Overview
The TLA2021IRUGT, produced by Texas Instruments, is a 12-bit, single-channel delta-sigma analog-to-digital converter (ADC) designed for low-cost system-monitoring applications. This device is part of the TLA202x family, which includes the TLA2021, TLA2022, and TLA2024. The TLA2021 is notable for its ultra-small X2QFN package, measuring 2 mm × 1.5 mm, making it ideal for space-constrained designs. It integrates a voltage reference, oscillator, and an I2C-compatible interface, supporting both standard-mode and fast-mode operations. The device is suitable for various monitoring tasks such as supply or battery voltage supervision, current sensing, and temperature measurements.
