Two selectable differential input channels Why it matters: Connect two separate differential sensor inputs or a single bridge sensor with differential readout without extra multiplexers. Saves board space and reduces wiring complexity while preserving measurement integrity. Benefit: Enables multi-sensor setups or redundant measurements for improved reliability. On-chip active low-noise PGA with selectable gains of 64 and 128 Why it matters: High selectable gains amplify small sensor signals at the source, improving signal-to-noise ratio before conversion. Benefit: Better measurement sensitivity and accuracy for low-level signals from load cells and strain gauges, with options to match different sensor sensitivities. On-chip power supply regulator for load-cell and ADC analogue power Why it matters: Provides a dedicated analogue supply without requiring external regulators or complex power routing. Benefit: Simplifies bill of materials, reduces external components, and improves analogue supply stability for more consistent measurement results. On-chip oscillator that requires no external component, with optional external crystal Why it matters: Built-in clocking eliminates the need for an external oscillator in many designs; an optional crystal can be added when tighter timing stability is required. Benefit: Speeds up qualification and assembly for simple designs while offering a path to higher precision timing when needed. Key attributes and compatibility Function: Dual differential inputs, integrated low-noise programmable gain, internal regulator for analogue supplies, integrated oscillator with external crystal option. Compatibility: Designed for use with bridge sensors such as load cells and other differential transducers; intended to drive the analogue supply needs of the ADC subsystem. Size and integration: Single-chip solution reduces PCB area and external BOM compared with discrete amplifier, regulator, and oscillator implementations. Performance: Low-noise analog front-end with high fixed gains (64 or 128) and a stable on-chip power/clock infrastructure for reliable measurements. Practical application examples Digital weighing scales: Directly interface a load cell to the differential input, use the PGA to amplify the signal and the on-chip regulator to power the sensor and analogue circuitry, minimizing external parts for compact consumer or retail scales. Industrial force-sensing modules: Monitor two independent force sensors or run a redundant measurement channel; integrated oscillator keeps system timing simple, and optional external crystal can be added for controller synchronization. Portable or battery-powered measurement nodes: Reduce power and component count by using the on-chip regulator and oscillator, improving battery life and simplifying enclosure design while maintaining low-noise amplification of small sensor signals. Why choose this device Reduces system complexity by integrating amplification, analogue power regulation, and clocking on a single chip. Improves measurement accuracy through a low-noise PGA with selectable high gains. Supports compact, cost-effective designs with the flexibility to add an external crystal when required for higher timing precision. Typical design benefits Lower BOM and assembly cost Smaller PCB footprint Easier certification and testing due to fewer discrete components Clear upgrade path from a simple reference design (no external oscillator) to higher-precision systems (external crystal) without changing the analogue front-end architecture
