LJTick-InBuff

Very low bias current (1pA) input buffer which can directly measure pH sensors (electrode type sensors) and other weakly driven or high source impedance signals. The analog inputs on our compatible DAQ products (U3, U6, UE9, T7, T4) have typical bias currents on the order of 20 nA, which is quite low, but the LJTick-InBuff reduces that dramatically.

• Only requires 1pA bias current
• ±10V input range
• Has pads to optionally install gain resistors

Look at the LJTick-InBuff datasheet for more information.
