The bandwidth of the DLPVA series amplifiers remains constant at 100 kHz for each gain setting. Six DLPVA models offer a high degree of flexibility; FET or bipolar, single-ended or true differential input. The input impedance is 1 MΩ or lower for our bipolar models and an exceptionally high 1 TΩ for our FET models allowing measurements of signals from very high impedance sources. The noise is as low as 0.4 nV/√Hz for the DLPVA-100-BUN-S. The gain of the DLPVA low-frequency voltage amplifiers can be switched remotely or locally in 20 dB steps.

Applications include Ultra-low-noise laboratory amplifier, pulsed thermal EMF analysis, detector preamplifier, integrated measurement systems.
