MAX11270 24-Bit Delta-Sigma ADC

Analog Devices MAX11270 24-Bit Delta-Sigma Analog-to-Digital Converter (ADC) 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 Analog Devices MAX11270 offers a 6.5nV/ noise programmable gain amplifier with gain settings between 1x to 128x. Optional buffers are also included to isolate the signal inputs from the switched capacitor sampling network. This allows the device to be used with high-impedance sources without compromising the available dynamic range.
