2.7V to 3.6V and 4.5V to 5.5V, Low-Power,

4-/12-Channel, 2-Wire Serial 10-Bit ADCs

General Description

Features

o High-Speed I C-Compatible Serial Interface

400kHz Fast Mode

The MAX1136–MAX1139 low-power, 10-bit, multichan-

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

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

1.7MHz High-Speed Mode

I C™-compatible 2-wire serial interface. These devices

o Single-Supply

operate from a single supply of 2.7V to 3.6V (MAX1137/

MAX1139) or 4.5V to 5.5V (MAX1136/MAX1138) 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 MAX1136/MAX1137 have four analog input chan-

nels each, while the MAX1138/MAX1139 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.

2.7V to 3.6V (MAX1137/MAX1139)

4.5V to 5.5V (MAX1136/MAX1138)

o Internal Reference

2.048V (MAX1137/MAX1139)

4.096V (MAX1136/MAX1138)

o External Reference: 1V to V

o Internal Clock

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

Differential (MAX1136/MAX1137)

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

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 MAX1137/

Differential (MAX1138/MAX1139)

o Internal FIFO with Channel-Scan Mode

MAX1139 feature a 2.048V internal reference and the

MAX1136/MAX1138 feature a 4.096V internal reference.

o Low Power

670µA at 94.4ksps

230µA at 40ksps

60µA at 10ksps

6µA at 1ksps

The MAX1136/MAX1137 are available in an 8-pin µMAX

package. The MAX1138/MAX1139 are available in a

16-pin QSOP package. The MAX1136–MAX1139 are

guaranteed over the extended temperature range

(-40°C to +85°C). For pin-compatible 12-bit parts, refer

to the MAX1136–MAX1139 data sheet. For pin-compati-

ble 8-bit parts, refer to the MAX1036–MAX1039 data

sheet.
