THS4131CDGNG4

Instrumentation, Op Amps, Buffer Amps Overview

The THS4131CDGNG4 is a fully differential input/output amplifier from Texas Instruments, characterized for operation over the –40°C to +85°C temperature range. It features a small-signal bandwidth of 170 MHz and a slew rate of 67 V/µs at ±15 V supply. The device provides a gain-bandwidth product of 215 MHz and achieves –102 dBc total harmonic distortion at 2 VPP and 250 kHz. Input voltage noise is 1.25 nV/√Hz with a 1/f corner at 350 Hz. It operates on single supplies from 5 V to 30 V or dual supplies up to ±15 V, drawing 15 mA quiescent current.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the package designation corresponds to the HVSSOP-8 form factor. Ensure the operating temperature range matches the I-suffix specification requirements for your application environment before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fully differential architecture is required for improved dynamic range and even-order nonlinearity suppression. Consider the HVSSOP-8 package if thermal dissipation via the exposed pad is necessary. Verify that the 170 MHz bandwidth and 67 V/µs slew rate meet the system's signal frequency and transient response requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the THS413x family of high-speed, low-noise fully differential amplifiers fabricated using a complementary bipolar process. The THS4131 variant specifically lacks the power-down pin found in the THS4130, simplifying the design for applications where continuous operation is standard. It serves as a monolithic solution for converting single-ended signals into differential signals.
