Overview
The ADS1204IRHBR, produced by Texas Instruments, is a high-performance, four-channel analog-to-digital converter (ADC) featuring four delta-sigma (ΔΣ) modulators. This device operates from a single 5-V supply and is designed for medium- to high-resolution measurement applications. It offers a dynamic range of 100 dB and can achieve 16-bit analog-to-digital conversion with no missing codes. The ADS1204IRHBR is ideal for direct connection to transducers in industrial environments and is available in a VQFN-32 (5×5 mm) package.
