ADS7841EB/2K5

Analog To Digital Converters (ADC) Overview

The ADS7841EB/2K5 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 on-board multiplexer supporting single-ended or differential inputs. The device operates on a single supply voltage ranging from 2.7V to 5.25V and supports conversion rates up to 200kHz. It utilizes a synchronous serial interface compatible with standard SPI protocols. The component is specified over an operating temperature range of –40°C to +85°C and is housed in a 16-lead SSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a four-channel analog multiplexer allowing flexible single-ended or differential input configurations.
• Features low power consumption with a dedicated shutdown mode reducing dissipation to under 15µW.
• Provides high accuracy with ±1 LSB maximum Integral Nonlinearity (INL) and Differential Nonlinearity (DNL).
• Supports programmable resolution between 8 bits and 12 bits via the digital control interface.

Analog To Digital Converters (ADC) Applications

• Data acquisition systems requiring multi-channel signal monitoring.
• Portable test and measurement equipment.
• Industrial process control applications.
• Battery-powered personal digital assistants and handheld devices.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix '/2K5' confirms the tape and reel packaging format containing 2500 devices per reel. Ensure the 'EB' grade designation matches the required ±1 LSB linearity specification for your application. Confirm that the SSOP-16 package dimensions align with your PCB footprint requirements before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS7841EB/2K5 when precise linearity within ±1 LSB is critical compared to the standard E grade. Choose this model if tape and reel handling is preferred for automated surface-mount assembly processes. Consider the 2.7V to 5.25V supply range compatibility with your system's power rails and ensure the serial interface timing meets your microcontroller's clock speed capabilities.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS7841 series of 12-bit ADCs from Texas Instruments. The 'EB' suffix denotes a specific performance grade with tighter linearity specifications than the standard 'E' variant. The '/2K5' suffix indicates the specific shipping configuration as a tape and reel, distinguishing it from tube-packaged versions like the ADS7841EB.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet identifies the MAX1247 as an alternate source for the ADS7841 series. Verify pinout compatibility and electrical parameter alignment when substituting components. No other direct cross-model replacements are documented in the provided official materials.
