The DA-01 Differential Amplifier is a single channel, differential line receiver and
differentiator. The DA-01 provides a non-inverting amplifier followed by inverting
differentiator. The differential line receiver eliminates common-mode problems
associated with differing ground potentials between preamp and data acquisition
system. A BNC input connector is provided for the coaxial cable from an HB-01
HiBand Preamp. BNC output connectors are provided for the amplifier and differentiator
outputs. A 9-pin D connector us used for power. The amplifier provides two poles at
1 MHz to reduce high frequency noise. The differentiator provides two additional poles
at 1 MHz to further reduce high frequency noise. A single-turn pot adjust provides
common-mode balance. please call for pricing
