ADS7805UBE4

Analog To Digital Converters (ADC) Overview

The ADS7805UBE4 is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates from a single +5V supply and features a standard ±10V input range with a throughput rate of 100kHz. The device integrates a sample-and-hold circuit, internal reference, and clock logic within an SO-28 package. Key electrical specifications include a maximum integral nonlinearity error of ±3 LSB, a signal-to-noise plus distortion ratio of 86 dB at a 20kHz input frequency, and a maximum power dissipation of 100mW. It supports full parallel data output in binary two's complement format.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with 100kHz sampling rate
• Standard ±10V input range using laser-trimmed scaling resistors
• Single +5V supply operation with under 100mW power dissipation
• Internal or external reference options with 86dB minimum SINAD

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Data acquisition systems requiring high linearity
• Precision measurement instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'E4' against current manufacturer documentation to confirm RoHS compliance status and exact package marking. Confirm availability as production data status may vary. Ensure the SO-28 package variant matches the design footprint requirements for the target application.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit SAR ADC with a ±10V input range and 100kHz throughput is required. It is pin-compatible with the 12-bit ADS7804, facilitating upgrades. Consider the internal reference drift of 8 ppm/°C if external precision references are not used. Verify that the digital interface timing meets the system's bus access requirements.

Analog To Digital Converters (ADC) Part Context

The ADS7805 belongs to the ADS7805 family of CMOS analog-to-digital converters. The 'UBE4' designation indicates the SOIC-28 package variant with lead-free/RoHS compliant construction. This part is designed for applications demanding high accuracy and speed in a single-supply environment.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7805U is a pin-compatible alternative within the same series. For lower resolution needs, the ADS7804 offers a 12-bit option with identical pinout.
