High-Resolution Analog-to-Digital Converter

FEATURES

DESCRIPTION

•

High Resolution:

The ADS1282 is an extremely high-performance,

single-chip analog-to-digital converter (ADC) with an

integrated, low-noise programmable gain amplifier

(PGA) and two-channel input multiplexer (MUX). The

ADS1282 is suitable for the demanding needs of

130dB SNR (250SPS, High-Resolution Mode)

127dB SNR (250SPS, Low-Power Mode)

•

High Accuracy:

THD: –122dB

INL: 0.5ppm

environments.

•

Low-Noise PGA

The converter uses a fourth-order, inherently stable,

delta-sigma (ΔΣ) modulator that provides outstanding

noise and linearity performance. The modulator is

used either in conjunction with the on-chip digital

filter, or can be bypassed for use with post

processing filters.

Two-Channel Input MUX

Inherently-Stable Modulator with Fast

Responding Over-Range Detection

•

Flexible Digital Filter:

Sinc + FIR + IIR (Selectable)

Linear or Minimum Phase Response

Programmable High-Pass Filter

Selectable FIR Data Rates: 250SPS to 4kSPS

The flexible input MUX provides an additional

external input for measurement, as well as internal

self-test connections. The PGA features outstanding

low noise (5nV/√Hz) and high input impedance,

allowing easy interfacing to geophones and

hydrophones over a wide range of gains.

•

Filter Bypass Option

Low Power Consumption:

High-Resolution Mode: 25mW

Low-Power Mode: 17mW

Shutdown: 10µW

The digital filter provides selectable data rates from

250 to 4000 samples per second (SPS). The

high-pass filter (HPF) features an adjustable corner

frequency. On-chip gain and offset scaling registers

support system calibration.

•

Offset and Gain Calibration Engine

SYNC Input

Analog Supply:

Unipolar (+5V) or Bipolar (±2.5V)

The synchronization input (SYNC) can be used to

synchronize the conversions of multiple ADS1282s.

The SYNC input also accepts a clock input for

continuous alignment of conversions from an external

source.

•

Digital Supply: 1.8V to 3.3V

APPLICATIONS

Two operating modes allow optimization of noise and

power. Together, the amplifier, modulator, and filter

dissipate 25mW and only 17mW in low-power mode.

The ADS1282 is available in a compact TSSOP-28

package and is fully specified from –40°C to +85°C,

with a maximum operating range to +125°C.
