Femto DLPVA-100-B-S Voltage Amplifier

The DLPVA series from FEMTO is a family of low-frequency, variable-gain voltage amplifiers (DC to 100 kHz)

The “B” designation indicates a bipolar input stage (as opposed to FET)

The “-S” suffix often indicates a standard configuration (e.g. standard connectors, standard version) in FEMTO’s naming scheme

Bandwidth: DC to 100 kHz

Gain: switchable 20 / 40 / 60 / 80 dB (i.e. up to ×10000)

Input voltage noise: ~2.4 nV/√Hz

Input impedance: 1 MΩ (typical for bipolar models)

Offset drift: ~0.7 µV/°C

Output: low impedance (less than 100 Ω)

Output voltage range: ±10 V (into high impedance loads)

Controls: gain, coupling (AC/DC) switchable; local and remote control possible

Power: ±15 V supply (typical for amplifiers of this class) — FEMTO standard amplifier power rails
