Signal Conditioning – Dual Voltage Buffer with Current Drive Module

$395.00

The BUF-01 Voltage Buffer is a dual channel buffer capable of driving up to 50 mA of current on each channel at up to ±10 V output. The buffer has a 2nd order low pass filter with 3 dB point of 119 kHz to remove high frequency noise. The unit’s differential inputs are built to withstand high DC over-voltages up to ±50 VDC and greater than ±100 V transients. Gain of the unit is 1 allowing for minimal insertion issues.
