ADS1114IDGST

Analog To Digital Converters (ADC) Overview

The ADS1114IDGST is a precision analog-to-digital converter manufactured by Texas Instruments. It features a 16-bit resolution and supports sampling rates up to 860 samples per second using a delta-sigma architecture. The device integrates an internal programmable gain amplifier, oscillator, reference, and comparator. It operates on a single power supply ranging from 2V to 5.5V for both analog and digital domains. The component utilizes an I2C serial interface and accepts differential or single-ended inputs. It is housed in a 10-VSSOP surface-mount package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a programmable gain amplifier with selectable gain factors to accommodate various input signal ranges.
• Includes an internal oscillator and voltage reference to minimize external component requirements.
• Features a built-in comparator for threshold monitoring applications without microcontroller intervention.
• Supports flexible input configurations through an internal multiplexer for differential or single-ended signals.

Analog To Digital Converters (ADC) Applications

• Battery-powered instrumentation systems requiring high resolution and low power consumption.
• Industrial process control loops utilizing thermocouples or RTD sensors.
• Weight scales and force measurement platforms needing precise load cell interfacing.
• Environmental monitoring stations measuring low-level sensor outputs.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDGST corresponds to the 10-VSSOP package variant when sourcing. Confirm RoHS compliance status matches project regulatory requirements. Check manufacturer documentation for moisture sensitivity level handling precautions during assembly. Ensure ordering quantities align with standard tape-and-reel or cut-tape availability constraints defined by distributors.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a single-channel or dual-channel configuration is sufficient compared to quad-channel alternatives. Consider the I2C interface compatibility with the host controller's available bus lines. Evaluate the need for the integrated comparator if external logic is currently used for alarm functions. Verify that the 860 SPS maximum data rate meets the system's bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS111x family of four-wire, 16-bit delta-sigma ADCs. It shares architectural similarities with the ADS1113, ADS1115, and ADS1118 but differs in channel count and interface options. The IDGST designation specifically identifies the industrial temperature grade version in the VSSOP-10 package, distinguishing it from other packaging or commercial grade variants within the same series.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1114IDGSR serves as a reel-based alternative offering identical electrical specifications. The ADS1115 provides similar functionality with additional channels. Verify pinout compatibility before substituting with other members of the ADS111x family.
