MAX1416EWE 数据手册

19-3163; Rev 1; 12/05

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

Sigma-Delta ADCs

General Description

Features

The MAX1415/MAX1416 low-power, 2-channel, serial-

output analog-to-digital converters (ADCs) use a sigma-

delta modulator with a digital filter to achieve 16-bit

resolution with no missing codes. These ADCs are pin-

compatible upgrades to the MX7705/AD7705. The

MAX1415/MAX1416 feature an internal oscillator (1MHz

or 2.4576MHz), an on-chip input buffer, and a program-

mable gain amplifier (PGA). The devices offer an SPI™-/

QSPI™-/MICROWIRE™-compatible serial interface.

♦ 16-Bit Sigma-Delta ADCs

♦ Two Fully Differential Input Channels

♦ 0.0015% Integral Nonlinearity with No Missing

Codes

♦ Internal Analog Input Buffers

♦ Programmable Gain Amplifier (PGA) from 1 to 128

♦ Internal Oscillator (2.4576MHz or 1MHz)

♦ Single 2.7V to 3.6V (MAX1415) or 4.75V to 5.25V

The MAX1415 requires a single 2.7V to 3.6V supply, and

the MAX1416 requires a single 4.75V to 5.25V supply.

The operating supply current is 400µA (max) with a 3V

supply. Power-down mode reduces the supply current to

2µA (typ). When operating with a supply of 3V, the power

dissipation is less than 1.44mW, making the MAX1415

ideal for battery-powered applications.

(MAX1416) Supply

♦ Low Power

1mW max, 3V Supply

2µA (typ) Power-Down Current

♦ SPI™-/QSPI™-/MICROWIRE™-Compatible 3-Wire

Serial Interface

Self-calibration and system calibration allow the

MAX1415/MAX1416 to correct for gain and offset errors.

Excellent DC performance ( 0.0015ꢀ ꢁSR IꢂN) and low

noise (700nV in unbuffered mode) make the MAX1415/

MAX1416 ideal for measuring low-frequency signals with

a wide dynamic range. These devices accept fully differ-

ential 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.

♦ Pin Compatible with MX7705/AD7705

♦ 16-Pin PDIP, SO, and TSSOP Packages
