ADS1018IDGSR

Analog To Digital Converters (ADC) Overview

The ADS1018IDGSR is a 12-bit analog-to-digital converter (ADC) from Texas Instruments, housed in a 10-VSSOP package. It features an integrated multiplexer supporting two differential or four single-ended inputs. The device utilizes a delta-sigma architecture with an internal programmable gain amplifier and reference. It operates on a single supply voltage ranging from 2 V to 5.5 V for both analog and digital domains. The sampling rate reaches up to 3.3 kSPS. Communication is handled via a standard SPI interface compatible with 3.3 V and 5 V systems. The component supports an operating temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperature ranges and voltage levels before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 12-bit resolution and moderate speed are sufficient for the application. Consider the integrated PGA if signal amplification is needed without external components. Verify that the SPI interface timing meets the microcontroller requirements. Compare power consumption figures against other ADCs in the family if energy efficiency is critical.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1x18 family of low-power, high-precision ADCs. It shares architectural similarities with the ADS1118 but offers lower resolution. The IDGSR suffix indicates a specific industrial temperature grade and reel packaging format. It is designed to replace older discrete solutions in compact designs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include the ADS1018IDGST for cut-tape packaging. The ADS1118IDGSR serves as a higher-resolution alternative within the same package. Check for pin-compatible upgrades if increased resolution is required without board redesign.
