ADS7818PG4

Analog To Digital Converters (ADC) Overview

The ADS7818PG4 is a 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features four single-ended input channels and utilizes successive approximation architecture for signal conversion. The device operates with a sampling rate of 200 kSPS and communicates via a serial interface compatible with standard SPI protocols. It is housed in a 28-pin Plastic Dual In-Line Package (PDIP). The component supports an analog supply voltage range typically centered around 5V, enabling precise data acquisition for multi-channel applications requiring moderate speed and resolution.

Analog To Digital Converters (ADC) Feature Summary

• Four independent single-ended analog input channels
• 12-bit resolution with successive approximation architecture
• Serial communication interface supporting standard SPI modes
• 200 kSPS sampling rate capability

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Data acquisition modules
• Battery-powered instrumentation
• Portable measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the required 28-pin PDIP footprint during integration. Confirm that the serial interface timing aligns with the host microcontroller's SPI configuration. Ensure the analog input voltage limits are respected to prevent damage. Check RoHS compliance status if environmental regulations apply to the final assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four single-ended inputs are required within a single ADC solution. The 12-bit resolution balances precision and speed for general-purpose applications. Consider the PDIP package only through-hole mounting is necessary. Evaluate power consumption requirements against the 5V supply operation constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS781x family of low-power, 12-bit ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7816 and ADS7817 but differs in channel count and pinout. The 'G4' suffix indicates lead-free and RoHS-compliant manufacturing standards consistent with Texas Instruments' environmental policies.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include the ADS7818E4 or ADS7818P. Verify pin compatibility before substitution. Other family members like the ADS7816 offer fewer channels, while the ADS7817 provides differential inputs.
