ADC08831IM – NATIONAL SEMICONDUCTOR

Overview

The Texas Instruments ADC08831IM is an 8-bit successive approximation register (SAR) analog-to-digital converter designed for efficient data acquisition. Its primary function is to translate analog voltage levels into digital representations with a maximum sampling rate of 250 kSPS. A critical design consideration for this device is the trade-off between its flexible input configuration (single-ended, pseudo-differential, or differential) and the potential for increased susceptibility to common-mode noise when operating in differential modes without proper signal conditioning, impacting overall system accuracy.

Key Features

• 8-bit resolution
• 250 kSPS sampling rate
• Single-channel input (configurable)
• SPI and DSP compatible serial interface
• External voltage reference required
• 8-SOIC (0.154″, 3.90mm Width) surface mount package

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

• Industrial process control signal digitization
• Low-power sensor data acquisition systems
• Consumer electronics audio signal conversion
• Embedded system analog monitoring interfaces
