The NADC24D003FA is an integrated 24-bit delta-sigma (ΔΣ) analog-to-digital converter (ADC). Designed to deliver excellent precision and speed, the NADC24D003FA ADC achieves outstanding low-noise performance with up to 22-bit Effective-Number-of-Bits (ENOB). This makes it an ideal choice for demanding applications where high-precision analog signal conversion is essential for optimal performance.

The key components of NADC24D003FA include a low-noise programmable gain amplifier (PGA), an internal voltage reference of 1.2V or 2.4V, a delta-sigma modulator, a digital filter and a 49.152 MHz oscillator. The characteristics of these key components ensure its high precision signal conversion. Furthermore, in order to achieve higher performance and integration, the NADC24D003FA integrates an input multiplexer with 6 single-ended channels, a temperature sensor and an SPI interface. These integrated features effectively facilitate a compact PCB design and reduce component costs. The NADC24D003FA’s operating voltage ranges from 2.7 V to 3.6 V while its operating temperature ranges from -40 °C to 105 °C. Its package is TSSOP20 with dimension of 4.4 mm x 6.5 mm.
