ADC Single Delta-Sigma 64ksps 24-Bit Serial (SPI, QSPI, Microwire) 24-Pin TSSOP Tube, MAX11270EUG+, Maxim Integrated

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. The MAX11270 offers a 6.5nV/ 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. 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.
