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.
