MAX11259 24-Bit, 6-Channel, 16ksps, 6.2nV/Hz PGA, 2 Delta-Sigma ADC with I C Interface General Description Benefits and Features The MAX11259 is a 6-channel, 24-bit delta-sigma ADC High Resolution for Industrial Applications that that achieves exceptional performance while consuming Require a Wide Dynamic Range very low power. Sample rates up to 16ksps allow preci- 133dB SNR at 50sps sion DC measurements. The MAX11259 communicates 124dB SNR at 1000sps 2 via an I C-compatible serial interface and is available in a Longer Battery Life for Portable Applications small (3mm x 3mm) WLP package. 2.2mA Operating Mode Current The MAX11259 offers a 6.2nV/ Hz noise programmable 1A Sleep Current gain amplifier (PGA) with gain settings from 1x to 128x. Single or Split Analog Supplies Provide Input Voltage The integrated PGA provides isolation of the signal inputs Range Flexibility from the switched capacitor sampling network. The PGA 2.7V to 3.6V (Single Supply) or 1.8V (Split Supply) also enables the MAX11259 to interface directly with high- Enables System Integration impedance sources without compromising available dy- Low Noise, 6.2nV/ Hz PGA with Gains of 1, 2, 4, 8, namic range. 16, 32, 64, 128 The MAX11259 operates from a single 2.7V to 3.6V ana- 6-Channel, Fully Differential Input log supply, or split 1.8V analog supplies, allowing the Enables On-Demand Device and System Gain and analog input to be sampled below ground. The digital sup- Offset Calibration ply range is 1.7V to 2.0V or 2.0V to 3.6V, allowing commu- User-Programmable Offset and Gain Registers nication with 1.8V, 2.5V, 3V, or 3.3V logic.
