The SLICE-DHV is a low-noise, high-bandwidth amplifier for controlling piezoelectric transducers.  Designed for controlling pzt-driven tuning elements in ECDLs and cavity length control systems, it will interface easily with home-built or 3rd-party laser systems allowing optimum control.
The SLICE-DHV features two gain levels.  The first is a traditional 20x which gives the user access to the full 0-200 V range with a 0 to 10 V input signal. The SLICE-DHV can also operate at a gain of one (in conjunction with a DC bias) allowing lower-noise control of a ±10 V range.  A wide output range (0-200 V), high current capacity (±90 mA), and low noise (<150 µV rms) makes this amplifier ready to take on any number of high-voltage chores.
Designed to control the repetition rate of a mode locked oscillator, the SLICE-DHV features very high control bandwidth.
Proprietary power supply technology allows the elimination of bulky & expensive linear power supplies while maintaining noise performance.
The SLICE-DHV is a two channel amplifier offering the economics of scale.

The small-signal bandwidth can be higher than 200 kHz.  However, the large signal gain is limited by design.  For a full scale swing (0-200 V), the bandwidth is 20 Hz.
