ADS7813PG4

Analog To Digital Converters (ADC) Overview

The ADS7813PG4 is a low-power, serial interface, 16-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture to achieve a sampling rate of up to 40 kSPS. The device operates with a single 5 V supply and features an internal reference voltage source. It accepts single-ended analog input signals within a 0 V to 5 V range. Key performance metrics include a signal-to-noise ratio (SNR) of 85 dB and differential nonlinearity (DNL) of ±3 LSB. The component is housed in a 16-pin DIP package and supports operation across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-resolution 16-bit SAR ADC core for precise data conversion.
• Includes an on-chip precision reference voltage to simplify system design.
• Supports standard SPI-compatible serial communication interfaces.
• Designed for low power consumption suitable for battery-operated applications.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring high resolution
• Industrial process control monitoring
• Medical equipment signal acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'G4' confirms lead-free and RoHS compliance status as per manufacturer documentation. Confirm the package type corresponds to the PDIP-16 variant when sourcing replacement components. Ensure the operating voltage requirements match the target system's 5 V rail specifications before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 16-bit resolution is required with a moderate sampling speed of 40 kSPS. It is appropriate for designs needing an integrated reference to reduce external component count. Consider the DIP package constraint if PCB layout allows through-hole mounting. Compare against other ADS7813 variants if surface-mount packaging or different pin counts are necessary for the application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7813 family of low-power serial ADCs from Texas Instruments. The family offers various resolutions and interface options. The 'P' designation indicates the PDIP package, while 'G4' typically denotes environmental compliance attributes such as being lead-free and RoHS compliant according to industry standards.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same package may include the ADS7813P. Other variants like the ADS7813U offer the same electrical characteristics but in a surface-mount SOIC package. Verify pin compatibility and thermal requirements when substituting.
