Overview
The ADC084S021CIMMX/NOPB from Texas Instruments is a low-power, 4-channel, 8-bit analog-to-digital converter (ADC) designed for high-performance and efficiency. This successive-approximation ADC operates with a single supply voltage ranging from 2.7 V to 5.25 V, making it suitable for battery-powered devices and energy-efficient designs. The device features a compact 10-pin VSSOP package, ensuring minimal space usage, and operates over an industrial temperature range of –40°C to 85°C. It supports various serial interfaces such as SPI, QSPI, and MICROWIRE, and is known for its low power consumption, with a typical power usage of 1.6 mW at a 3-V supply and 5.8 mW at a 5-V supply. The ADC also includes a power-down mode that reduces power consumption to as low as 0.12 µW at 3 V and 0.35 µW at 5 V.
