Frequently Asked Questions
What is the bandwidth of the THS4131IDGKG4?
The THS4131IDGKG4 has a nominal -3dB bandwidth of 80 MHz. This bandwidth is sufficient for driving high-speed ADCs in data acquisition, communications, and medical imaging systems where signal components up to tens of megahertz must be accurately amplified with minimal frequency-response rolloff within the band of interest.
What common-mode rejection ratio does the THS4131IDGKG4 provide?
It provides a minimum CMRR of 80 dB and a typical value of 95 dB. High CMRR is critical in differential amplifier applications because it determines how effectively the device rejects noise and interference that appears equally on both input terminals, such as power-supply hum and common-mode EMI in industrial and medical measurement systems.
What amplifier architecture does the THS4131IDGKG4 use?
The device uses a voltage-feedback operational amplifier architecture with integrated frequency compensation. Voltage-feedback topology provides predictable bandwidth and gain behavior, and the internal compensation removes the need for external compensation networks in most applications, simplifying the PCB design process for filters and ADC driver circuits.
What are typical applications for the THS4131IDGKG4?
Primary applications include driving the differential inputs of high-speed ADCs in data acquisition cards, communications receivers, and medical ultrasound front-ends. The device is also used in active bandpass and low-pass filter stages, instrumentation amplifier differential output stages, and any circuit where a low-noise, fully differential signal path is needed up to 80 MHz.
Is the THS4131IDGKG4 RoHS compliant and what package is it in?
Yes, the THS4131IDGKG4 is lead-free and RoHS compliant (Pb-free code: Yes), making it suitable for use in EU-regulated markets. It comes in a small outline surface-mount package (DGK variant), which is compact and compatible with standard SMT automated assembly processes, and is widely available from authorized Texas Instruments distributors globally.
