ADS7810U/1KG4

Analog To Digital Converters (ADC) Overview

The ADS7810U/1KG4 is a 12-bit, 800kHz sampling CMOS analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a complete successive approximation register architecture with an integrated sample-and-hold, internal reference, and clock circuitry. The device supports a standard ±10V input range and operates from dual ±5V power supplies. Key electrical specifications include a maximum integral nonlinearity (INL) of ±3 LSB, a maximum differential nonlinearity (DNL) of ±3 LSB, and a minimum signal-to-noise plus distortion ratio (SINAD) of 69dB at a 250kHz input frequency. It utilizes a parallel data interface with 3-state output drivers.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 800kHz throughput rate
• Standard ±10V bipolar input range with inherent overvoltage protection to ±25V
• Integrated 2.5V internal reference or provision for external reference
• Parallel data bus with 3-state outputs and binary twos complement format

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Data acquisition systems requiring high-speed conversion
• Precision measurement instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'G4' against current manufacturer documentation to confirm compliance details such as lead-free status or package variations. Ensure that the SOIC-28 package dimensions match the target PCB footprint requirements. Confirm that the industrial temperature range of -40°C to +70°C aligns with the operational environment constraints.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed 12-bit ADC with a wide ±10V input range is required. It is suitable for applications needing a parallel interface and internal reference capabilities. Consider alternative models if lower pin counts, serial interfaces, or higher resolution are necessary. Ensure the system design accommodates the required ±5V analog and digital supply rails.

Analog To Digital Converters (ADC) Part Context

The ADS7810 belongs to the ADS7810 family of high-speed CMOS ADCs. It is functionally similar to the ADS7819 but offers specific performance characteristics tailored for general-purpose high-speed applications. The device is available in a 28-pin plastic Small Outline Integrated Circuit (SOIC) package designed for surface-mount assembly.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7819UB is documented as having identical specifications to the ADS7810U. Verify pin compatibility and electrical parameters before substitution. Other members of the ADS78xx series may offer different resolutions or interface types.
