ADS7810U-1

Analog To Digital Converters (ADC) Overview

The ADS7810U is a 12-bit, 800kHz sampling CMOS analog-to-digital converter (ADC) from Texas Instruments. It features a standard ±10V input range and operates on dual ±5V supplies (+VANA, –VANA). The device integrates a sample/hold circuit, an internal 2.5V reference, and parallel data output latches with 3-state drivers. Key electrical specifications include a throughput rate of 800kHz, a minimum Signal-to-(Noise+Distortion) Ratio (SINAD) of 69dB at a 250kHz input frequency, and maximum Integral Nonlinearity (INL) and Differential Nonlinearity (DNL) errors of ±3 LSB. It is housed in a 28-pin SOIC package.

Analog To Digital Converters (ADC) Feature Summary

High-speed 12-bit resolution with 800kHz throughput rate
Standard ±10V bipolar input range with inherent overvoltage protection to ±25V
Integrated internal 2.5V reference or support for external references between 2.3V and 2.7V
Parallel 12-bit binary twos complement data output with 3-state drivers

Analog To Digital Converters (ADC) Applications

Industrial process control systems requiring high-speed data acquisition
Medical instrumentation such as ultrasound imaging and patient monitoring
Test and measurement equipment including oscilloscopes and spectrum analyzers
Automotive engine management and sensor signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation, as suffixes may indicate variations in temperature grade, packaging format, or lead-free status. Confirm that the supply voltage requirements match the system design, as the ADS7810U requires dual ±5V analog and digital supplies. Ensure proper decoupling capacitors are included in the design to maintain performance specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS7810U when a high-speed 12-bit conversion rate is required alongside a wide ±10V input range without external scaling amplifiers. Consider the integrated reference and sample/hold capabilities to simplify the analog front-end design. Evaluate the power dissipation of approximately 275mW at full speed to ensure adequate thermal management within the SOIC-28 package.

Analog To Digital Converters (ADC) Part Context

The ADS7810 belongs to the ADS78xx family of high-speed ADCs from Texas Instruments. This series is characterized by its use of capacitor-based Successive Approximation Register (SAR) architecture combined with CMOS technology. The ADS7810 specifically targets applications needing fast sampling rates and large input swings, distinguishing it from lower-speed or single-supply variants in the broader data converter portfolio.
