Operational_amplifier_±15_volt_1_ampere_power_supply

Published:2009/7/20 21:50:00 Author:Jessie

Operational amplifier ±15-volt 1-ampere power supply. The ECG968 and ECG969 positive and negative regulators can be connected as shown to obtain a dual power supply. A clamp diode should be used at the output of the ECG968 to prevent latch-up problems. The regulators have thermal-overload and short-circuit protection. The input capacitors should be 0.33 μF if tantalum or Mylar, or 1.0μF if aluminum. Bypassing the output is also recommended. The same type of dual power supply can be constructed with other ratings of the ECG9XX series of regulator. Ratings are as follows: ECG960, +5 volts; ECG961, -5 volts; ECG962, +6 volts; ECG963,-6 volts; ECG966, +12 volts; ECG967,-12 volts; ECG968; +1 5volts, ECG969,-15 volts; and ECG972, +24 volts (courtesy GTE Sylvania Incorporated).   (View)

FAST_SAMPLE_AND_HOLD

Published:2009/7/20 21:42:00 Author:Jessie

Strobe pulse developed from logic input of 531 opamp IC, turns on JFET Q1 to complete feedback loop to IC1, Q1, and Q2. C1 charges to voltage equal to that of input signal plus gate-to-source offset voltage of Q2. At end of strobe time, feedback loop is broken and C, holds voltage until time of next strobe pulse. Decay in output voltage between samplings is 1mV/s.- Signetics Analog Data Manual, Signetics, Sunnyvale, CA, 1977, p 643-644.   (View)
