ADS1213U

ADS1213U Description

The ADS1213U from Texas Instruments is a high-precision, 22-bit sigma-delta analog-to-digital converter (ADC) designed for demanding measurement applications. It integrates a single-channel ADC with SPI interface, supporting differential inputs across 4 input channels. Operating on a 5V analog and digital supply, it delivers a sampling rate of 6.25kSPS, making it suitable for high-resolution data acquisition systems. The device features a programmable gain amplifier (PGA) and supports both external and internal voltage references, enhancing flexibility in signal conditioning. Packaged in a 24-pin SOIC and compliant with ROHS3 and REACH standards, it is ideal for industrial and instrumentation applications requiring long-term reliability.
