Analog Devices multichannel, 12-bit, 1-MSPS SAR A/D converters allows industrial and medical equipment designers to optimize operating and static power budgets
Analog Devices has introduced 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 4mm x 4mm LFCSP package and feature a 5 ppm/°C typ on-chip internal reference. Watch a video about ADI's new multichannel A/D converters:
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
