OPA862IDT

Overview

The OPA862IDT is a high-speed, low-noise differential amplifier manufactured by Texas Instruments. It features two channels with a gain-bandwidth product of 400 MHz and a slew rate of 140 V/us. The device operates on a supply voltage ranging from 3 V to 12.6 V while consuming 3.1 mA of quiescent current per channel. Key electrical specifications include an input offset voltage of 50 uV, a common-mode rejection ratio of 120 dB, and an output current capability of 60 mA per channel. It utilizes a SOIC-8 surface-mount package and functions within a temperature range of -40 C to +125 C.

Feature Summary

• Converts single-ended signals to differential outputs for ADC driving applications
• Provides high common-mode rejection ratio for improved signal integrity
• Delivers low input voltage noise density for precision signal processing

Applications

• Single-ended to differential conversion for analog-to-digital converters
• High-speed data acquisition systems
• RF and IF signal conditioning circuits

Procurement Notes

Verify the specific suffix IDT corresponds to the SOIC-8 package and tape-and-reel shipping configuration as listed in official Texas Instruments documentation. Confirm RoHS compliance status through the manufacturer's datasheet before procurement. Ensure the ordering part number matches the exact pinout and thermal characteristics required for the target PCB layout design.

Selection Notes

Select this component when designing circuits requiring simultaneous single-ended to differential conversion and high bandwidth. The 400 MHz gain-bandwidth product supports wideband signal processing needs. Consider the 60 mA output drive capability for loading requirements. Verify that the SOIC-8 package fits the available board space and thermal management constraints.

Part Context

This device belongs to the OPA862 family of high-speed differential amplifiers designed for video and communication applications. It integrates matched components to ensure balanced performance across both channels. The series targets applications demanding precise signal translation between single-ended sources and differential inputs without external matching networks.

Replacement Considerations

Consult official Texas Instruments substitution guides for verified alternatives. Cross-reference pinouts and electrical parameters with other members of the OPA86x family or compatible differential amplifier series.
