ADS7805UBG4

Analog To Digital Converters (ADC) Overview

The ADS7805UBG4 is a 16-bit, 100 kS/s sampling Analog-to-Digital Converter (ADC) from Texas Instruments. It utilizes a CMOS Successive Approximation Register (SAR) architecture with an internal sample-and-hold circuit. The device operates on a single +5V supply and features a standard ±10V input range achieved through laser-trimmed scaling resistors. Key electrical specifications include a minimum Signal-to-Noise and Distortion Ratio (SINAD) of 86 dB at a 20 kHz input frequency and a maximum Integral Nonlinearity (INL) error of ±3 LSB. The component is housed in a 28-pin SOIC package and is specified for operation within the industrial temperature range of -25°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with 100 kS/s throughput rate using SAR architecture
• Standard ±10V analog input range with single +5V supply operation
• 86 dB minimum SINAD and ±3 LSB maximum INL performance
• Flexible reference configuration supporting both internal 2.5V and external references

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition
• Precision measurement instrumentation and test equipment
• Data acquisition modules for automated testing environments

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'BG4' corresponds to the specific RoHS-compliant and tape-and-reel packaging variant as defined in the manufacturer's current documentation. Confirm the package designation matches the SOIC-28 physical dimensions provided in the datasheet. Ensure compatibility with the required industrial temperature range specifications before integration into final designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 100 kS/s sampling speed are required for single-ended signals. It is suitable for applications needing a wide ±10V input range without external attenuation circuits. Consider the parallel interface requirements and the need for appropriate digital isolation or latching if bus activity occurs during conversion cycles.

Analog To Digital Converters (ADC) Part Context

The ADS7805UBG4 belongs to the ADS7805 family of 16-bit ADCs. It is pin-compatible with the 12-bit ADS7804, facilitating design upgrades. The 'UB' suffix typically denotes the SOIC-28 package variant, while 'G4' indicates lead-free and RoHS compliance status according to Texas Instruments standards.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7805U serves as the standard tube-packaged equivalent for the same functional specifications. For lower resolution needs, the ADS7804 offers pin-compatible functionality with 12-bit accuracy.
