MAX11608

19-4560; Rev 0; 4/09 www.DataSheet4U.com 2.7V to 3.6V and 4.5V to 5.5V, Low-Power, 4-/8-/12-Channel, 2-Wire Serial 10-Bit ADCs General Description The MAX11606–MAX11611 low-power, 10-bit, multichannel analog-to-digital converters (ADCs) feature internal track/hold (T/H), voltage reference, clock, and an I2C-compatible 2-wire serial interface. These devices operate from a single supply of 2.7V to 3.6V (MAX11607/ MAX11609/MAX11611) or 4.5V to 5.5V (MAX11606/ MAX11608/MAX11610) and require only 670µA at the maximum sampling rate of 94.4ksps. Supply current falls below 230µA for sampling rates under 46ksps. AutoShutdown™ powers down the devices between conversions, reducing supply current to less than 1µA at low throughput rates. The MAX11606/MAX11607 have 4 analog input channels each, the MAX11608/MAX11609 have 8 analog input channels each, while the MAX11610/MAX11611 have 12 analog input channels each. The fully differential analog inputs are software configurable for unipolar or bipolar, and single ended or differential operation. The full-scale analog input range is determined by the internal reference or by an externally applied reference voltage ranging from 1V to V DD . The MAX11607/ MAX11609/MAX11611 feature a 2.048V internal reference and the MAX11606/MAX11608/MAX11610 feature a 4.096V internal reference. The MAX11606/MAX11607 are available in an 8-pin µMAX® package. The MAX11608–MAX11611 are available in a 16-pin QSOP package. The MAX11606– MAX11611 are guaranteed ove...
