What are the key features of THS4131IDGN?
- Fully differential input and output architecture with 95 dB typical CMRR suppresses common-mode noise in high-speed ADC driver and signal-chain applications
- 80 MHz -3 dB bandwidth with voltage-feedback architecture enables wideband differential signal processing up to IF frequencies
- Low input offset current of 0.5 µA maximum and precision frequency compensation support accurate, stable closed-loop gains in sensitive measurement circuits
What is THS4131IDGN used for?
The THS4131IDGN serves as a high-performance ADC driver in data acquisition systems where a differential input signal must be conditioned and level-shifted to match the input common-mode range of 12-bit to 16-bit SAR or delta-sigma converters. It is also used in active anti-aliasing filter stages preceding high-speed ADCs in communications and instrumentation equipment. Medical ultrasound front-end boards and industrial process analyzers employ the THS4131IDGN for its low noise floor and wide 80 MHz bandwidth in differential signal paths.

Frequently Asked Questions
What bandwidth and CMRR does the THS4131IDGN offer for ADC driver applications?
The THS4131IDGN provides an 80 MHz -3 dB bandwidth and a typical common-mode rejection ratio of 95 dB, with a minimum guaranteed CMRR of 80 dB. These specifications make it suitable for driving 12-bit to 16-bit high-speed ADCs at sample rates up to 65 MSPS while rejecting power supply noise and board-level common-mode interference.
How does the fully differential architecture of the THS4131IDGN reduce noise in signal chains?
By processing signals differentially throughout, the THS4131IDGN rejects common-mode noise coupled from power supplies or adjacent PCB traces by up to 95 dB CMRR. The differential output also doubles the signal swing compared to a single-ended topology, improving the signal-to-noise ratio by approximately 6 dB for the same supply voltage and load conditions.
What supply voltage range does the THS4131IDGN support, and which package does it use?
The THS4131IDGN operates on single or dual supplies with a total supply voltage up to ±15 V (30 V total), accommodating both 3.3 V single-supply and ±5 V to ±15 V split-supply systems. It is housed in an 8-pin MSOP (VSSOP) package with a 0.65 mm pitch, occupying a small footprint suitable for high-density analog signal-chain PCB layouts.
When is the THS4131IDGN preferable to a single-ended op-amp in a filter design?
The THS4131IDGN is preferred when the downstream ADC has a differential input requiring balanced signal drive — a single-ended op-amp would need an external single-to-differential converter adding cost and noise. The THS4131IDGN eliminates that extra stage with its native fully differential I/O, maintains 80 MHz bandwidth, and achieves input offset currents below 0.5 µA, preserving filter accuracy without additional circuitry.
