The LMH6643 from Texas Instruments is a dual-channel, low-power operational amplifier designed for high-speed applications. It features a 130 MHz bandwidth and a fast slew rate of 130 V/µs, making it suitable for demanding signal processing tasks.
This amplifier operates over a wide supply voltage range of 2.7 V to 12.8 V and offers rail-to-rail output, allowing for maximum dynamic range, especially in low-voltage systems. The input common-mode voltage range extends below the negative supply rail and within 1 V of the positive supply rail.
With a low supply current of 2.7 mA per channel and an output current capability of up to 75 mA, the LMH6643 balances performance with power efficiency. It is available in SOIC and VSSOP packages, suitable for various board space constraints.
Key electrical characteristics include low input voltage noise of 17 nV/√Hz and low distortion performance, with THD at -62 dBc at 5 MHz. These features make the LMH6643 a versatile choice for active filters, ADC buffers, and portable video applications.
