The THS4531A is an ultra low power, fully differential amplifier designed for applications requiring high performance and low power consumption. It operates with a supply voltage range of 2.5 V to 5.5 V and consumes a typical quiescent current of 250 ¬µA. The amplifier features a bandwidth of 36 MHz at a gain of 1 V/V and a slew rate of 200 V/¬µs, making it suitable for high-speed signal processing. The device offers rail-to-rail output and a negative rail input, which allows for versatile interfacing with various signal sources. It has a low total harmonic distortion (THD) of -120 dBc at 1 kHz and an input voltage noise of 10 nV/,àöHz at 1 kHz, ensuring high fidelity in signal amplification. The THS4531A also provides high DC accuracy with an offset voltage of ¬±100 ¬µV and an offset voltage drift of ¬±3 ¬µV/¬8C over a temperature range of -40¬8C to +125¬8C. Available in multiple package options, including a 10-pin QFN, the THS4531A is ideal for low-power data acquisition systems, differential signal conditioning, and applications where space and power efficiency are critical.
