ADC104S021CIMMX

Analog To Digital Converters (ADC) Overview

The ADC104S021CIMMX is a quad-channel, 10-bit analog-to-digital converter (ADC) manufactured by National Semiconductor. It features a successive approximation register (SAR) architecture with a sampling rate range of 50 ksps to 200 ksps per channel. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V and utilizes a serial interface compatible with standard SPI protocols. Packaged in a 16-pin TSSOP, it integrates an onboard track-and-hold amplifier for each channel, enabling simultaneous multi-channel acquisition without external multiplexing.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel 10-bit SAR ADC with independent track-and-hold amplifiers
• Sampling rates adjustable from 50 ksps to 200 ksps per channel
• Single-supply operation from 2.7 V to 5.5 V
• Serial interface compatible with SPI, QSPI, and Microwire standards

Analog To Digital Converters (ADC) Applications

• Battery-powered instrumentation systems
• Industrial process control data acquisition
• Portable medical devices requiring low power consumption
• Multi-channel sensor interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation, as Texas Instruments acquired National Semiconductor's logic and mixed-signal product lines. Confirm that the 'CIMMX' suffix corresponds to the specific tape-and-reel packaging variant intended for surface-mount assembly. Ensure compatibility with existing PCB footprints for the 16-TSSOP package before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four isolated input channels are required within a compact footprint. The 10-bit resolution balances cost and performance for general-purpose applications. Consider the ADC124S021 if higher 12-bit resolution is necessary, or the ADC084S021 if 8-bit resolution suffices for lower cost constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADCxS021 family of low-power, high-speed ADCs. It serves as the 10-bit resolution variant within a series that includes 8-bit (ADC084S021) and 12-bit (ADC124S021) counterparts. The family shares identical pinouts and software interfaces, allowing for design flexibility across different resolution requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements include the ADC124S021CIMMX for increased resolution and the ADC084S021CIMMX for reduced cost. Verify that the system timing accommodates the specific clock-to-data latency of the substitute device.
