 12-Bit Analog-to-Digital Converters  - TLA2021
 

描述

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 measurements.

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 applications.
