BUF802 Wide-Bandwidth High-Input Impedance JFET Buffer

Texas Instruments' 2.3 nV/√Hz open-loop buffer is ideal for data acquisition systems (DAQ)

Image of Texas Instruments' BUF802 Wide-Bandwidth High-Input Impedance JFET BufferTexas Instruments' BUF802 is an open-loop, unity gain buffer with a JFET-input stage that offers low-noise, high-impedance buffering for DAQ front-ends. The buffer supports DC to 3.1 GHz of bandwidth while offering excellent distortion and noise performance across the frequency range. The BUF802 can be used in a composite loop with a precision amplifier in applications that require higher precision performance.

The BUF802 uses an innovative architecture to simplify the design of high-precision, wide-bandwidth composite loops. The adjustable quiescent current pin enables designers to trade bandwidth and distortion for a lower quiescent current, making the buffer device suitable across a wide frequency range. The BUF802 has integrated input and output clamps to protect the device and its subsequent signal chain from overdrive voltages.
