ADS7805UG4

Analog To Digital Converters (ADC) Overview

The ADS7805UG4 is a 16-bit, 100 kS/s successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates from a single +5V supply with power dissipation under 100mW. The device features a standard ±10V input range and provides full parallel data output in binary two's complement format. Key electrical specifications include a minimum Signal-to-(Noise+Distortion) ratio of 86 dB at a 20 kHz input frequency and an integral nonlinearity error of ±3 LSB. The component is housed in a 28-pin SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with 100 kS/s throughput rate
• Standard ±10V input range with internal laser-trimmed scaling resistors
• Single +5V supply operation with <100mW power dissipation
• Full parallel data output with tri-state drivers and BYTE pin for byte-wise reading

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution 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 'G4' against current manufacturer documentation to confirm RoHS compliance status and exact package marking. Confirm availability as distribution statuses may vary. Ensure proper handling precautions are observed due to electrostatic discharge sensitivity.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 100 kS/s sampling rate are required within a single-supply architecture. It serves as a pin-compatible alternative to the 12-bit ADS7804. Consider the ±3 LSB INL specification for applications demanding high linearity without external calibration.

Analog To Digital Converters (ADC) Part Context

The ADS7805 belongs to the ADS7805 family of CMOS SAR ADCs. It is designed for applications requiring high accuracy and low power. The device integrates a sample-and-hold circuit, reference buffer, and clock logic, eliminating the need for external timing components.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7805U is the standard SOIC-28 variant. The ADS7805UB offers improved linearity (±3 LSB INL). Verify if the 'G4' suffix denotes a specific environmental compliance or packaging update compared to legacy versions.
