General Description
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 670A at the maximum sampling rate of
94.4ksps. Supply current falls below 230A for sam-
pling rates under 46ksps. AutoShutdown powers
down the devices between conversions, reducing sup-
ply current to less than 1A 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 MAX
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.
