Analog to Digital Converters

ADC108S102CIMT Description

The ADC108S102CIMT is a 10-bit, 1 MSPS, 8-channel successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. Designed for precision signal acquisition, it operates with a single-ended input and supports a 2.7V to 5.25V dual supply range (analog and digital), making it versatile for mixed-voltage systems. The device features a SPI/DSP-compatible serial interface, ensuring seamless integration with microcontrollers and digital signal processors. Packaged in a 16-pin TSSOP, it is optimized for space-constrained applications. Though marked obsolete, it remains relevant in legacy designs due to its robust performance and ease of use.

ADC108S102CIMT Features

• 10-Bit Resolution: Delivers precise digitization for moderate-resolution applications.
• 1 MSPS Sampling Rate: Suitable for dynamic signal processing in real-time systems.
• 8 Single-Ended Inputs: Multiplexed architecture simplifies multi-channel data acquisition.
• Wide Supply Range (2.7V–5.25V): Compatible with 3.3V and 5V logic systems.
• Low Power Consumption: Ideal for battery-powered or energy-sensitive designs.
• SAR Architecture: Ensures deterministic latency and high linearity.
• Internal Reference: Derives reference voltage from supply, reducing external components.
• SPI/DSP Interface: Enables straightforward communication with host processors.

ADC108S102CIMT Applications

• Industrial Control Systems: Monitoring sensors (temperature, pressure) with moderate speed requirements.
• Portable Instruments: Data loggers or handheld devices benefiting from low power and small footprint.
• Automotive Subsystems: Non-critical sensor interfaces (e.g., cabin climate control).
• Consumer Electronics: Audio processing, touch panels, or display calibration.
• Legacy Upgrades: Replacing older ADCs without redesigning analog front ends.

Conclusion of ADC108S102CIMT

The ADC108S102CIMT balances speed, resolution, and power efficiency, making it a pragmatic choice for cost-sensitive, multi-channel ADC applications. Its obsolete status limits new designs but ensures reliability in existing deployments. Engineers value its simplicity, wide voltage compatibility, and integrated reference, though modern alternatives may offer higher resolution or lower power. For legacy systems or applications where 10-bit precision suffices, this ADC remains a viable solution.
