The MAX132 is a CMOS, 18-bit plus sign, serial-output,

analog-to-digital converter (ADC). Multi-slope integra-

tion provides high-resolution conversions in less time

than standard integrating ADCs, allowing operation up

to 100 conversions per second. Low conversion noise

provides guaranteed operation with ±512mV full-scale

input range (2µV/LSB). A simple 4-wire serial interface

connects easily to all common microprocessors, and

twos-complement output coding simplifies bipolar mea-

surements. Typical supply current is only 60µA and is

re d uc e d to 1µA in s le e p mod e . Four s e ria lly p ro-

grammed digital outputs can be used to control an

external multiplexer or programmable-gain amplifier.

The MAX132 comes in 24-pin narrow DIP and wide SO

packages, and is available in commercial and extend-

ed temperature grades.

♦ Low Supply Current:

60µA (Normal Operation)

1µA (Sleep-Mode Operation)

♦ ±0.006% FSR Accuracy at 16 Conv/sec

♦ Low Noise: 15µV

RMS

♦ Serial I/O Interface with Programmed Output for

Mux and PGA

♦ Performs up to 100 Conv/sec

♦ ±2pA Input Current

♦ 50Hz/60Hz Rejection

______________Ord e rin g In fo rm a t io n

High resolution, compact size, and low power make this

device ideal for data loggers, weigh scales, data-acqui-

sition systems, and panel meters.
