3.5- and 4.5-Digit, Single-Chip ADCs

with LED Drivers

General Description

Features

The MAX1447/MAX1496/MAX1498 low-power, 3.5- and

4.5-digit, analog-to-digital converters (ADCs) with inte-

grated light-emitting diode (LED) drivers operate from a

single 2.7V to 5.25V power supply. They include an

internal reference, a high-accuracy on-chip oscillator,

and a multiplexed LED display driver. An internal charge

pump generates the negative supply needed to power

the integrated input buffers for single-supply operation.

The ADC is configurable for either a ±2V or ±2±±mV

input range and it outputs its conversion results to an

LED. The MAX1496 is a 3.5-digit (±1999 count) device

and the MAX1447/MAX1498 are 4.5-digit (±19,999

count) devices.

♦ Internal High-Accuracy Oscillator Needs No

The MAX1447/MAX1496/MAX1498 do not require exter-

nal precision integrating capacitors, autozero capaci-

tors, crystal oscillators, charge pumps, or other circuitry

required with dual-slope ADCs (commonly used in

panel meter circuits).

♦ Automatic Offset ꢁalibration

♦ On-Demand Enhanced Offset ꢁalibration

(MAX1447ꢂ

♦ Operate from a Single ±.7ꢃ to 5.±5ꢃ Supply

These devices also feature on-chip buffers for the dif-

ferential signal and reference input, allowing direct

interface with high-impedance signal sources. In addi-

tion, they use continuous internal offset-calibration and

offer >1±±dB rejection of 5±Hz and 6±Hz line noise.

Other features include data hold and peak detection

and overrange/underrange detection. The MAX1447

features on-demand enhanced offset calibration for

improved offset performance.
