ADC10154CIWM – NATIONAL SEMICONDUCTOR

Overview

The Texas Instruments ADC10154CIWM is a 10-bit successive approximation register (SAR) analog-to-digital converter (ADC) designed for high-speed data acquisition. Its primary function is to convert analog input signals into digital representations with a maximum sampling rate of 227kSPS, critical for applications demanding precise temporal resolution. A key design consideration for this device is the trade-off between its multi-channel input capability (up to 4) and the potential for channel-to-channel crosstalk, which can degrade accuracy in multiplexed configurations if not carefully managed through proper board layout and signal conditioning.

Key Features

• 10-bit resolution
• Up to 227kSPS sampling rate
• 4 multiplexed input channels (selectable)
