Product Specification

Key Functions

1. 24-bit High-Resolution Analog-to-Digital ConversionDelivers 24-bit no-missing-code performance, supporting a maximum data rate of 2 kSPS (kilosamples per second). It ensures high-precision digitization of analog signals, ideal for applications requiring fine-grained measurement of physical quantities.
2. Integrated Programmable Gain Amplifier (PGA)Features a built-in PGA with selectable gain levels from 1 to 128, enabling amplification of weak input signals (e.g., from sensors) while suppressing noise. This eliminates the need for external amplification circuits, reducing system complexity and cost.
3. Versatile Input MultiplexingEquips a flexible input multiplexer that supports 8 single-ended inputs or 4 differential inputs. It allows the device to interface with multiple sensors or signal sources sequentially, suitable for multi-channel data acquisition systems.
4. Low-Drift Voltage ReferenceIncorporates an on-chip low-temperature-drift voltage reference (typical drift of 5 ppm/°C), ensuring stable reference voltage supply across the operating temperature range of -40°C to +125°C, and enhancing long-term measurement accuracy.
5. Ultra-Low Power ConsumptionOperates at ultra-low quiescent current (as low as 600 nA in standby mode), making it well-suited for battery-powered, portable, or remote monitoring devices where power efficiency is critical.
6. Built-in Sensor Excitation CircuitsProvides integrated current excitation sources, which can directly power resistive sensors (e.g., thermistors, strain gauges, pressure sensors) without additional external driving circuits.
