Fe a t u re s

The MAX1400 18-bit, low-power, multichannel, serial-

output ADC uses a sigma-delta modulator with a digital

decimation filter to achieve true 16-bit accuracy. The

user-selectable decimation factor of the digital filter

a llows the c onve rs ion re s olution to b e re d uc e d in

exchange for a higher output data rate. The device

achieves true 16-bit performance at an output data rate of

up to 480s p s . In a d d ition, the mod ula tor s a mp ling

frequency may be optimized for either lowest power

dissipation or highest throughput rate. The MAX1400

operates from +5V.

♦ 18-Bit Resolution, Sigma-Delta ADC

♦ 16-Bit Performance with No Missing Codes

to 480sps

♦ Low Quiescent Current

250µA (operating mode)

2µA (power-down mode)

♦ 3 Fully Differential or 5 Pseudo-Differential Signal

Input Channels

♦ 2 Additional Fully Differential Calibration

This device offers three fully differential input channels

that can be independently programmed with a gain

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

pensate an input-referred DC offset (such as system off-

set) up to 117% of the selected full-scale range. These

three differential channels may also be configured to

operate as five pseudo-differential input channels. Two

additional, fully differential system-calibration channels

are provided for gain and offset error correction. External

access is provided to the multiplexer (mux) output to

facilitate additional signal processing.

Channels/Auxiliary Input Channels

♦ Access to the Mux Output/ADC Input

♦ 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 Digital Supply

The MAX1400 can be configured to scan all signal inputs

sequentially and provide the results through the serial

interface with minimum communications overhead. When

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

digital decimation filter can be programmed to produce

ze ros in its fre q ue nc y re s p ons e a t the line fre -

quency and associated harmonics, ensuring excellent

line rejection without the need for further post-filtering.

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

♦ 28-Pin SSOP Package
