ADS7841EG4

Analog To Digital Converters (ADC) Overview

The ADS7841EG4 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 multiplexer supporting single-ended or differential inputs. The device operates on a single supply voltage ranging from 2.7V to 5.25V and supports throughput rates up to 200kHz. Key performance metrics include ±2 LSB maximum Integral Nonlinearity (INL), ±0.8 LSB Differential Nonlinearity (DNL), and a Signal-to-Noise and Distortion Ratio (SINAD) of 72dB. It utilizes a synchronous serial interface compatible with standard SPI protocols.

Analog To Digital Converters (ADC) Feature Summary

• Integrated four-channel analog multiplexer allowing flexible single-ended or differential input configurations.
• Low power consumption with dedicated shutdown mode reducing dissipation below 15µW.
• Programmable resolution selectable between 8-bit and 12-bit via digital control interface.
• Wide reference voltage range from 100mV to VCC enabling flexible input span scaling.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the EG4 suffix indicates lead-free compliance and RoHS adherence per Texas Instruments standards. Confirm package designation matches SSOP-16 requirements for your PCB layout. Ensure voltage levels align with system specifications before ordering.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low-cost, low-power 12-bit ADC with multiple channels is required. Consider the ADS7841EB variant if operation up to +125°C is necessary. Verify that the external clock frequency supports the desired throughput rate within the specified timing constraints.

Analog To Digital Converters (ADC) Part Context

The ADS7841 belongs to the broader ADS784x family of SAR ADCs. It serves as a direct alternate source for the Maxim MAX1247. The EG4 suffix specifically denotes the commercial temperature grade (-40°C to +85°C) in an SSOP-16 package, distinguishing it from the extended temperature ES grade.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7841ES offers identical electrical specifications but supports an extended operating temperature range up to +125°C. The ADS7841E is the standard commercial grade equivalent in the same package. Check pin compatibility and thermal requirements when substituting.
