MAX1160x Converters

Maxim Integrated's MAX11600, 11601, 11602, 11603, 11604, and 11605 low-power, 8-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 and require only 350 µA at the maximum sampling rate of 188 ksps. AutoShutdown™ powers down the devices between conversions, reducing supply current to less than 1µA at low throughput rates. The MAX11600/MAX11601 provide 4 analog input channels each, the MAX11602/MAX11603 provide 8 analog input channels each, and the MAX11604/MAX11605 each provide 12 analog input channels. The analog inputs are software-configurable for unipolar or bipolar and single-ended or pseudo-differential operation.

The full-scale analog input range is determined by the internal reference or by an externally applied reference voltage ranging from 1 V to VDD. The MAX11601/MAX11603/MAX11605 all feature a 2.048 V internal reference, while the MAX11600/MAX11602/MAX11604 feature a 4.096 V internal reference.

The MAX11600/MAX11601 are both available in 8-pin SOT23 packages. The MAX11602 through MAX11605 are available in 16-pin QSOP packages. Each converter is guaranteed over the extended industrial temperature range (-40°C to +85°C).
