Overview
19-2333; Rev 7; 5/10 MAX1236–MAX1239 2.
7V to 3.
6V and 4.
5V to 5.
5V, Low-Power, 4-/12-Channel, 2-Wire Serial, 12-Bit ADCs General Description 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/MAX1237 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 det...
