Fe a t u re s

The MAX1402 low-power, multichannel, serial-output

analog-to-digital converter (ADC) features matched

200µA current sources for sensor excitation. This ADC

uses a sigma-delta modulator with a digital decimation

filter to achieve 16-bit accuracy. The digital filter’s user-

selectable decimation factor allows the conversion res-

olution to be reduced in exchange for a higher output

data rate. True 16-bit performance is achieved at an

output data rate of up to 480sps. In addition, the modu-

lator sampling frequency may be optimized for either

lowest power dissipation or highest throughput rate.

The MAX1402 operates from a +5V supply.

♦ 18-Bit Resolution, Sigma-Delta ADC

♦ 16-Bit Accuracy with No Missing Codes to 480sps

♦ Low Quiescent Current

250µA (operating mode)

2µA (power-down mode)

♦ Matched On-Board Current Sources (200µA) for

Sensor Excitation

♦ 3 Fully Differential or 5 Pseudo-Differential Signal

Input Channels

♦ 2 Additional, Fully Differential Calibration

This device offers three fully differential input channels

that may be independently programmed with a gain

between +1V/V and +128V/V. Furthermore, it can com-

pensate an input-referred DC offset up to 117% of the

selected full-scale range. These three differential chan-

nels may also be configured to operate as five pseudo-

d iffe re ntia l inp ut c ha nne ls . Two a d d itiona l, fully

differential system-calibration channels are provided for

gain and offset error correction.

Channels/Auxiliary Input Channels

♦ Programmable Gain and Offset

♦ Fully Differential Reference Inputs

♦ Converts Continuously or On Command

♦ Automatic Channel Scanning and Continuous

Data Output Mode

♦ Operates with +5V Analog Supply and +3V or +5V

The MAX1402 may be configured to sequentially scan all

signal inputs and provide the results via the serial inter-

face with minimum communications overhead. When

used with a 2.4576MHz or 1.024MHz master clock, the

digital decimation filter can be programmed to produce

zeros in its frequency response at the line frequency and

associated harmonics, ensuring excellent line rejection

without the need for further post-filtering.

Digital Supply

♦ 3-Wire Serial Interface—SPI™/QSPI™ Compatible

♦ 28-Pin SSOP Package
