EVALUATION KIT AVAILABLE MAX11259 24-Bit, 6-Channel, 16ksps, 6.2nV/√Hz PGA, Delta-Sigma ADC with I2C Interface General Description Benefits and Features The MAX11259 is a 6-channel, 24-bit delta-sigma ADC that achieves exceptional performance while consuming very low power. Sample rates up to 16ksps allow precision DC measurements. The MAX11259 communicates via an I2C-compatible serial interface and is available in a small (3mm x 3mm) WLP package. ●● High Resolution for Industrial Applications that Require a Wide Dynamic Range • 133dB SNR at 50sps • 124dB SNR at 1000sps ●● Longer Battery Life for Portable Applications • 2.2mA Operating Mode Current • 1μA Sleep Current The MAX11259 offers a 6.2nV/√Hz noise programmable gain amplifier (PGA) with gain settings from 1x to 128x. The integrated PGA provides isolation of the signal inputs from the switched capacitor sampling network. The PGA also enables the MAX11259 to interface directly with high-impedance sources without compromising available dynamic range. ●● Single or Split Analog Supplies Provide Input Voltage Range Flexibility • 2.7V to 3.6V (Single Supply) or ±1.8V (Split Supply) ●● Enables System Integration • Low Noise, 6.2nV/√Hz PGA with Gains of 1, 2, 4, 8, 16, 32, 64, 128 • 6-Channel, Fully Differential Input The MAX11259 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 1.7V to 2.0V or 2.0V to 3.6V, allowing communication with 1.8V, 2.5V, 3V, or 3.3V logic. ●● Enables On-Demand Device and System Gain and Offset Calibration • User-Programmable Offset and Gain Registers Applications ●● ●● ●● ●● ●● Robust Performance in a Small Package • -40°C to +125°C Operating Temperature Range • WLP Package, 3mm x 3mm (6 x 6 Ball Array) Wearable Electronics Weigh Scales Pressure Sensors Battery-Powered Instrumentation Typical Application Circuit 2.7V TO 3.6V REF 10nF AIN0P 2.0V TO 3.6V 1µF REFN REFP AVDD 1nF C0G 1µF DVDD RSTB ADR0 AIN0N SCL MAX11259 ADR1 SDA AIN5P RDYB 1nF C0G AIN5N GPO0 GPO1 GPOGND CAPP CAPN 1nF C0G CAPREG AVSS 220nF 0603 X7R RESISTIVE BRIDGE MEASUREMENT CIRCUIT, I2C CONFIGURATION 19-7749; Rev 0; 9/15 DGND µC PDF
