What are the key features of THS4531IDGK?
- Ultra-low 0.25 mA quiescent current per channel enables battery-operated and always-on sensing applications with minimal power budget
- Fully differential architecture with rail-to-rail output enables direct ADC driving with maximum dynamic range on 3.3 V and 5 V supplies
- 90 dB minimum CMRR (116 dB typical) rejects common-mode noise on differential signal paths for accurate signal conversion
- 2.7 MHz bandwidth supports audio-band and low-frequency data acquisition front ends while maintaining very low power consumption
What is THS4531IDGK used for?
The THS4531IDGK is designed to drive the differential inputs of precision SAR and delta-sigma ADCs in portable medical instruments, industrial sensors, and wearable electronics where power budget is critical. Its 0.25 mA supply current makes it suitable for battery-powered systems requiring continuous analog signal conditioning without excessive drain. The fully differential output also helps reject power-supply noise and reduce even-order distortion in high-resolution data acquisition chains.

Frequently Asked Questions
What is the quiescent current of the THS4531IDGK?
The THS4531IDGK draws only 0.25 mA of quiescent current per channel, which is exceptionally low for a fully differential amplifier. This makes it suitable for battery-operated instruments, IoT sensor nodes, and portable medical devices where minimizing static power consumption is a design priority.
What is the bandwidth of the THS4531IDGK?
The THS4531IDGK has a -3 dB bandwidth of 2.7 MHz, supporting signal frequencies through the audio band and low-MHz range. This bandwidth is sufficient for conditioning signals before digitization with SAR ADCs sampling at rates up to several MSPS in data acquisition applications.
Can the THS4531IDGK drive ADC differential inputs directly?
Yes, the THS4531IDGK is specifically designed as an ADC driver. Its fully differential output with rail-to-rail swing, combined with high CMRR of 116 dB typical, makes it an excellent choice for level-shifting and buffering single-ended signals into the differential inputs of precision SAR and delta-sigma ADCs.
What package does the THS4531IDGK come in?
The THS4531IDGK is housed in an 8-pin MSOP (DGK suffix) package, which provides a very small PCB footprint of approximately 3 mm x 3 mm. This compact package is well suited for space-constrained portable instruments and multi-channel sensor conditioning boards.
What supply voltage range does the THS4531IDGK support?
The THS4531IDGK is designed to operate from a single supply and is compatible with 3.3 V and 5 V rails commonly found in microcontroller-based systems. Its rail-to-rail output enables maximum output voltage swing even at these low supply voltages, which is critical for maintaining ADC dynamic range in low-power designs.
