EVALUATION KIT AVAILABLE  
MAX11270  
24-Bit, 10mW, 130dB SNR, 64ksps Delta-Sigma  
ADC with Integrated PGA  
General Description  
Features and Benefits  
The MAX11270 is a 24-bit delta-sigma ADC that achieves  
excellent 130dB SNR while dissipating an ultra-low 10mW.  
Sample rates up to 64ksps allow both precision DC and  
AC measurements. Integral nonlinearity is guaranteed  
to 4ppm maximum. The THD is -122dB. The MAX11270  
communicates via an SPI-compatible serial interface and  
is available in a small 24-pin TSSOP package.  
High Resolution for Instrumentation Applications that  
Require a Wide Dynamic Range  
130dB SNR at 1.9sps  
112dB SNR at 1000sps  
20.4-Bit Noise-Free Resolution at 1.9sps  
17.4-Bit Noise-Free Resolution at 1000sps  
Longer Battery Life for Portable Applications  
2.4mA Operating Mode Current  
4.4mA PGA Low-Noise Mode Current  
1μA Sleep Current  
High Accuracy for DC Measurements  
1ppm INL (typ), 4ppm (max)  
The MAX11270 offers a 6.5nV/√Hz noise programmable  
gain amplifier with gain settings between 1x to 128x.  
Optional buffers are also included to provide isolation of  
the signal inputs from the switched capacitor sampling  
network. This allows the MAX11270 to be used with  
high-impedance sources without compromising available  
dynamic range.  
Single or Split Analog Supplies Provide Input Voltage  
Range Flexibility  
The MAX11270 operates from a single 2.7V to 3.6V  
analog supply, or split ±1.8V analog supplies, allowing  
the analog input to be sampled below ground. The digital  
supply range is 2.0V to 3.6V, allowing communication with  
2.5V, 3V, or 3.3V logic.
