ADS7805PG4

Analog To Digital Converters (ADC) Overview

The ADS7805PG4 is a 16-bit Analog-to-Digital Converter (ADC) from Texas Instruments, utilizing a CMOS Successive Approximation Register (SAR) architecture. It features a standard ±10V input range and operates on a single +5V supply with power dissipation under 100mW. The device supports a minimum sampling rate of 100kHz and provides full parallel data output in Binary Two’s Complement format. It includes an internal 2.5V reference or allows for external reference input. The component is housed in a DIP-28 package and is specified for operation over the industrial temperature range of –25°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with no missing codes and a throughput rate of 100kHz
• Standard ±10V analog input range with inherent overvoltage protection up to ±25V
• Single +5V supply operation with maximum power dissipation of 100mW
• Full parallel digital output interface with tri-state drivers and BYTE pin for byte-select reading

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution analog signal acquisition
• Data acquisition systems utilizing microprocessor interfaces
• Precision measurement equipment needing low power consumption

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix PG4 against current Texas Instruments documentation to confirm package type and environmental compliance status. Check the official product page for current production lifecycle status, as availability may vary by region. Ensure the selected package variant matches the required PCB footprint specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and ±10V input range are required with a single +5V supply. Consider the DIP-28 package for through-hole mounting requirements. Evaluate the need for hardware versus software calibration based on offset and gain error tolerances. Ensure the system design accommodates the parallel interface timing constraints and ground separation requirements for optimal performance.

Analog To Digital Converters (ADC) Part Context

The ADS7805 is part of the ADS7805 family of 16-bit sampling ADCs. It is pin-compatible with the 12-bit ADS7804, facilitating upgrades in existing designs. The device is available in both DIP-28 and SO-28 packages, offering flexibility for different manufacturing processes while maintaining identical electrical characteristics across variants.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7805U/1K serves as a tape-and-reel alternative to the tube-packaged ADS7805U. For pin-compatible upgrades involving lower resolution, the ADS7804 is a direct substitute. Verify that any replacement maintains the 16-bit resolution and ±10V input range if those specifications are critical to the application.
