ADC104S051CIMMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC104S051CIMMX/NOPB is a low-power, four-channel CMOS 10-bit analog-to-digital converter manufactured by Texas Instruments. It features a successive-approximation register architecture with an internal track-and-hold circuit and operates over a sample rate range of 200 ksps to 500 ksps. The device accepts single-ended analog inputs from IN1 through IN4, which range from 0V to the positive supply voltage (VA). Powered by a single supply between +2.7V and +5.25V, it delivers typical performance metrics including a Signal-to-Noise Ratio (SNR) of 62.7 dB, Differential Non-Linearity (DNL) of ±0.13 LSB, and Integral Non-Linearity (INL) of +0.20/-0.10 LSB. Normal power consumption is 2.7 mW at 3V and 8.6 mW at 5V.

Analog To Digital Converters (ADC) Feature Summary

• Four input channels (IN1-IN4) with straight binary output compatible with SPI, QSPI, and MICROWIRE interfaces.
• Fully specified performance across a wide sample rate range of 200 ksps to 500 ksps.
• Low power consumption: 2.7 mW (typ) at 3V supply and 8.6 mW (typ) at 5V supply.
• High accuracy with 10-bit resolution, no missing codes, and typical SNR of 62.7 dB.

Analog To Digital Converters (ADC) Applications

• Portable battery-powered systems requiring low power consumption.
• Remote data acquisition networks.
• Instrumentation and control systems.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component matches the specific ordering suffix CIMMX/NOPB to ensure correct package type and lead-free status. Confirm that the application environment stays within the specified operating temperature range of -40°C to +85°C. Ensure the analog supply voltage remains strictly between 2.7V and 5.25V to maintain electrical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a multi-channel, low-power solution is required for moderate-speed data acquisition. It is suitable for applications needing simultaneous sampling of up to four signals without external multiplexers. Consider the 10-bit resolution and 500 ksps maximum throughput against system noise requirements and available clock frequencies.

Analog To Digital Converters (ADC) Part Context

The ADC104S051 belongs to the ADC104S family of 10-bit converters. It is pin-compatible with other members of the series, such as the ADC104S021 (50-200 ksps) and ADC104S101 (500 ksps to 1 Msps), allowing for design flexibility regarding speed requirements while maintaining the same footprint.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the ADC104S021 for lower speed applications and the ADC104S101 for higher speed requirements. Other resolutions in the same package include the ADC084S051 (8-bit) and ADC124S051 (12-bit).
