ADS1018IDGST

Analog To Digital Converters (ADC) Overview

The ADS1018IDGST is a precision, low-power 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features an integrated multiplexer, programmable gain amplifier (PGA), voltage reference, and oscillator within a compact 10-VSSOP package. The device supports data rates up to 3.3k samples per second (SPS) and accepts differential or single-ended inputs across two or four channels. It operates on a supply voltage range of 2V to 5.5V for both analog and digital domains. Communication is handled via a standard SPI interface. The component is rated for industrial temperatures ranging from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-precision temperature sensor for system monitoring or cold-junction compensation.
• Configurable PGA allows input ranges from ±256mV to ±6.144V for flexible signal measurement.
• Supports continuous conversion mode and automatic power-down in single-shot mode to minimize current consumption.

Analog To Digital Converters (ADC) Applications

• Battery-powered sensor measurement systems requiring low power consumption.
• Industrial process control involving thermocouple or RTD temperature monitoring.
• Portable instrumentation with space-constrained PCB layouts.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GST' corresponds to the 10-VSSOP package variant when sourcing. Confirm RoHS compliance status as specified in the latest manufacturer documentation. Ensure the ordering quantity matches the available packaging options such as cut tape or reels. Cross-reference the manufacturer part number with distributor codes to avoid substitution errors during procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution is sufficient for the application's accuracy requirements. Consider the ADS1118 series if higher 16-bit resolution is necessary, noting the trade-off in sampling speed. Evaluate the PGA settings against the expected input signal amplitude to optimize dynamic range. Verify that the SPI interface compatibility aligns with the host microcontroller's communication capabilities.

Analog To Digital Converters (ADC) Part Context

The ADS1018 belongs to the ADS1x1x family of delta-sigma ADCs from Texas Instruments. This series is designed for applications demanding high accuracy in small form factors. The IDGST designation indicates the industrial temperature grade and the specific VSSOP-10 surface-mount package configuration used in modern electronic designs.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1018IDGSR serves as a reel-based alternative to the cut-tape GST variant. For higher resolution needs, the ADS1118IDGST offers 16-bit performance but at a reduced maximum sample rate of 860 SPS. Both devices share pinouts and functional similarities within the ADS1x1x family.
