Maxim Integrated MAX11270
The MAX11270 is a 24-bit delta-sigma ADC that achieves excellent 130dB SNR while dissipating an ultra-low 10mW. The MAX11270 communicates via an SPI-compatible serial interface and is available in a small 24-pin TSSOP package. The MAX11270 offers a 6.5nV/√Hz noise programmable gain amplifier with gain settings between 1x to 128x.| Part No. | MAX11270 |

GENERAL DESCRIPTION
Sample rates up to 64ksps allow both precision DC and AC measurements. Integral nonlinearity is guaranteed to 4ppm maximum. The THD is -122dB. 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. 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.APPLICATIONS
