Two selectable differential input channels Function: Accepts two independent differential sensor inputs for accurate, noise-resistant measurements. Benefit: Allows monitoring of two sensors or redundant inputs without external multiplexers, simplifying system design. On-chip active, low-noise PGA with selectable gains of 32, 64 and 128 Function: Integrated programmable gain amplifier (PGA) amplifies small differential signals before conversion. Benefit: Improves signal-to-noise ratio for low-level sensors (for example, strain gauges and load cells) and eliminates the need for external amplification stages. Performance: Low-noise on-chip amplification delivers cleaner measurements and reduces PCB area and component count. On-chip power-supply regulator for load-cell and ADC analog power Function: Built-in regulator supplies stable analog power to sensors and the ADC analog section. Benefit: Reduces sensitivity to external supply noise, minimizes the number of power components required, and simplifies power routing on the PCB. Compatibility: Designed to provide the analog supply needs for load-cell circuits and attendant ADC sections. On-chip oscillator with no external components required (optional external crystal supported) Function: Integrated clock source that can run without external components, with the option to connect an external crystal for tighter frequency stability. Benefit: Enables a ready-to-run solution that saves BOM cost and board space while offering an upgrade path for precision timing when needed. Key advantages at a glance Simplified system design: Multiple necessary functions (inputs, PGA, regulator, oscillator) are integrated on-chip, reducing external parts and board complexity. Compact implementation: On-chip integration frees PCB area compared with discrete solutions. Reliable analog performance: Low-noise PGA and dedicated analog regulation improve measurement stability and accuracy. Flexible configuration: Two differential channels, selectable gains, and optional external crystal support accommodate a range of sensor and precision requirements. Typical applications Precision weighing systems: Directly interface load cells, use selectable PGA gain to match sensor sensitivity, and rely on the on-chip regulator and oscillator for stable analog performance. Industrial sensor modules and data acquisition: Monitor two differential sensors with low-noise amplification and minimal external components for compact, robust sensor nodes. Portable measurement instruments: Save space and BOM cost with integrated amplifier, regulator, and oscillator while preserving the option for improved clock stability via an external crystal. Compatibility and integration notes Intended for use with differential sensors such as load cells and strain gauges and with ADC analog front ends that require stable analog supplies. On-chip functions reduce the need for external amplifiers, regulators, and clocks; an external crystal can be added when higher timing accuracy is required. This integrated front-end provides a compact, low-noise, and flexible solution for systems that need accurate differential signal measurement, straightforward power management for analog circuits, and an easy-to-deploy clock source.
