Delta-Sigma ADC are aimed at any type of system-monitoring applications

The Texas Instruments TLA2021, TLA2022, and TLA2024 devices (TLA202x) are simple-to-use, low-power, 12-bit delta-sigma ADCs aimed at any type of system-monitoring applications including current sensing, supply or battery voltage supervision, or temperature measurements. Supplied in an ultra-small, leadless, 10-pin X2QFN package, the TLA2021 and TLA2022 are single-channel ADCs while the TLA2024 features a flexible input multiplexer (MUX) with two differential or four single-ended input measurement options. The devices integrate a voltage reference and oscillator. Additionally, the TLA2022 and TLA2024 include a PGA with selectable input ranges from ±256mV to ±6.144V, enabling both large- and small-signal measurements. The devices communicate via an I2C-compatible interface and operate in either continuous or single-shot conversion mode. They automatically power down after one conversion in single-shot conversion mode, significantly reducing power consumption during idle periods. All of these features, along with a wide operating supply voltage range, make the devices suitable for power- and space-constrained, system-monitoring applications.
