ADS7841ES/2K5G4

Analog To Digital Converters (ADC) Overview

The ADS7841ES/2K5G4 is a 12-bit, 4-channel serial output sampling Analog-to-Digital Converter (ADC) manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7V to 5V and supports up to 200kHz conversion rates. The device features an internal multiplexer allowing for four single-ended or two differential input channels. It utilizes a Successive Approximation Register (SAR) architecture with a synchronous serial interface compatible with standard SPI protocols. The ES grade variant is specified over an extended temperature range of –40°C to +125°C. Typical power dissipation is 2mW at a 200kHz throughput rate with a +5V supply, while shutdown mode reduces consumption below 15µW.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix /2K5G4 corresponds to tape and reel packaging containing 2500 devices per reel. Confirm that the 'ES' designation indicates the extended temperature grade (-40°C to +125°C). Ensure RoHS compliance documentation matches the G4 suffix requirements. Cross-reference the manufacturer part number against current production status notices to confirm availability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high accuracy is required in space-constrained, battery-operated environments. The 12-bit resolution and low noise characteristics suit precision measurement tasks. Consider the extended temperature range if the application operates in harsh industrial conditions. Verify that the serial interface timing aligns with the host microcontroller's capabilities for optimal throughput.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS7841 family of 12-bit ADCs from Texas Instruments. It serves as an alternate source for the MAX1247. The family includes variants with different temperature grades and package options, such as DIP-16 and SSOP-16. The ES grade specifically denotes the extended temperature capability compared to the standard E and EB grades.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet identifies the MAX1247 as an alternate source for the ADS7841 series. Verify pin compatibility and electrical specifications before substitution. Other members of the ADS7841 family may offer similar functionality but differ in temperature ranges or packaging.
