Frequently Asked Questions
What CMRR does the THS4150IDGKRG4 achieve and why does that matter for ADC driver designs?
The THS4150IDGKRG4 achieves 83 dB nominal CMRR, meaning common-mode signals such as power-supply ripple and ground bounce are attenuated by more than 80 dB relative to the differential signal. For a 16-bit ADC front-end, this level of rejection is essential because even a few millivolts of common-mode noise at the amplifier input could degrade effective number of bits if not suppressed. The fully differential output also drives the ADC's differential inputs directly, avoiding additional level-shifting components.
How does the fully differential architecture of THS4150IDGKRG4 reduce PCB layout complexity compared to single-ended op-amps?
A fully differential amplifier like THS4150IDGKRG4 generates its own complementary output pair, eliminating the need for a balun transformer or secondary single-ended-to-differential converter stage that single-ended op-amps require. This reduces the component count by at least 2 to 4 passive elements per channel, shrinks the PCB footprint, and keeps trace routing symmetric to maintain the 83 dB CMRR across frequency. The 8-Pin MSOP package further compresses board area compared to larger SOIC or DIP housings.
Which supply configurations does THS4150IDGKRG4 support and how does that affect industrial instrumentation use?
The THS4150IDGKRG4 operates on split supplies suitable for standard ±5 V and ±15 V industrial rails, with a maximum bias current of 15 µA, keeping quiescent power consumption low even when operating from high-voltage dual supplies in 24 V bus systems. This flexibility lets designers use the same amplifier design across benchtop instruments running from ±12 V lab supplies and field-installed sensors powered from ±5 V regulated outputs, reducing the number of distinct BOM entries.
When should THS4150IDGKRG4 replace a conventional single-ended op-amp at the front end of a data acquisition board?
THS4150IDGKRG4 should replace a single-ended op-amp whenever the signal source is located more than 10 cm from the ADC or travels through connectors where common-mode noise exceeds 1 mV, because the 83 dB CMRR of the differential path suppresses this noise before conversion. It also provides a direct path to differential-input ADCs sampling at several MHz, avoiding the half-speed bandwidth penalty that arises when using a single-ended amplifier with an external input transformer. The 8500 µV maximum offset voltage is acceptable for AC-coupled and digitally calibrated systems.
