400ksps, +5V, 8-/4-Channel, 10-Bit ADCs

with +2.5V Reference and Parallel Interface

General Description

Features

The MAX1090/MAX1092 low-power, 10-bit analog-to-

digital converters (ADCs) feature a successive-approxi-

mation ADC, automatic power-down, fast wake-up

(2µs), on-chip clock, +2.5V internal reference, and

high-speed, byte-wide parallel interface. The devices

operate with a single +5V analog supply and feature a

4-Chꢁnnel Pseudo-Diffeaentiꢁl (MAX1090)

400ksps max sampling rate. Two software-selectable

power-down modes enable the MAX1090/MAX1092 to

be shut down between conversions; accessing the par-

allel interface returns them to normal operation.

Powering down between conversions can cut supply

current to under 10µA at reduced sampling rates.

Both devices offer software-configurable analog inputs

for unipolar/bipolar and single-ended/pseudo-differen-

tial operation. In single-ended mode, the MAX1090 has

eight input channels and the MAX1092 has four input

channels (four and two input channels, respectively,

when in pseudo-differential mode).

Excellent dynamic performance and low power com-

bined with ease of use and small package size make

these converters ideal for battery-powered and data-

acquisition applications or for other circuits with

demanding power consumption and space require-

ments.

Pin Configurations

The MAX1090 is available in a 28-pin QSOP package,

while the MAX1092 comes in a 24-pin QSOP. For pin-

compatible +3V, 10-bit versions, refer to the MAX1091/

MAX1093 data sheet.
