Description

ADC SERIAL 12BIT 4/12-CH 1239
The MAX1236–MAX1239 low-power, 12-bit, multichan- nel 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 sam- pling rates under 46ksps. AutoShutdown™ powers down the devices between conversions, reducing sup- ply current to less than 1µA at low throughput rates. The MAX1236/MAX1237 have four analog input chan- nels each, while the MAX1238/MAX1239 have 12 ana- log 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/MAX1237 are available in an 8-pin µMAX® package. The MAX1238/MAX1239 are available in a 16- pin QSOP package. The MAX1236–MAX1239 are guar- anteed 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.
