XL7705B – 16-Bit Sigma-Delta Analog-to-Digital Converter (ADC) – Xinluda

The Xinluda XL7705B is a 16-bit dual fully-differential Sigma-Delta analog-to-digital converter with a 3-wire SPI interface and programmable gain (1-128), housed in a SOP-16W package for low-frequency sensor measurement.

The XL7705B from Xinluda is a 16-bit Sigma-Delta (Σ-Δ) analog-to-digital converter designed for low-frequency, high-resolution measurement applications. It directly converts the small signals produced by sensors into digital data, making it well suited to instrumentation and industrial control designs. The device provides two fully differential input channels, a built-in programmable-gain amplifier, and a simple 3-wire serial interface for straightforward microcontroller integration. The SOP-16W surface-mount package (XL7705B) is the counterpart of the DIP-16 version (XD7705B).
