ADS7813PB

Analog To Digital Converters (ADC) Overview

The ADS7813PB is a low-power, serial 16-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture and operates with a single-ended input configuration. The device supports an SPI-compatible interface and achieves a sampling rate of 40 kS/s. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 85 dB, a full power bandwidth of 600 kHz, and a maximum power dissipation of 35 mW. Differential nonlinearity (DNL) is specified at 3 LSB, while integral nonlinearity (INL) is +/- 3 LSB. The component is housed in a 16-pin PDIP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal reference voltage capability for simplified system design
• Low power consumption suitable for battery-operated applications
• SPI-compatible serial interface for straightforward microcontroller integration

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific manufacturer datasheet for the ADS7813PB to confirm pinout compatibility and electrical characteristics against your schematic requirements. Ensure that the DIP-16 package dimensions match your PCB footprint constraints. Cross-reference the official specifications for operating temperature ranges and supply voltage tolerances to guarantee reliable operation under your intended environmental conditions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution is required alongside low power consumption and a serial interface. Compare it against the ADS7813U if surface mount packaging is preferred instead of through-hole. Consider the ADS7812PB if 12-bit resolution is sufficient, as it offers similar functionality with potentially different linearity specifications. Verify that the 40 kS/s sampling rate meets your application's bandwidth needs.

Analog To Digital Converters (ADC) Part Context

The ADS7813PB belongs to the ADS781x family of low-power, serial sampling ADCs from Texas Instruments. This series includes variants such as the ADS7812 and ADS7813, which differ primarily in resolution. The 'PB' suffix indicates a 16-pin plastic dual in-line package (PDIP). These devices are designed for applications requiring moderate speed and high accuracy with minimal power usage.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7813U is a direct functional equivalent offered in a surface-mount SOIC-16 package. For lower resolution requirements, the ADS7812PB provides a 12-bit alternative within the same package style.
