The TLA2021, TLA2022, and TLA2024 devices (TLA202x) are
easy-to-use, low-power, 12-bit
delta-sigma (ΔΣ) analog-to-digital converters (ADCs) targeted for any type of system-monitoring
applications (such as supply or battery voltage supervision, current sensing, or temperature
measurements). Offered 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 TLA202x integrate a voltage reference and oscillator.
Additionally, the TLA2022 and TLA2024 include a programmable gain amplifier (PGA) with
selectable input ranges from ±256 mV to ±6.144 V, enabling both large- and small-signal
The TLA202x communicate via an
I2C-compatible interface and operate in either continuous or single-shot
conversion mode. The devices 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
TLA202x suitable for power- and space-constrained, system-monitoring
