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, multichan-

nel analog-to-digital converters (ADCs) feature internal

track/hold (T/H), voltage reference, clock, and an

Features

♦ High-Speed I C-Compatible Serial Interface

400kHz Fast Mode

1.7MHz High-Speed Mode

♦ Single-Supply

I C-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.

4.5V to 5.5V (MAX1236/MAX1238)

♦ Internal Reference

2.048V (MAX1237/MAX1239)

4.096V (MAX1236/MAX1238)

♦ External Reference: 1V to V

♦ Internal Clock

♦ 4-Channel Single-Ended or 2-Channel Fully

Differential (MAX1236/MAX1237)

♦ 12-Channel Single-Ended or 6-Channel Fully

Differential (MAX1238/MAX1239)

♦ Internal FIFO with Channel-Scan Mode

♦ Low Power

The full-scale analog input range is determined by the

internal reference or by an externally applied reference

voltage ranging from 1V to V . The MAX1237/

670µA at 94.4ksps

230µA at 40ksps

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.
