ADS7810U/1K

Analog To Digital Converters (ADC) Overview

The ADS7810U/1K is a 12-bit, 800kHz sampling CMOS analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with an integrated sample-and-hold circuit and internal reference. The device supports a standard ±10V input range using ±5V supplies and provides parallel data output in binary twos complement format via 3-state drivers. Key electrical specifications include a maximum integral nonlinearity (INL) of ±3 LSB, a differential nonlinearity (DNL) of ±3 LSB, and a throughput rate of 800kHz. It operates within an industrial temperature range of –40°C to +70°C and is housed in a 28-pin SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 800kHz sampling rate and 1.25µs throughput time
• Standard ±10V bipolar input range enabled by laser-trimmed scaling resistors
• Integrated 2.5V internal reference with external bypass capability
• Parallel 12-bit data bus with 3-state outputs and binary twos complement coding

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-speed data acquisition
• Data acquisition modules for test and measurement equipment
• Signal conditioning interfaces for sensors with ±10V output ranges

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'U/1K' against the manufacturer's current Package Option Addendum to confirm the exact tape-and-reel quantity and packaging configuration. Ensure that the supply voltage requirements (+VDIG/+VANA at +5V and –VANA at –5V) match the target system design before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed 12-bit conversion is required with a wide ±10V input range. It is suitable for applications where minimizing external signal conditioning components is critical due to its integrated scaling resistors. Consider the power dissipation of approximately 275mW at full speed and ensure adequate thermal management for the SOIC-28 package.

Analog To Digital Converters (ADC) Part Context

The ADS7810 belongs to the ADS78xx family of CMOS analog-to-digital converters from Texas Instruments. This series is characterized by its use of capacitor-based SAR technology and integrated clocking and reference circuits, designed to simplify microprocessor interfacing through parallel latched outputs.

Analog To Digital Converters (ADC) Replacement Considerations

Public documentation indicates the ADS7819UB shares identical electrical specifications with the ADS7810U. Verify pin compatibility and package dimensions before substitution.
