19-3051; Rev 0; 10/03

16-Bit, Low-Power, 2-Channel,

Sigma-Delta ADC

General Description

Features

The MX7705 low-power, 2-channel, serial-output ana-

log-to-digital converter (ADC) includes a sigma-delta

modulator with a digital filter to achieve 16-bit resolution

with no missing codes. This ADC is pin compatible and

software compatible with the AD7705. The MX7705 fea-

tures an on-chip input buffer and programmable-gain

amplifier (PGA). The device offers an SPI-/QSPI-/

MICROWIRE-compatible serial interface.

The MX7705 operates from a single 2.7V to 5.25V supply.

The operating supply current is 320µA (typ) with a 3V

supply. Power-down mode reduces the supply current to

2µA (typ).

ꢀ 16-Bit Sigma-Delta ADC

ꢀ Two Fully Differential Input Channels

ꢀ 0.003% Integral Nonlinearity with No Missing Codes

ꢀ Internal Analog Input Buffers

ꢀ PGA from 1 to 128

ꢀ Single (2.7V to 3.6V) or (4.75V to 5.25V) Supply

Self-calibration and system calibration allow the MX7705

to correct for gain and offset errors. Excellent DC perfor-

mance ( 0.003ꢀ ꢁSR IꢂN) and low noise (650nV) maꢃe

the MX7705 ideal for measuring low-frequency signals

with a wide dynamic range. The device accepts fully dif-

ferential bipolar/unipolar inputs. An internal input buffer

allows for input signals with high source impedances. An

on-chip digital filter, with a programmable cutoff and out-

put data rate, processes the output of the sigma-delta

modulator. The first notch frequency of the digital filter is

chosen to provide 150dB rejection of common-mode

50Hz or 60Hz noise and 98dB rejection of normal-mode

50Hz or 60Hz noise. A PGA and digital filtering allow sig-

nals to be directly acquired with little or no signal-condi-

tioning requirements.
