DDC114IRTCR

Analog To Digital Converters (ADC) Overview

The DDC114IRTCR is a quad-channel, 20-bit analog-to-digital converter manufactured by Texas Instruments. It features four independent current-input channels with integrated chopper-stabilized amplifiers and delta-sigma modulators. The device operates within an industrial temperature range of -40°C to +85°C and utilizes a 32-pin TSSOP package. Key electrical parameters include a supply voltage range of 2.7V to 5.5V for both analog and digital sections, a typical quiescent current of 6mA per channel, and a serial interface supporting clock frequencies up to 40MHz. The architecture provides high precision for low-level current measurements.
