Dear all,
Grateful for advises on books, recommended part numbers (bipolar transistor, JFET, MOS-FET, OP-AMP), application notes or other hands-on design resources for a very low noise pre-amp for ultrasonic sensor.
Input 0.01mV, pizeoelectronic sensor (high impdenece, mega ohm) Output about 3 volts for driving 8 to 10 bits AD converter Freq 1 kHz to 20KHz with reasonably flat response
Many thanks in advance
Simon
