Overview
Description
The ADS1259IPW is a 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) from Texas Instruments, designed for high-precision, low-noise measurements. It features:
- Ultra-low noise (1.8 µV RMS at 2.5 SPS)
- Low power consumption (3.5 mW at 2.5 SPS)
- Flexible data rates (2.5 SPS to 23.7 kSPS)
- SPI-compatible serial interface
- Internal oscillator & programmable gain amplifier (PGA: 1–128 V/V)
Ideal for industrial sensors, weigh scales, and medical instruments, it operates from ±2.5 V to ±5 V dual supplies or +5 V single supply. The TSSOP-16 package ensures compact integration.
Key benefits include high resolution, low drift, and robust performance in noisy environments. Its self-calibration and offset/drift correction enhance accuracy.
For detailed specs, refer to the datasheet (TI Document SBAS499).
