1.5V to 3.6V, 416ksps, 1-Channel True-Differential/

2-Channel Single-Ended, 8-Bit, SAR ADCs

General Description

Features

The MAX1391/MAX1394 micropower, serial-output,

8-bit, analog-to-digital converters (ADCs) operate with a

single power supply from +1.5V to +3.6V. These ADCs

feature automatic shutdown, fast wake-up, and a high-

speed 3-wire interface. Power consumption is only

ꢀ 416ksps, 8-Bit Successive-Approximation

ꢀ Single True-Differential Analog Input Channel

with Unipolar-/Bipolar-Selected Input (MAX1391)

0.743mW (V

= +1.5V) at the maximum conversion

ꢀ Dual Single-Ended Input Channel with Channel-

rate of 416ksps. AutoShutdown™ between conversions

reduces power consumption at slower throughput rates.

Selected Input (MAX1394)

ꢀ ±±0. ꢀSB Iꢁꢀ, ±±0. ꢀSB Dꢁꢀ, ꢁo Missing Codes

ꢀ ±±0.2 ꢀSB Total Unadꢂusted Error (TUE)

ꢀ 49dB SIꢁAD at 1±±kHz Input Frequency

ꢀ Single-Supply Voltage (+102V to +306V)

ꢀ ±097mW at 416ksps, 108V

The MAX1391/MAX1394 require an external reference

REF

that has a wide range from 0.6V to V . The

MAX1391 provides one true-differential analog input

that accepts signals ranging from 0 to V (unipolar

REF

mode) or

vides two single-ended inputs that accept signals rang-

ing from 0 to V . Analog conversion results are

/2 (bipolar mode). The MAX1394 pro-

REF

available through a 5MHz 3-wire SPI™-/QSPI™-/

MICROWIRE™-/digital signal processor (DSP)-compati-

ble serial interface. Excellent dynamic performance,

low voltage, low power, ease of use, and small pack-

age sizes make these converters ideal for portable bat-

tery-powered data-acquisition applications, as well as

other applications that demand low-power consumption

and minimal space.

The MAX1391/MAX1394 are available in a space-sav-

ing (3mm x 3mm), 10-pin TDFN package. The parts

operate over the extended (-40°C to +85°C) and mili-

tary (-55°C to +125°C) temperature ranges.
