MAX11410A 24-Bit, Multichannel, Low-Power 1.9ksps Delta-Sigma ADC with PGA General Description Benefits and Features The MAX11410A is a low-power, multichannel, 24-bit High Resolution and Low Noise for Signal Sources delta-sigma (-) ADC with features and specifications with Wide Dynamic Range that are optimized for precision sensor measurement. 24-Bit Resolution PGA with 1, 2, 4, 8, 16, 32, 64, and 128 Gain The input section includes a low-noise programmable 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 Design easy to drive even with high-impedance sources. 10 Analog Inputs May Be Used for Single-Ended/ Fully Differential in Any Combination Several integrated features simplify precision sensor Two Dedicated/One Shared Differential Voltage applications. The programmable matched current sources Reference Inputs provide excitation for resistive sensors. An additional On-Demand Offset and Gain Self-Calibration current sink and current source aid in detecting broken sensor wires. The 10-channel input multiplexer provides Low Power for Efficient Systems the flexibility needed for complex, multi-sensor measurements. 2.7V to 3.6V Analog Supply Range GPIOs reduce isolation components and ease control of 1.7V to 3.6V I/O Supply Range switches or other circuitry. <1A Sleep Mode When used in single-cycle mode, the digital filter settles Standard SPI-Compatible Control Interface within a single conversion cycle. The available FIR digital Selectable Internal/External Oscillator filter allows single-cycle settling in 16ms while providing Operating Temperature Range from -40C to +125C more than 90dB simultaneous rejection of 50Hz and 60Hz line noise. Small, 28-Pin, 4mm x 4mm TQFN Package: Lead-Free and RoHS Compliant The integrated on-chip oscillator requires no external 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.
