so that if the condition exceeds the limit (out-of-bounds condition), it warns without providing output data to the A/D converter. Signal generation possible (minimizing processor overhead/power)

• SPI interface

• Temperature range: –40°C to +125°C
