Low Power Analog-to-Digital Converters

Low Power Analog-to-Digital Converters

Texas Instruments has released low power 12-bit analog-to-digital converters (ADCs) designed specifically for system monitoring applications. The TLA202x series of delta-sigma ADCs are offered in ultra-small, leadless, 10-pin X2QFN packages. 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 integrates a voltage reference and oscillator.

Additionally, the TLA2022 and TLA2024 each include a programmable gain amplifier (PGA) with selectable input ranges from ±256mV to ±6.144V, enabling both large and small-signal measurements.
