THS4130CD

Instrumentation, Op Amps, Buffer Amps Overview

The THS4130CD is a fully differential input/output amplifier from Texas Instruments, housed in an 8-pin SOIC package. It operates within a supply voltage range of 5 V to 30 V and supports temperatures from 0°C to +70°C. Key electrical parameters include a small-signal bandwidth of 166 MHz at ±5 V, a slew rate of 67 V/µs, and a gain-bandwidth product of 215 MHz. The device features low noise with 1.25 nV/√Hz input-referred voltage noise and achieves total harmonic distortion of -100 dBc at 250 kHz.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Provides true fully differential signal processing for enhanced common-mode noise rejection and even-order nonlinearity suppression.
• Includes an active-low power-down pin to reduce quiescent current consumption when the device is not in use.
• Supports single-ended to differential conversion and differential-to-single-ended translation within a high-voltage signal chain.

Instrumentation, Op Amps, Buffer Amps Applications

• Differential ADC driver
• Single-ended to differential conversion
• Differential antialiasing filter
• Medical ultrasound systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the specific part number suffix 'CD' corresponds to the commercial temperature range (0°C to +70°C) rather than the industrial range (-40°C to +85°C). Confirm the package type matches the required PCB footprint, as other variants like ID or DGN exist. Ensure the design accounts for the thermal pad requirements if utilizing alternative packages, though the SOIC variant does not feature one.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fully differential architecture is required for driving ADCs or balancing signals. The THS4130 includes a dedicated power-down pin, unlike the THS4131 which lacks this feature. Consider the 166 MHz bandwidth and 67 V/µs slew rate for high-speed applications. Verify that the 0°C to +70°C operating range meets the environmental specifications of the target system.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the THS413x family of high-speed, low-noise fully differential amplifiers fabricated using a complementary bipolar process. The family offers rail-to-rail outputs and high supply capability up to ±15 V. The THS4130CD specifically denotes the commercial grade version packaged in standard SOIC-8 format, distinguishing it from the industrial grade and alternative package options available within the same series.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The THS4131CD serves as a functional substitute but lacks the power-down pin found on the THS4130CD. Other members of the THS413x family may require verification of temperature ranges and package types before substitution.
