PRODUCTION DATA. TLA2021, TLA2022, TLA2024 SBAS846 – NOVEMBER 2017 TLA202x Cost-Optimized, Ultra-Small, 12-Bit, System-Monitoring ADCs 1 1 Features 1 • Industry’s Lowest-Cost 12-Bit Delta-Sigma ADCs • Ultra-Small X2QFN Package: 2 mm × 1.5 mm • Highly Integrated: – 4 Single-Ended or 2 Differential Inputs Make the TLA2024 the Industry’s Highest Channel Density ADC (0.75 mm² per Channel) – PGA (TLA2022 and TLA2024 Only) – Voltage Reference – Oscillator • Low Current Consumption: 150 µA • Wide Supply Range: 2 V to 5.5 V • Programmable Data Rate: 128 SPS to 3.3 kSPS • I2C™ Compatible Interface: – Supports Standard-Mode and Fast-Mode – Three Pin-Selectable I2C Addresses • Operating Temperature Range: –40°C to +85°C 2 Applications • Personal Electronics: – TVs, Tablets, Cell Phones – Wearables – Drones, Toys • Home and Kitchen Appliances • Building Automation: – HVACs, Smoke Detectors • Battery Voltage and Current Monitoring • Temperature Sensing • Battery-Powered, Portable Instrumentation 3 Description 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.
