MAX11270EUG+

The MAX11270EUG+ is a 24bit, delta sigma analog to digital converter (ADC) with integrated PGA in 24 pin TSSOP package. It 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 1ppm (typical) and 4ppm (maximum). The MAX11270 communicates via an SPI compatible serial interface. It offers 6.5nV/?Hz noise programmable gain amplifier with gain settings between 1x to 128x. Optional buffers are also included to provide isolation of signal inputs from switched capacitor sampling network. This allows MAX11270 to be used with high impedance sources without compromising available dynamic range. The MAX11270 operates from single 2.7V to 3.6V analogue supply or split ±1.8V analogue supplies allowing analogue input to be sampled below ground. The digital supply range is 2V to 3.6V allowing communication with 2.5V, 3V or 3.3V logic. It is used in scientific instrumentation and ATE equipments.
