THS4130CDR

Instrumentation, Op Amps, Buffer Amps Overview

The THS4130CDR is a high-speed, low-noise fully differential I/O amplifier from Texas Instruments. It features a small-signal bandwidth of 170 MHz and a slew rate of 67 V/µs at ±5 V supply. The device operates on a single supply range of 5 V to 30 V with a quiescent current of 15 mA. It includes an active-low power-down pin reducing current to 860 µA. Packaged in SOIC-8 (D), it supports operation from -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Provides true fully differential signal path from input to output for improved common-mode noise rejection.
• Features an active-low power-down pin to reduce quiescent current during idle periods.
• Supports conversion of single-ended signals into differential signals within the same monolithic device.

Instrumentation, Op Amps, Buffer Amps Applications

• Single-ended to differential conversion
• Differential ADC driver
• Differential antialiasing

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'CDR' corresponds to the commercial temperature range (-40°C to +85°C) and SOIC-8 tape-and-reel packaging. Confirm that the 'C' grade meets the required operating temperature specifications for the target environment. Ensure the datasheet revision matches the design requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fully differential architecture is required for high-speed signal processing. The THS4130CDR offers a balance of high bandwidth and low noise. Consider the internal power-down feature if system power management is critical. Verify that the SOIC-8 package fits the available PCB footprint constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the THS413x family of fully differential amplifiers fabricated using a high-voltage complementary bipolar process. The THS4130 variant specifically includes a power-down pin, whereas the THS4131 does not. Both share similar electrical characteristics but differ in functional modes regarding power consumption control.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

THS4131IDR: Identical electrical performance but lacks the power-down pin functionality.

Instrumentation, Op Amps, Buffer Amps FAQ

How is the power-down mode activated?

The power-down mode is activated by pulling the PD pin below the threshold voltage, which is approximately 1.4 V greater than VCC–. Leaving the pin unconnected keeps the device active due to an internal pull-up resistor.

What is the default output common-mode voltage if VOCM is floating?

If the VOCM pin is left floating, the output common-mode voltage defaults to the mid-rail voltage, defined as (VCC+ + VCC–) / 2.
