Frequently Asked Questions

What is the bandwidth of the THS4551IDGKR and what ADC resolution can it drive?

The THS4551IDGKR has a -3dB bandwidth of 150MHz, which supports driving high-speed and high-resolution ADCs up to 18 bits. Its low noise density and 110dB CMRR preserve signal integrity across the full Nyquist bandwidth of modern SAR and delta-sigma converters.

What are the key precision specifications of the THS4551IDGKR?

Key precision specs include a maximum input offset voltage of 175µV, a minimum CMRR of 93dB (110dB typical), and a maximum bias current of 1.5µA at 25°C (2µA max). These figures make it suitable for precision measurement applications where offset and common-mode errors must be tightly controlled.

What package does the THS4551IDGKR come in?

The THS4551IDGKR is housed in an 8-pin VSSOP (Very Small Outline Package), also known as a MicroSOP-8, with a 0.65mm pin pitch. This compact footprint saves board space compared to standard SOIC-8 packages while maintaining excellent thermal and electrical performance.

What is the operating temperature range of the THS4551IDGKR?

The THS4551IDGKR is rated for the industrial temperature range of –40°C to +125°C. The 'I' in the part number suffix denotes industrial grade, making it appropriate for automotive electronics, industrial automation, and outdoor instrumentation.

Is the THS4551IDGKR a good replacement for single-ended op-amp based ADC drivers?

Yes, the THS4551IDGKR is designed to replace single-ended op-amp pairs used for differential ADC driving. It eliminates external resistor-network matching, provides integrated common-mode output voltage control, and achieves better CMRR and noise performance than discrete solutions, simplifying board layout and reducing component count.
