OP27
Rev. F | Page 18 of 20
Capacitor C2 and Resistor R2 form a 2 μs time constant in this
circuit, as recommended for optimum transient response by the
transformer manufacturer. With C2 in use, A1 must have unity-
gain stability. For situations where the 2 μs time constant is not
necessary, C2 can be deleted, allowing the faster OP37 to be
employed.
A 150 Ω resistor and R1 and R2 gain resistors connected to a
noiseless amplifier generate 220 nV of noise in a 20 kHz
bandwidth, or 73 dB below a 1 mV reference level. Any practical
amplifier can only approach this noise level; it can never exceed
it. With the OP27 and T1 specified, the additional noise
degradation is close to 3.6 dB (or 69.5 referenced to 1 mV).
