Overview
The Texas Instruments ADS7042IDCUT is a 12-bit, 1-MSPS (mega-samples per second) analog-to-digital converter (ADC) known for its ultra-low power consumption and ultra-small size. This device features a successive-approximation register (SAR) architecture with an integrated sample-and-hold circuit. It operates over a wide analog input voltage range of 1.65 V to 3.6 V and supports a digital supply range of 1.65 V to 3.6 V, making it versatile for various applications. The ADS7042IDCUT is packaged in an 8-pin VSSOP (DCU) package and is specified for operation from –40°C to 125°C, making it suitable for space-constrained, battery-powered systems.
