24-Bit

ANALOG-TO-DIGITAL CONVERTER

DESCRIPTION

FEATURES

● 24 BITS NO MISSING CODES

The ADS1240 and ADS1241 are precision, wide dynamic range,

delta-sigma, Analog-to-Digital (A/D) converters with 24-bit resolution

operating from 2.7V to 5.25V power supplies. The delta-sigma A/D

converter provides up to 24 bits of no missing code performance and

effective resolution of 21 bits.

● SIMULTANEOUS 50Hz AND 60Hz REJECTION

(–90dB MINIMUM)

● 0.0015% INL

● 21 BITS EFFECTIVE RESOLUTION

The input channels are multiplexed. Internal buffering can be

selected to provide very high input impedance for direct connection

to transducers or low-level voltage signals. Burnout current sources

are provided that allow for detection of an open or shorted sensor.

An 8-bit Digital-to-Analog (D/A) converter provides an offset cor-

rection with a range of 50% of the Full-Scale Range (FSR).

(PGA = 1), 19 BITS (PGA = 128)

● PGA GAINS FROM 1 TO 128

● SINGLE CYCLE SETTLING

● PROGRAMMABLE DATA OUTPUT RATES

● EXTERNAL DIFFERENTIAL REFERENCE

OF 0.1V TO 5V

The Programmable Gain Amplifier (PGA) provides selectable gains of

1 to 128, with an effective resolution of 19 bits at a gain of 128. The

A/D conversion is accomplished with a 2nd-order delta-sigma modu-

lator and programmable Finite-Impulse Response (FIR) filter that

provides a simultaneous 50Hz and 60Hz notch. The reference input

is differential and can be used for ratiometric conversion.

● ON-CHIP CALIBRATION

● SPI™ COMPATIBLE

● 2.7V TO 5.25V SUPPLY RANGE

● 600µW POWER CONSUMPTION

● UP TO EIGHT INPUT CHANNELS

● UP TO EIGHT DATA I/O

The serial interface is SPI compatible. Up to eight bits of data

I/O are also provided that can be used for input or output. The

ADS1240 and ADS1241 are designed for high-resolution measure-

ment applications in smart transmitters, industrial process control,

weigh scales, chromatography, and portable instrumentation.
