I'm trying to reproduce an "ultra" low-noise amplifier circuit which calls for several precision amplifiers/modulators (AD549/LF356/AD630). The input source is a Hamamatsu S1223 photodiode capturing a faint optical signal which is oscillating at 1kHz. While the datasheets for these components have many useful suggestions, I do not see a clear recommendation as to what passive components should be used.
After reading this design reference, I'm thinking to settle on all NP0 capacitors and metal film resistors. However, I'd really appreciate if anyone with experience can comment on what the best choices are? (i.e. If some exotic "tantalum" or "mica" capacitor would make a big difference in noise, I'd love to know!)
The circuit is given below. The signal is amplified (AD549), then bandpass filtered (LF356), then frequency-locked (AD630), and finally low-pass filtered (LF356).
Thanks so much!
