MAX11410 24-Bit Multi-Channel Low-Power 1.9ksps Delta-Sigma ADC with PGA General Description Benefits and Features The MAX11410 is a low-power, multi-channel, 24-bit High Resolution And Low Noise For Signal Sources delta-sigma ADC with features and specifications that are With Wide Dynamic Range optimized for precision sensor measurement. 24-Bit Resolution Programmable Gain Amplifier With 1, 2, 4, 8, 16, The input section includes a low-noise programmable 32, 64, and 128 Gain Options gain amplifier (PGA) with very high input impedance and 90dB Simultaneous 60Hz and 50Hz Power Line available gains from 1x to 128x to optimize the overall Rejection dynamic range. Input buffers provide isolation of the 3ppm Typical INL with No Missing Codes signal inputs from the switched-capacitor sampling network when the PGA is not in use, making the ADC Optimized Features For More Efficient System easy to drive even with high-impedance sources. Design 10 Analog Inputs May be Used for Single-Ended/ Several integrated features simplify precision sensor Fully Differential in Any Combination applications. The programmable matched current sources Two Dedicated/One Shared Differential Voltage provide excitation for resistive sensors. An additional Reference Inputs current sink and current source aid in detecting broken On-Demand Offset and Gain Self-Calibration sensor wires. The 10-channel input multiplexer provides the flexibility needed for complex, multi-sensor measurements. Low Power for Efficient Systems GPIOs reduce isolation components and ease control of 2.7V to 3.6V Analog Supply Range switches or other circuitry. 1.7V to 3.6V I/O Supply Range <1A Sleep Mode When used in single-cycle mode, the digital filter settles within a single conversion cycle. The available FIR digital Standard SPI-Compatible Control Interface filter allows single-cycle settling in 16ms while providing Selectable Internal/External Oscillator more than 90dB simultaneous rejection of 50Hz and 60Hz Operating Temperature Range from -40C to +125C line noise. Small 28-Pin 4mm x 4mm TQFN Package: The integrated on-chip oscillator requires no external Lead-Free and RoHS Compliant components. If needed, an external clock source may be used instead. Control registers and conversion data are accessed through the SPI-compatible serial interface. Applications Sensor Measurement Portable Instruments Ordering Information appears at end of data sheet.
