250ksps, +3V, 8-/4-Channel, 10-Bit ADCs

with +2.5V Reference and Parallel Interface

General Description

Features

The MAX1091/MAX1093 low-power, 10-bit analog-to-

digital converters (ADCs) feature a successive-approxi-

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

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

high-speed, byte-wide parallel interface. They operate

ꢀ 10-Bit Resolution, ±0.5LSB Linearity

ꢀ User-Adjustable Logic Level (+1.8V to +3.6V)

ꢀ Internal +2.5V Reference

pin that allows them to interface directly with a +1.8V to

+3.6V digital supply.

the maximum sampling rate of 250ksps. Two software-

selectable power-down modes enable the MAX1091/

MAX1093 to be shut down between conversions;

accessing the parallel 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 MAX1091 has

eight input channels and the MAX1093 has four input

channels (four and two input channels, respectively,

when in pseudo-differential mode).

ꢀ Internal 3MHz Full-Power Bandwidth Track/Hold

ꢀ Byte-Wide Parallel (8+2) Interface

ꢀ Small Footprint: 28-Pin QSOP (MAX1091)

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 demand-

ing power consumption and space requirements.

24-Pin QSOP (MAX1093)

Pin Configurations

The MAX1091 is available in a 28-pin QSOP package,

while the MAX1093 is available in a 24-pin QSOP. For

pin-compatible +5V, 10-bit versions, refer to the

MAX1090/MAX1092 data sheet.
