24-Bit  
ANALOG-TO-DIGITAL CONVERTER  
DESCRIPTION  
FEATURES  
● 24 BITS NO MISSING CODES  
The ADS1242 and ADS1243 are precision, wide dynamic  
range, delta-sigma, analog-to-digital (A/D) converters with  
24-bit resolution operating from 2.7V to 5.25V supplies.  
These delta-sigma, A/D converters provide 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  
(PGA = 1), 19 BITS (PGA = 128)  
The input channels are multiplexed. Internal buffering can be  
selected to provide a very high input impedance for direct  
connection to transducers or low-level voltage signals. Burn-  
out current sources are provided that allow for the detection  
of an open or shorted sensor. An 8-bit digital-to-analog  
converter (DAC) provides an offset correction with a range of  
50% of the FSR (Full-Scale Range).  
● PGA GAINS FROM 1 TO 128  
● SINGLE-CYCLE SETTLING  
● PROGRAMMABLE DATA OUTPUT RATES  
● EXTERNAL DIFFERENTIAL REFERENCE  
OF 0.1V TO 5V  
● ON-CHIP CALIBRATION  
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 second-order  
delta-sigma modulator and programmable FIR filter that pro-  
vides a simultaneous 50Hz and 60Hz notch. The reference input  
is differential and can be used for ratiometric conversion.  
● 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  
ADS1242 and ADS1243 are designed for high-resolution  
measurement applications in smart transmitters, industrial  
process control, weight scales, chromatography, and portable  
instrumentation.
