The ADS1222 from Texas Instruments is a high-performance 24-bit delta-sigma analog-to-digital converter (ADC) designed for demanding measurement applications. It offers two differential input channels and a flexible SPI interface, making it suitable for integration into various systems.
Key electrical specifications include a maximum sample rate of 240 SPS with a 4MHz clock and a 20-bit effective resolution. The device supports a wide analog supply voltage range from 2.7V to 5.5V and features a low current consumption of 300 µA. It also includes features like 50/60 Hz rejection and an on-chip temperature sensor.
Packaged in a compact TSSOP-14, the ADS1222 is well-suited for space-constrained and power-sensitive applications. Its design facilitates easy connection to microcontrollers and supports single conversions with a standby mode to further reduce power consumption.
Applications for the ADS1222 include hand-held instrumentation, portable medical equipment, industrial process control, and weigh scales, where high-resolution and low power are critical.
