Overview

The MAX1236–MAX1239 low-power, 12-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 (MAX1237/MAX1239) or 4.5V to 5.5V (MAX1236/MAX1238) 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 MAX1236/MAX1237EUA have four analog input channels each, while the MAX1238/MAX1239 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 VDD. The MAX1237/MAX1239 feature a 2.048V internal reference and the MAX1236/MAX1238 feature a 4.096V internal reference. The MAX1236/MAX1237EUA are available in an 8-pin μMAX package. The MAX1238/MAX1239 are available in a 16-pin QSOP package. The MAX1236–MAX1239 are guaranteed over the extended temperature range (-40°C to +85°C). For pin-compatible 10-bit parts, refer to the MAX1136–MAX1139 data sheet. For pin-compatible 8-bit parts, refer to the MAX1036–MAX1039 data sheet.
