Key Features
- Voltage-feedback op-amp with 35 MHz bandwidth (-3 dB) and ultra-low harmonic distortion for high-fidelity ADC driving and active filter applications
- Integrated shutdown pin reduces supply current to near zero when disabled, enabling power-managed multi-channel analog front-end designs
- 56 dB typical common-mode rejection ratio and 52 dB minimum CMRR with 15 µA bias current at 25°C for precision differential signal conditioning in small outline package
Applications
The THS4211DGN is used in ADC driver circuits and active anti-aliasing filters where ultra-low distortion at signal frequencies up to 35 MHz is essential for maintaining dynamic range in data acquisition systems. Its shutdown feature allows multichannel analog front-ends to power-gate inactive channels, reducing total system power in portable test instruments and medical monitoring devices. The voltage-feedback architecture also suits active Butterworth and Chebyshev filter stages in communications signal processing and software-defined radio IF chains.

Frequently Asked Questions
What is the -3 dB bandwidth of the THS4211DGN and how does it affect ADC anti-aliasing filter design?
The THS4211DGN has a -3 dB bandwidth of 35 MHz, enabling it to drive ADCs sampling at up to 70 MSPS with adequate signal bandwidth. An active low-pass anti-aliasing filter built around the THS4211DGN can be set with a cutoff frequency of 10 MHz to 20 MHz using external RC components, attenuating aliasing artifacts by more than 40 dB before the ADC input and preserving signal integrity for 12-bit to 14-bit converters.
How does the shutdown function of the THS4211DGN reduce power in a multichannel analog system?
The THS4211DGN includes a shutdown pin that, when asserted, reduces the amplifier supply current from its active value to near zero microamperes. In a multichannel signal conditioning board with 8 or more THS4211DGN amplifiers, asserting shutdown on unused channels eliminates their quiescent dissipation, cutting total analog front-end power by 50% or more in duty-cycled measurement systems operating from battery or limited power budgets.
What CMRR specification does the THS4211DGN provide and how does it affect differential signal rejection?
The THS4211DGN provides a typical CMRR of 56 dB and a guaranteed minimum of 52 dB, meaning common-mode signals such as 50 Hz or 60 Hz power-line interference are attenuated by a factor of approximately 400:1 at the output. For a differential sensor signal of 100 mV peak, a 1 V common-mode noise signal is reduced to about 2.5 mV referred to the input, maintaining signal-to-noise ratio in ground-referenced measurement applications.
For a 35 MHz active filter requiring ultra-low distortion, how does THS4211DGN compare to general-purpose op-amps?
General-purpose op-amps such as the LM741 or TL071 have gain-bandwidth products of 1 MHz to 3 MHz and high harmonic distortion at frequencies above 100 kHz, making them unsuitable for 35 MHz filter stages. The THS4211DGN delivers 35 MHz -3 dB bandwidth with ultra-low distortion, a 20 µA maximum bias current, and 56 dB CMRR, enabling precision Sallen-Key or multiple-feedback filter topologies at IF frequencies used in communications and test instrumentation that general-purpose amplifiers cannot achieve.
