ADS7841EB

Analog To Digital Converters (ADC) Overview

The ADS7841EB is a 12-bit, 4-channel serial output sampling Analog-to-Digital Converter (ADC) manufactured by Texas Instruments. It features a Successive Approximation Register (SAR) architecture with an integrated four-channel multiplexer. The device operates on a single supply voltage ranging from 2.7V to 5.25V and supports both single-ended and differential input configurations. It achieves a throughput rate of up to 200kHz with a synchronous serial interface compatible with standard SPI protocols. Key performance metrics include a maximum Integral Nonlinearity (INL) and Differential Nonlinearity (DNL) of ±1 LSB, ensuring no missing codes. The component is housed in a 16-lead SSOP package and is specified for operation across a temperature range of –40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated four-channel analog multiplexer supporting configurable single-ended or differential input modes.
• Low power consumption with dedicated shutdown mode reducing dissipation below 15µW.
• High accuracy specifications with guaranteed monotonicity and no missing codes.
• Flexible serial interface allowing data transfer at high clock rates.

Analog To Digital Converters (ADC) Applications

• Battery-powered portable measurement equipment
• Industrial process control systems
• Personal digital assistants and handheld devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape/reel quantity. Ensure the voltage reference and supply rails match the 2.7V to 5.25V operational limits. Confirm that the application environment stays within the –40°C to +85°C specified temperature range for this grade. Check for RoHS compliance status if required by your manufacturing standards.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS7841EB when a low-cost, low-power solution with moderate speed is required. It is suitable for applications needing up to four analog inputs with 12-bit resolution. Consider the external reference requirement and available clock source before finalizing the design. Compare against the ADS7841E if higher linearity specifications are not critical, or the ADS7841ES if extended temperature ranges are needed.

Analog To Digital Converters (ADC) Part Context

The ADS7841 belongs to a family of low-power, high-speed ADCs from Texas Instruments. It serves as a direct alternate source for the Maxim MAX1247. The EB variant specifically denotes the improved linearity grade (±1 LSB INL/DNL) compared to the E grade (±2 LSB INL/DNL), while sharing the same pinout and functional interface.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7841E is a lower-grade alternative with ±2 LSB INL/DNL. The ADS7841ES offers the same electrical characteristics but extends the operating temperature range to +125°C. For non-TI equivalents, the Maxim MAX1247 is documented as a compatible alternate source.
